An updated approach to Virtual Desktop Infrastructure: Azure Virtual Desktop on Azure Stack HCI

Posted on By Mark Wilson

With the general availability of Azure Virtual Desktop (AVD) on Azure Stack HCI, organisations have a powerful new platform for providing virtual desktop infrastructure (VDI) services. No longer torn between complex and expensive server farms, or desktops running in the cloud – the best of both worlds is here.

The complexities of managing an end user computing service

Over the many years I’ve consulted with IT departments, one of the many common themes has been around the complexities of managing end user computing services.

It used to be that their investments in standard PC builds had led to a plethora of additional management products. These days, Windows (or, more accurately, Microsoft 365) does that to such a level that the layers of added products are not needed. With a Modern Workplace solution, we can deploy a new PC from a factory image, log on with a username from a recognised domain (for example user@node4.co.uk), build that PC to meet corporate standards and get the end user up and running quickly with access to their data, all in a secure and compliant manner.

But there have always been edge cases. The legacy application that is critical to the business but doesn’t run on a modern version of Windows. Or the application with a licensing model that doesn’t lend itself to being installed on everyone’s PC for occasional use. For these cases, virtual desktop infrastructure has been a common approach to publish an application or a desktop.

For other organisations, the use of VDI is seen as an opportunity to abstract the desktop from the device. Either saving on device costs by buying lightweight terminal devices that connect to a farm of virtual desktops, or by using the secure desktop container as an opportunity to allow access from pretty much anywhere, because the device doesn’t directly access the organisation’s data.

I’m not going to advocate for one approach over another. Of course, I have Opinions but, at Node4, we start from the position of understanding the business problem we’re trying to solve, and then working out which technology will best support that outcome.

A shift in the landscape

Whilst Microsoft has had its own remote desktop offerings over the years, they’ve tended to partner with companies like Citrix rather than develop a full-blown solution. Meanwhile, companies like VMware had their own products – though with the Broadcom acquisition and sale of its VDI products (including Workspace One and Horizon), their future looks uncertain.

This makes customers uneasy. But there is hope.

Microsoft has not stood still and, for a few years it’s been maturing its VDI in the cloud service – Azure Virtual Desktop.

AVD provides a secure, remote desktop experience from anywhere, delivering a virtualised desktop experience that’s fully optimised for Windows 11 and Windows 10 multi-session capabilities. With various licensing options including within key Microsoft 365 subscription plans, AVD is now an established service. So much so that there are even products and services to help with managing AVD environments – for example from Nerdio. But, until recently, the biggest drawback with AVD was that it only ran in the public cloud – and whilst that’s exactly what some organisations need, it’s not suitable for some others.

A true hybrid cloud solution

(At this point, I’m tempted to introduce a metaphor about when cloud computing comes to ground. But fog and mist don’t conjure up the image I’m trying to project here…)

Recently, there has been a significant development with AVD. It’s largely gone unnoticed – but AVD is now generally available on Azure Stack HCI.

Azure Stack extends the robust capabilities of Azure’s cloud services to be run locally – either in an on-premises or an edge computing scenario. Azure Stack hyperconverged infrastructure (HCI) is a hybrid product that connects on-premises systems to Azure for cloud-based services, monitoring, and management. Effectively, Azure Stack HCI provides many of the benefits of public cloud infrastructure whilst meeting the use case and regulatory requirements for specialised workloads that can’t be run in the public cloud. 

Some of the benefits of running Azure Virtual Desktop on Azure Stack HCI

There are many advantages to running software locally. Immediate examples are to address data residency requirements, latency-sensitive workloads, or those with data proximity requirements. Looking specifically at Azure Virtual Desktop on Azure Stack HCI, we can:

  • Improve performance by placing session hosts closer to the end users.
  • Keep application and user data on-premises and so local to the users.
  • Improve access and performance for legacy client-server applications by co-locating the application and its data sources.
  • Provide a full Windows 11 experience regardless of the device used for access.
  • Unified management with other Azure resources.
  • Make use of fully patched operating system images from the Azure Marketplace.

What about my existing VDI?

Node4 will aid you in finding the best path from your existing VDI to AVD. Our consultants are experienced in using Microsoft’s Cloud Adoption Framework for Azure to establish an AVD landing zone and to take a structured approach to assessing and migrating existing workloads, user profiles and data to AVD.

Why Node4 is best positioned to help

I’ve already written about how Node4’s expert Consultants can help deploy Azure Virtual Desktop to meet your organisation’s specific needs but that’s only looking at one small part of the picture.

Because, for those organisations who don’t want to invest in hardware solutions, we have hosted services for Azure Stack HCI. We also provide flexible and secure communications solutions. And we’re an Azure Expert Managed Services Provider (MSP).

I may be a little biased, but I think that’s a pretty strong set of services. Put them all together and we are uniquely positioned to help you make the most of AVD on-premises, co-located in one of our datacentres, on a Node4 hosted platform, or in the public cloud.

So, if you are looking at how to modernise your VDI, we’d love to hear from you. Feel free to get in touch using the contact details below – and let’s have a conversation.

Unveiling the real treasure: moving beyond ERP to unleash (and protect) the power of data

Posted on By Mark Wilson

In our rapidly changing world, sophisticated ERP solutions are becoming more crucial than ever for organisations looking to streamline operations and strive for operational excellence. But whilst the ERP plays an instrumental role in that, it’s vitally important to recognise that it’s not just the ERP system that holds value – the real treasure is the data within these systems.

For years now, IT leaders have been talking about a “data-centric world” and how to “democratise” access to the hidden treasure that an organisation’s data contains. And it’s still the case that the monumental value and potential of business data should not be understated. But since 2023, we’ve seen a shift. No longer is it just about the data – the rise of generative Artificial Intelligence (AI) tools has moved the conversation on to how AI can be used to help us better understand and use the data that we hold.

When I’ve spoken to our clients, I’ve seen their thirst for AI-driven insights. AI, coupled with robust data, holds the potential to shift paradigms, drive smart decisions and boost operational efficiency. However, before we can unlock this vast potential, the data needs to be structured and labelled correctly.

The value of structured data and correct labelling

When correctly structured and labelled, data empowers organisations to accurately understand their operations, pinpoint potential bottlenecks and unleash the value nestled in their ERP solutions.

In refining this data, we allow AI models to consume it effectively, driving insights that empower organisations to predict trends, anticipate customer needs, enhance supply chain processes, reduce overhead and foster innovation. Essentially, we convert the commonly inaccessible gold beneath the ERP systems into a well-drilled, fully accessible mine that yields precious insights — the real treasure.

But there’s another source of data that exists outside the core business systems. The ERP holds a trove of operational data that we can index, query and search, but our unstructured data has potential, too. We can ingest it to a modern data platform where it can be cleansed and interrogated. The raw information, once difficult to analyse and gain insights from, becomes useful, and the rise of AI assistants like Microsoft Copilot means we need to think about how these new tools can and should be used.

Getting ready for Copilot

As one of the largest Microsoft partners in the UK, Node4 hears a lot of buzz about Microsoft’s Copilot AI Assistants (of which there are several).

Just as Delve taught organisations to think about what could be indexed and searched in SharePoint and elsewhere, there are some preparatory steps needed for Copilot too. Copilot can only see what an individual can see, but often that’s more than was intended.

Node4 can work with clients to assess readiness including privacy, policies, monitoring, integration and training. And, of course, we’re constantly monitoring developments so we can advise on new announcements, like Copilot+.

The spectre of ransomware

Another trend that we’re seeing is the rise in ransomware attacks. Cyber-insurance data from September 2023 showed not only a 12% increase in ransomware claims frequency; but that that 36% of claimants paid ransoms (often after negotiating down the amount). 

In 2024, ransomware attacks are expected to evolve with more sophisticated techniques. And, in the same way that more extreme weather events have demonstrated we really can’t ignore climate change, the rise in ransomware means we can’t say “they won’t go after us” anymore. Ransomware is not just an issue for large multinational organisations – it’s increasingly a problem for small and medium enterprises too.

What this means is that all that data that we’re talking about unlocking value from needs to be protected. Our clients are talking to us about resilience and immutability – the ability to protect their data from attack.

Data resilience and immutability: the cornerstones of a data-centric approach

Data resilience and immutability (the ability of data to endure and remain unchanged, respectively) are vital. They ensure businesses can withstand unexpected events and safeguard their strategic intelligence. This is particularly true in the light of today’s escalating threats, such as ransomware attacks, which have jeopardised many businesses’ operations globally.

Every data-generated insight within an ERP environment is a precious source of intelligence. This intelligence can provide an invaluable competitive edge, and so it’s not surprising that it’s become an enticing target for malicious attacks. Ransomware, in particular, can hold this treasure hostage, dramatically disrupting a business’ operations and possibly leading to insurmountable financial or reputational damage.

In this context, it’s crucial to secure data with impregnable defences against such threats. At Node4, we prioritise data protection, resilience and immutability as cornerstones of our service offerings. The prosperous mine of business intelligence in ERP systems demands top-notch security protocols and safeguards.

The critical necessity of securing data

Just as an ERP system is valueless without correctly structured and labelled data, the impact and efficiency of this data can be catastrophically neutralised without adequate backup and security measures. Recovering data after a devastating event like a ransomware attack can be a painful, costly and time-consuming undertaking. However, these hurdles can be significantly mitigated, if not entirely avoided, through effective backup strategies and stringent data security policies.

At Node4, we believe that securing and regularly backing up data is not just an option – it’s a critical necessity. That’s why we’ve invested in state-of-the-art data centres with high performance interconnects and immutable storage options. The fact that we run our own data centres, as well as being one of Microsoft’s strongest UK partners means we’re able to work with clients for private, hybrid or public cloud. Our business continuity and recovery solutions cover all aspects of data resilience, and this comprehensive protection is imperative to maintain the integrity and availability of data essential to ERP processes.

The journey ahead: from ERP to data-driven intelligence

ERP solutions are undoubtedly substantive components of a robust business structure. They serve as the backbone of operational processes and hold potential to streamline business workflows. Yet it’s crucial to shift our focus beyond the ERP system and unlock the real source of value residing within – structured, organised, and secured data.

As we continue to take organisations on a digital transformation journey, the true winners will be those who understand and master the mechanism that turns raw data into decisive insights. These forward-thinking organisations will harness the power of AI effectively, backed by well-structured and secure data, to drive efficiency, innovation and competitive advantage, while diligently protecting their treasure from emerging threats. This is what we call AI transformation.

The journey from ERP to data-driven intelligence is underway. Embarking on it will not only shape the future of organisations across the world, but also dictate their survival in an increasingly interconnected and data-driven world. In the orchestration of this transformation, the ERP may conduct the score, but it’s the data that composes the symphony and, ultimately, steals the show.

Retrospective: June/July 2024

Posted on By Mark Wilson

In 1999, I left the only company I’d worked at since graduation. After 5 and a half years (plus a year or so during my degree), I moved on from ICL and followed a colleague to Capita, to be part of a new Microsoft practice. I still remember the conversation on the night before I started: “so, what’s it like to be unemployed, Mark?”. Leaving a place where I was comfortable and respected to start again elsewhere was a big deal for me so I wasn’t amused. Even more so as I’d taken out a mortgage on a house a year or so earlier.

I can’t remember the timings but it soon became clear that a recent re-organisation had changed the focus. The Microsoft practice was no longer a priority. My colleague left Capita soon afterwards. I remained, in a strange organisation, like a fish out of water. I made the most of it, built up my technical skills, and annoyed a few people by taking an outsourced client through the Technology Adoption Programme for Exchange Server 2000. (I was told that “our standard is Exchange 5.5. – you can’t just put in a new version”. Well, I did.)

I stuck it out for 18 months before I left to travel and work in Australia. That was a shorter trip than originally intended (a different story, which involved returning to the UK to settle down with Mrs Wilson). The point is that I learned not to build my career around other people. If I moved jobs again, it would be for me (or in one case, redundancy).

So why tell this story? Well, I’ve written on previous posts about my journey into my current team – and I feel like I’ve found a place that suits me and where I can make a difference. But June was an unsettling month as we prepared for a change of leadership for the Node4 Office of the CTO. It’ll all work out – but I won’t pretend I found it easy. And it reminded me that, however much respect I have for my outgoing CTO, there’s only one person responsible for where I take my career – and that’s me.

Right, enough of the career history lesson. What did I get up to more recently?

At work

Work highlights included:

  • Renewal of my Microsoft Azure Solution Architect Expert certifications.
  • Attending the second and third modules of my level 5 leadership and management training (inclusive leadership; and driving and implementing strategic change). I missed the first module in April, so will have to go back next year to learn about developing my personal leadership brand.
  • Two days at Commsverse – a Microsoft Teams conference organised by, among others, two of my former colleagues (Mark Vale and Martin Boam), at a really cool venue (Mercedes-Benz World). I have a whole load of blog posts planned from that event, though the backlog is pretty huge now. In the meantime, here’s my Twitter thread:
  • I managed to get a couple of posts published on the Node4 site, even if my own blog has been a bit quiet:
  • I also got my paws on this one, though only as an editor:
  • A trip to the North East, to help a client define their future technology direction, including facilitating a workshop with around 15 of their team to identify the challenges that they face.
  • Preparing for the audit (and hopefully renewal) of Node4’s Azure Expert Microsoft Solution Provider competency in a few weeks’ time.
  • Time spent together as a team, planning the future for the Node4 OCTO.

At home (the tech)

CCTV

I’ve been looking to install some CCTV at home for a while. Whilst many would recommend I go down the Ubiquiti route (UniFi Protect), I decided to save some money, using Reolink cameras with my existing Synology NAS.

So far I’ve installed an RLC-811A, which was also my first foray into PoE-powered devices (with a UniFi PoE adapter). Despite the low price, it’s remarkably good camera, both day and night, with the added bonus that it’s supported by Home Assistant.

Correlation or causation?

Sadly, it wasn’t enough, but was it really just a co-incidence that, as I changed my addressable LEDs from blue to red and white, England scored a goal in the Euros final?

And some writing

One blog post that did make it out of the door:

Ignore the hype, but think about getting AI ready

At home (the rest)

Whilst I’m not getting to many of Matt’s cycle races at the moment, I did head up to Darlington with him for the British National Circuit Race Championships. The race didn’t end as we hoped – he crashed – but his on-bike camera footage has 2.8 million views on Instagram at the time of writing!

He was back on the bike the next night as we went down to London for the Via Criterium at the London Cycle Festival. Oh my. What an awesome event. And a good result for Matt too…

And he’s got some decent results in some of the other crits… here’s Otley:

That bike didn’t last much longer though… this happened a week or so later, but he did at least jump back on and ride it to the finish!

And only a couple of days ago, he got caught up in a crash at Sheffield. I’ll be glad when the crit season is over.

I’ve been just as busy travelling around the country with Ben, as he visits the universities he might like to apply to. I missed the Warwick weekend but with Exeter, Bath, Bristol, Nottingham and Cardiff it’s been full on. And, just as when I did the rounds with Matt a couple of years ago, it’s left me wishing I could do it all again, knowing what I know now!

And, as for that car that I spent lots of money insuring recently. Yeah, not what I had in mind…

Watching

I haven’t written much recently about our TV watching, but in addition to my Tour de France addiction that has to be fed each July, Nikki and I have enjoyed:

  • All the light we cannot see, on Netflix. Set towards the end of World War 2, this mini series shows how the paths of a blind French girl and a German soldier collide, guided my the medium of radio. As a bit of a radio guy, I found it quite magical, along with this (unrelated) tweet: Where was Hilversum, anyway?
  • Douglas is cancelled, on ITV. Episode 3 is difficult to watch, but persist – the twist at the end of Episode 4 is worth it!

Travelling

I wrote most of this post as I was preparing to head off for a couple of weeks’ travelling with my youngest son. In fact, that’s why the June retrospective is mashed up with half of July… I’ll be off travelling for the other half.

It’s also meant a very busy week getting ready. New purchases from outdoor shops: lightweight sleeping bag; new walking trousers; new trainers. And cleaning my down jacket (because it might still be cold at night in the Swiss Alps). Rab Equipment are ace:

Tomorrow morning we should be catching the Eurostar to Amsterdam. Or we will be if today’s Microsoft Azure/Microsoft 365 outage and the separate but still severe Crowdstrike/Windows outage don’t affect my journey! I really must stop catastrophising…

Ignore the hype, but think about getting AI ready

Posted on By Mark Wilson

AI. AI. AI. It’s everywhere. And I’m sorry, this is another Artificial Intelligence post, but it’s more a “hold your horses” sort of post…

You see, yesterday, I was helping a colleague review slides for an upcoming AI presentation. He wanted to make sure he gets past the hype, but was suggesting we’re coming out of that phase now as we’re seeing some negative press about generative AI.

I disagreed. Generative AI in particular feels like it’s right at the peak of inflated expectations…

Why I think generative AI is at peak hype right now

I know Gartner is just one (albeit influential) analyst firm, and Hype Cycles aren’t everything, but their Hype Cycle for Emerging Technologies (Aug 2023) shows GenAI approaching the Peak of Inflated Expectations and 2-5 years from productivity.

I don’t have a Gartner subscription but the diagram is taken from an article by The Next Web (and also available directly from the Gartner website). Quoting the TNW article directly,

“Gartner’s warning echoed across our conversations with European tech insiders. In 2024, they expect a cautious and pragmatic approach to AI adoption.”

The Next Web: After a year of breathless hype, AI will face reality in 2024

Another source (which is freely available) is the Gartner Emerging Technologies and Trends Impact Radar for 2024. This contains several AI techs, but shows Generative AI starting to break through:

So what does that mean? To answer that question, we look at another Gartner resource – their Top 10 Strategic Technology Trends for 2024. There are several AI-related trends mentioned, but the TL;DR is that now is the time for strategic planning.

It’s time to get AI ready

Move fast and break things is an often-used phrase suggesting agility. But sometimes, breaking things is less than ideal. And moving fast is great – as long as you’re moving in the right direction.

It’s a good time to increase your awareness of trending technologies (including the democratisation of generative AI) and think about how they can provide benefit to your organisation. But don’t worry if you’re not implementing AI right now. You’re not the only one, despite what you might think from reading around.

To take one example, yes, Microsoft Copilot is huge. The productivity benefits could be significant. But consider your AI readiness before turning on features that could expose data and information that you didn’t even know was there. Think about:

  • AI Principles: How will your organisation use AI. What are your boundaries? Can you clearly articulate and have you articulated what you will (and will not) do with AI?
  • AI Ready: Data: This is a good opportunity to examine the data you have, what you use it for, and who can access it. Making sure your data is AI ready means that it is ethically governed, secure, free of bias and accurate.
  • AI Ready: Security: Understand and prepare for new attack vectors that AI makes possible. Create an acceptable use policy for public-facing generative AI products.

Then, when you’re AI Ready, you’ll be in a position to move fast, hopefully without breaking anything.

Monthly Retrospective: May 2024

Posted on By Mark Wilson

May’s update was late, and June’s is in danger of rolling into July, so here’s a few highlights from my life in and around tech…

At work

On the work front, it was a short month – I was on holiday for the last week and with public holidays too there was lots to cram into a few short weeks. Nevertheless, I still managed to:

  • Continue to develop Node4’s new ransomware scanning service.
  • Finalise a dozen product data sheets for our public cloud services.
  • Submit some blog posts to our marketing team to support upcoming campaigns.
  • Keep pushing some pre-sales activities forwards.
  • And mine and Bjoern Hirtenjohann (/in/BjoernHirtenjohann)’s internal Node4 podcast on public cloud was released:

But the biggest activity in the month was presenting at Node4’s Infrastructure Symposium. One of our Practice Directors brought all his teams together to learn about the products and services that we jointly deliver. With four (or five, depending on how you look at it) companies all merged, there’s been a lot of change at Node4 over the last year or so. Getting everyone together is a great way to break down boundaries and understand the direction we’re headed in. And for me it was a chance to outline that our cloud offers span public, private and hybrid delivery models – and that we will deliver what’s right for the client, not for us. We call this Pragmatic Cloud (and I freely admit we didn’t come up with the term, but it I like it a lot).

I also celebrated my 9 year anniversary of joining risual/Node4 in May. And, for those who were confused by my comments last month, I was saying that my recent move has been overwhelmingly positive and I’m in a better place than I have been for a long while!

Elsewhere

Away from work…

  • My youngest son, Ben, passed his driving test. I was ready for a big insurance bill, but what I wasn’t ready for was: a) no decrease on the bill for the 19 year-old’s insurance (now with 2 years’ experience); and b) a 350% increase in premiums between him passing his test 2 years ago and the 17 year-old passing now. Even with a black box, parents as named drivers, etc. the car insurance bill for the two old cars that our family share with the teenagers was around £4500. For contrast, the bill for my Volvo (with just me and Mrs W as drivers) actually fell and is now back under £500. Public transport is just not reliable enough where we live, so the choices are: a) drive the teenagers everywhere; or b) pay the money. I’m still getting over this assault on our savings… some families just won’t have that money and I dread to think how many uninsured cars there are on the road as a consequence.
  • My eldest son, Matt, continues to race his bike up and down the country. After a catastrophic failure of the fork steerer tube, his Canyon road bike was hastily replaced. That meant a drive to Wakefield to collect the new bike, but it is rather lovely. I don’t get to all his races these days but I did manage to watch him in Ixworth and I was in the team car again for the Lincoln GP. Unfortunately, when he went to Ireland to race the Rás Tailteann I had to make do with watching for updates on Twitter!
  • Ben and I have been planning our Interrail trip – and now we have bought our passes along with inbound/outbound travel. Plus, we’re going to be taking the NightJet sleeper train from Berlin to Vienna! There were a few challenges with seat availability (things have changed since last time I went – we can use high speed rail, but there’s limited availability and we need to pay a supplement). This is more of a problem when dates are fixed so we had to change our route a little. On the flip side, with the start and end locked in, the middle section of the holiday is now free for us to be flexible.
  • I completed the home network upgrade. Was the switch from AmpliFi to UniFi worth it? Time will tell. It’s certainly more flexible but it’s cost me more and my house does not lend itself to structured cable runs. Maybe I should have just replaced the broken AmpliFi mesh point but it felt like I could fall into the trap of the sunk cost fallacy.
  • On the home automation front:
    • Octopus Energy sent us a Home Mini, which should give more granular data on electricity consumption, once I get the Home Assistant configuration right (I’m still tweaking).
    • I’ve also continued to play around with Home Assistant, including a bed occupancy sensor (which I can link to turning off the lights). I will admit that’s probably a step too far into nerd territory.
  • The month ended with a short break in Spain. Originally scheduled for May 2021, we never did get to go on a family holiday to Barcelona and the Costa Brava, though Matt made it out there on a training trip to Girona earlier this year. So, half the holiday, with only one of the “children” (though he is now twice the size!), Nikki, Ben and I spent a glorious few days in an around Begur.

Writing

These retrospectives are a bit of a blogging catch-all, but I did write a post on LinkedIn that turned into a blog in its own right. You can read it at the link below:

Monthly Retrospective: April 2024

Posted on By Mark Wilson

Another look back at some of the things I’ve been up to over the last few weeks…

At work

April marks a year since I started my transition to a new role at Node4. I didn’t move over full-time until July, but that’s when I stopped running what was formerly risual’s Architecture team and joined the Office of the CTO. This is not the forum to share the full details but suffice to say I had manouevred myself into a position where I was very unhappy – neither close to the tech nor able to best use my skills to provide value to the organisation and to our clients.

The change in role has been a breath of fresh air: the focus has changed a few times and there have been some bumps on the road; but one thing is core – I get up each morning and think about how best to add value. Whether that’s building out collateral for our public cloud portfolio, developing a new offering to guard against ransomware, helping clients with their IT Strategy or getting some structure around our “thought leadership” outputs.

The month ended with Node4’s “Go To Market” conference, in Nottingham. It’s an opportunity to set the agenda for the coming year and make sure we’re all headed in the same direction. This was the first time I’d attended and it was also a brilliant opportunity to meet some of my colleagues from across the business.

I managed to get myself into the video somehow, despite not officially being one of the presenters…

After two days of socialising, I was completely wiped out and needed some time to decompress. It’s left me thinking a lot about introversion. On the flip side, I also need to work on my FOMO… being one of the last to go to bed on the first night was not smart. At my age, I should know better.

Blogging

As usual, I didn’t find much time to blog this month, but I did write a thing about Enterprise Architecture, based on Dave Clark and Sophie Marshall’s good work…

The Enterprise Architecture Stack

Away from work

It’s not often that I go to the theatre but I saw the 1990s TV sitcom Drop the Dead Donkey was returning in theatre format with the original cast. I then failed to book tickets, missing it in Milton Keynes by a week. I asked myself if I could be bothered to go to Birmingham instead? Well, why not… I had a birthday so that was an opportunity to do something different!

I loved it, but it’s definitely written for an audience of a certain age (and I fit that demographic). For those less familiar with the original TV programme, it’s still amusing, but it does help to understand the characters and how they have developed over 30 years.

A matinee theatre show in a major city gave us an opportunity for a day out. So, afterwards we wandered down to The Custard Factory in Digbeth, for food and drink at Sobremesa and Rico Libre.

Oh yes, and I couldn’t help but be amused when I spotted that the image on the vinyl wrap in the train toilets contained an empty vodka bottle…

Playing with tech

If last month was about Meshtastic, this month has been Home Assistant. After initially installing on a Raspberry Pi to try it out, I quickly moved to a dedicated device and bought a Home Assistant Green. There was nothing wrong with the Pi installation, but I could use a Raspberry Pi 5 for other things. I’m still getting to grips with dashboards but Home Assistant has pulled all of my various smart devices together into one platform. This thread tells some of the story:

Annoyingly though, iCloud’s “was this you?” messages are not very helpful when you have automated services using your account:

I’ve also been upgrading the home Wi-Fi, moving from a consumer AmpliFi mesh to a solution based on UniFi equipment. That’s been an adventure in itself and will probably be a blog post in its own right.

And, I “went viral” (well, certainly had far more engagement than my normal tweets do), with a family service announcement for Wi-Fi updates…

    Travel

    As is usual, supporting Matt with his cycling races has meant a fair amount of travel and this month’s Premier Inn destinations have been… Tiverton and Stockton-on-Tees. Stockton was the overnight stay for the East Cleveland Classic, where I was in the team car all afternoon – and what an experience that was!

    There was also a race in Leicestershire where Matt was in the break for 2 hours before getting caught and then boxed in on the final sprint.

    But the big one was supposed to have been the CiCLE Classic in Rutland, until it was unfortunately cancelled on the day due to biblical rain. I do feel for the organisers in these scenarios, but even more so for the teams that had travelled from overseas.

    Away from cycling, but very exciting, is starting to plan an Interrail trip with Ben this summer. I only have two weeks’ leave available, but i’m pretty sure we’re going to have a brilliant time. It’s not the first time for me – I went solo in the early 1990s – but things have changed a lot since then.

    Wrap-up

    That’s all for this month… May’s nearly over now but I have some notes ready for a review – hopefully not too long after the end of the month!

    Some thoughts on the hype around artificial intelligence

    Posted on By Mark Wilson

    A couple of weeks ago, I wrote something on LinkedIn. It was only supposed to be a short piece. It ended up long enough for a blog post, so I’m re-publishing it here…

    In a week that seems to have had more than its fair share of truly bad AI ideas (including GPT employment vetting and making a single image “sing and talk” from audio), I’m as AI-jaded as anyone right now. So please bear with me on my yet-another-AI-post-on-social media.

    You see, earlier today, someone shared Molly White‘s article about how AI isn’t useless – but is it worth it? It’s a long read (so I recommend listening instead – a great feature of Molly’s website) and there are many parts of the article that resonate for me.

    First up, she compares the current AI hype with Blockchain before in that “they do a poor job of much of what people try to do with them, they can’t do the things their creators claim they one day might, and many of the things they are well suited to do may not be altogether that beneficial”.

    But Molly goes on to talk about some of the use cases where AI is helpful, which I’ll pick another quote from: “I like it for getting annoying, repetitive tasks out of my way; I don’t worry it’s going to take my job.”

    Some of the other quotes that resonated with me were that: “[AI tools] are handy in the same way that it might occasionally be useful to delegate some tasks to an inexperienced and sometimes sloppy intern” and that “ChatGPT does not write, it generates text, and anyone who’s spotted obviously LLM-generated content in the wild immediately knows the difference”.

    I found it interesting when Molly writes about AI-generated images too: “AI-generated images tend to suffer from a similar bland ‘tone’ as its writing, and their proliferation only makes me desire real human artwork more”.

    She also writes about where LLMs are “good enough” – although sadly that seems to be industrialising some of the less desirable behaviours of the Internet (e.g. keyword stuffing and content farms).

    Most importantly, Molly writes about the environmental and human costs of AI – and touches on the truth of it all. Many AI technologies are solutions looking for problems – and really about boosting profits for investors in tech companies.

    And then the final paragraphs nail it for me – I recommend you read Molly’s post instead of me quoting them in full here (or ask an LLM to summarise it ?) but here’s the last sentence, which absolutely matches how I feel about so much technology right now. “We need to push back against endless tech manias and overhyped narratives, and oppose the ‘innovation at any cost’ mindset that has infected the tech sector.”

    I’m not a Luddite. But I do pride myself on my ability to look past the hype and be strategic when it comes to tech. AI’s a long way from its plateau of productivity – and just because we can do something doesn’t mean we should.

    Oops. I appear to have written enough here for a blog post… oh well, at least it was genuine opinion and not generated by an LLM. And thanks for the inspiration, Molly White.

    The Enterprise Architecture Stack

    Posted on By Mark Wilson

    Over the years, I’ve written several posts about IT architecture. Whilst it seems that there is an increasing trend to call experienced IT folks “architects”, one of my core beliefs is that Enterprise Architecture is not the same as “architecting” IT at enterprise scale. Yes, creating an IT architecture that will scale to support a global organisation with thousands of users is “enterprise scale” – but it’s not Enterprise Architecture.

    So what is Enterprise Architecture?

    Like so many things in life, an illustration can really help describe a point. And, a few years ago, I came across an excellent Enterprise Architecture diagram from Dave Clark and Sophie Marshall. You can see it as the featured image at the top of this post and one of the reasons I like it so much is that it’s clear that the technology is only one of several factors in a whole stack of considerations.

    I adapted it (under Creative Commons) but the basic premise of the diagram remained the same – step back from the problem and understand the organisation to consider its needs and requirements. We need to know what is needed before we can can consider solutions! Then, we should ask what good looks like. Don’t just dive in with technology.

    Let’s take each layer in turn… and you’ll see that, right away, I added another layer at the top.

    Purpose

    The purpose is about why an organisation exists. It should be straightforward to answer but is hopefully more than “to deliver value to our shareholders”. A Council may exist to provide services (statutory and otherwise) to citizens. A retailer may exist to (make money and) provide the best selection of fashionable clothing at affordable prices. It’s entirely logical that the organisation’s culture will be strongly linked to its business motivations.

    Many organisations will give an indication of their purpose on their website, or in their company report. For example, the IKEA vision, values and business idea sets out the organisation’s purpose in the form of:

    • A vision: “To create a better everyday life for the many people”; and
    • A business idea: “to offer a wide range of well-designed, functional home furnishing products at prices so low that as many people as possible will be able to afford them.”

    Strategy

    Strategy supports purpose by providing business ambition and goals – a direction in which to head. Storytelling and visualisation are techniques that can be used to communicate the strategy so that it’s well understood by everyone in the organisation. They can also help others who need to work with them (for example business partners). A useful tool for defining business strategy is the Business Model Canvas, based on the book by Alexander Osterwalder and Yves Pigneur.

    Looking briefly at visualisation, Scott Berinato (@ScottBerinato)’s 2016 article for Harvard Business Review on Visualizations [sic] That Really Work stresses the need to understand the message you want to convey before you get down into the weeds. This blog post is a case in point – I want to show that Enterprise Architecture is much more than just technology. And I found a good visualisation to illustrate my point.

    As for storytelling, I’ve seen some fascinating presentations over the years on how to tell a good story to bring a presentation to life. One of the most memorable was at a Microsoft MVP Event in 2017. Tony Wells used this example of how we tell stories to children – and how we (too) often communicate at work:

    (I’m still practicing my storytelling technique, but Hubspot also has what it calls The Ultimate Guide to Storytelling.)

    What, Who and How

    What we do is a description of the products and services that the organisation offers – the business’ capabilities. These may be the value propositions in the Business Model Canvas but I would suggest they are a little more detailed. Strength/Weakness/Opportunity/Threat (SWOT) analysis can be a useful tool here too for identifying what could be done, though the emphasis is probably more on what is currently done, for now.

    Who we do it for is about the consumers of the organisation’s products and services – understanding who the “users” are. Tools might include stakeholder maps and matrices, empathy maps, personas.

    How it’s done is about understanding the methods and processes that deliver “the what” to “the who”. Journey maps, process flow diagrams, storyboards and SWOT analysis can all help.

    Who does it is about the people, where they are located, and how the organisation is structured. In a world of remote and hybrid working it’s even more relevant to understand the (human) network and how it works.

    Software, data and technology

    Only after we’ve understood “the Business layers” (purpose, strategy and the what, who and how) can we move onto the IT. And that IT is more than just infrastructure:

    • The data models that support this. (There may a discussion to be had there about data, information, knowledge and wisdom but that’s a topic in itself.)
    • The software applications that are used to access that data.
    • And the underlying technology infrastructure.

    Why is this important?

    For many years, I was part of and then managed a team of people who were labelled “Enterprise Architects”. During that time, I argued that the term was aspirational and that most of the work we did was Solution Architecture. Maybe that was splitting hairs but we rarely got the chance to drive strategy, or to get involved in designing the organisational structure. Whilst we were experienced at IT, we still operated at the lower levels in the stack: business requirements driving software, data and technology decisions. We wanted to become trusted advisors, but for the most part, the work we performed for our clients was transactional.

    My colleague Ben Curtis (/in/BenCurti5) has an excellent analogy built around perception and perspective. I hope he won’t mind me borrowing it:

    • Perception is about what meets the eye. Imagine you’re walking through a forest and come across a single tree. Your first impression of that tree – its size, shape, colour, and surroundings – is your perception.
    • Perspective is seeing the Forest and the Trees. Now, let’s say you climb to the top of a hill and look down at the entire forest. Suddenly, you see how all the trees are connected, how the sunlight filters through the leaves, and how animals move through the undergrowth. This bigger view – the perspective – gives you a deeper understanding of the forest as a whole.

    Whilst this can be used to show the difference between an individual system and the complete view of an IT environment, I’d suggest that its also about how the IT environment is part of something much larger – an organisation of people and processes, supported by technology, that exists with a purpose and a strategy to make it happen. And that, is the Enterprise Architecture.

    Here are some posts I’ve written previously on IT architecture. I think this is the first time I’ve properly outlined what Enterprise Architecture means though:

    Monthly Retrospective: March 2024

    Posted on By Mark Wilson

    I managed the weeknotes for 9 weeks. The last one was posted as I was sitting on a plane, about to take off for a long weekend away with my wife. And then I started to take stock. I don’t have time for them. What had been a weekly reflective activity had become a chore.

    And then the unwritten thoughts started to build in my mind. There were still things that I wanted to share. And the feedback had been positive, though the weekly cadence was probably too much.

    So here we are. A new concept: Monthly Retrospective; 12 posts a year instead of 52. Maybe a better chance of me getting it out of the door on time too? I don’t promise it will be published exactly on the end of each month (I’m a week into April as I finish this post), but it will be there or thereabouts…

    So what’s up this month?

    Here’s a quick summary of what’s in the rest of the post

    • We have the tech – both at work and at home. Plus a few of the many interesting things I’ve spotted on my Internet travels (I still post most of them on X, and a more professionally curated set of posts on LinkedIn).
    • We have the events – typically evenings, attended to expand my knowledge.
    • We have the entertainment – music, film, TV.
    • We have life – family and friends.
    • And we have the photos – snapshots of life viewed through my iPhone.

    So let’s get started…

    In tech: at work

    I’m busy, busy as always at work, with more organisational changes to keep me on my toes. One thing I’ve tended to avoid in recent years is working on bids. This is partly because I find there’s invariably a slow start and a mad rush to complete before the deadline, and partly because I prefer to work on a consulting-led sell where I have helped to shape the solution. In a competitive tender scenario someone else has influenced the client, so you’re already on the back foot, second-guessing what the client needs cf. what the invitation to tender says they want. In this case, one of my colleagues asked me to help out, and we have a few weeks to create our solution. It’s also a really interesting project so I’m enjoying pulling this solution together.

    Meanwhile, the ransomware service is also moving forwards, though not as fast as I would like (or, more to the point, as fast as my boss would like). All being well, I’ll have something to shout about in next month’s retrospective.

    In tech: at home

    I’m still playing around with Meshtastic, with one node travelling mobile with me and another soon to be set up at home. Here’s the thread with the progress:

    In addition to the excellent Meshtastic website, Andy Kirby’s YouTube channel has tons of information.

    Other home projects include researching which CCTV cameras to put up (almost certainly from Reolink) and how to get an Ethernet cable to them…

    In tech: some of the things I stumbled across this month

    Some bits and pieces:

    • Advice to help build genAI prompts:
    • One of the many issues with QR codes:
    • Remembering some security advice I used last year:
    • One of my favourite design projects:

    In events

    March saw me getting out to a few tech events in the evenings

    • Milton Keynes Geek Night (MKGN) is always a good night out. In truth, it’s not really geeky these days – more creative – but I enjoy most of the talks and after a dozen years of attendance, I know a lot of the people in the crowd. This was the thread I created with the highlights from MKGN number 47:
    • A few days later, I headed down to London for the Windows Azure User Group Meetup. Unfortunately, I couldn’t use Node4’s London office, so I worked from the British Library and other locations for most of the day, before heading over to Elastacloud for the event in the evening. After Richard Conway (in/richardelastacloud) introduced the evening, Steph Locke (@TheStephLocke) from Microsoft talked about AI Landing Zones before Andy Cross (in/crossandy) gave a hilarious demonstration of how the death of coding is a little way off yet, even with multiple AI agents collaborating…
    • Towards the end of the month, I went to the inaugural NN1 Dev Club event, mostly to see what it’s about. I’m not a developer (though I might like to be…) and it seemed a good opportunity to get to know some of the tech folks in another nearby town. I enjoyed the talks – both PJ Evans (@MrPJEvans)’ tales of home automation (“Boiling Nemo”) and Dr Junade Ali (/in/junade)’s tales from the world of security research (“The Science of Software Engineering”) – so I’m sure I’ll be back for more events in future.

    In entertainment

    Cover image for The Silver Sword by Ian Serraillier

    When I was about 8 or 9, I read a book at school. I couldn’t remember much about it, except that it was about some children travelling across Europe, it was set in WW2, Warsaw was a part of it, and I really enjoyed it. I asked a group of friends if they remembered something like this and one asked ChatGPT. ChatGPT thought it might be The Silver Sword, by Ian Serraillier. I read the synopsis and that was it! Why I never thought to ask an AI, I have no idea, but it worked. I then had a very enjoyable few hours in the car listening to the audio book…

    On the subject of books, some more reading has arrived:

    This month’s TV has been about:

    • Explosive action (deliberate pun) Trigger Point, S2 (ITV).
    • Laid back and delightfully silly Detectorists, S2 (Netflix).
    • Stunning landscapes mixed with murder mystery Shetland, S8 (BBC).

    None are new, but they had been on the list for a while. The jury is still out on Shetland without Douglas Henshall in the main character role though.

    I’ve also decided that I need to get out to some gigs. My wife’s not into the electronic music that I enjoy so much and I was thinking about heading down to Greenwich with my youngest son for a Day with Chicane. Unfortunately the gig is 18+ and he will be 3 months short of adulthood, so maybe that will wait a while longer.

    In life: a trip to Tallinn

    The month started with a trip to Tallinn, Estonia. Nikki and I were celebrating 21 years of marriage and we had a fantastic weekend exploring a new city. As a country that’s been in and out of Soviet control several times in modern history we were not sure what to expect. What we found was a beautiful medieval city, food that seemed more Scandinavian than Eastern European, and public transport that was cheap and plentiful.

    Our hotel was only just outside the old town, which is a UNESCO World Heritage Site, so we didn’t actually need to use the transport much (the city is compact enough to walk). Even so, €2 each way for a bus to/from the airport seemed amazing value.

    Similarly, we ate and drank well at remarkably good prices compared with the UK – whether that was hot chocolate in Pierre Chocolaterie, hot wine in Ill Draakon (a medieval-themed bar), or one of the modern Estonian restaurants that we dined in. (For future reference, they were: Kaerajaan, Rataskaevu 16 and Pegasus). I came home thinking that, for the most part, the UK is a very dull and overpriced culinary destination.

    Other highlights were a visit to the top of the tower at the Niguliste Museum for views across the city. We also enjoyed a walk along the old town walls. Outside the old town, we took a short walk to Telliskivi and visited the photography exhibitions at Fotografiska.

    If you’re inspired by this and you fancy a trip to Tallinn (highly recommended), we flew with Wizz Air from London Luton and the Visit Tallinn website has a mine of information.

    Oh yes, and linking back to tech for a moment, I forgot that the delivery robots I see in Milton Keynes and Northampton have Estonian cousins…

    …and was amused to see people out and about experiencing virtual reality headsets in the centre of Tallinn…

    In life: a Welshman in Twickenham

    I may have been born in Northampton, but I identify as Welsh. And certainly when it comes to international Rugby Union, my team plays in red. I wasn’t going to say “no” though when I got the opportunity to watch England host Ireland at Twickenham. What a game! The final drop kick was at the other end of the pitch to me, but it was a brilliant match to be at.

    In life: sporty teens

    As ever, my sons are a huge part of what I get up to outside work. With Matt away in Spain, I was able to get to watch Ben play Hockey a bit more, including the Eastern Counties U17 tournament. Now Matt’s returned and he’s racing as much as he can, trying to get his Category 1 (and maybe Elite, if he can get enough points) road race licence. That needs my support sometimes (passing bottles, driving on the longer trips). At the other end of the scale, it was exciting to be able to watch him pick up a win at our local race:

    It’s fantastic to see the support he gets from his own teammates and some of the guys he’s racing against too (the video cuts off Richard Wiggins exclaiming “he’s got it!” just as I hit record). #ProudDad

    After a couple more races that I didn’t get to see (and didn’t exactly go to plan), he wrapped up the month with a particularly eventful weekend. On the Saturday, a couple of punctures meant his race only lasted a few minutes, but that was probably lucky as we then found the steerer tube at the top of his fork had a huge crack in it…

    That afternoon and evening, he rebuilt onto one of the spare cyclocross frames that were waiting to be set up, and then raced the Fakenham town centre crit’ on Sunday. It was a wet afternoon and my heart was in my mouth for the whole race but coming in third after an early break and leading for a good chunk of the race was a great result.

    Wrap-up

    That’s all for this month… please let me know what you think in the comments and I’ll be back in early May to recap on April… plus, hopefully, with extra time for some other posts in between.

    Weeknote 2024/09: radio; podcasts; AI and more

    Posted on By Mark Wilson

    This week’s weeknote is short. It’s also a little earlier than usual because today’s my wedding anniversary and I was busy trying to get everything wrapped up before flying away for the weekend…

    …so, in chronological order – but all mixed up between work and play:

    • Two weeks ago I said One Day (on Netflix) was a rom-com. Well… maybe not a comedy. A romantic drama? Regardless, we finished the series last weekend. There were tears. Mostly mine. And I highly recommend it for anyone who left uni’ in the UK in the 90s…
    • After passing my amateur radio foundation exam a couple of weeks ago, I have my callsign from Ofcom. I’m now M7OLN…
      • Last weekend, I met up with Christian Payne/Documentally (G5DOC) and talked radios among other things over an enjoyable cafe lunch…
      • I’m having trouble getting into local repeaters on a handheld radio from my place but we worked out my config issues so I know the radio is set up properly.
      • I can hear the local repeater but I need to put a better antenna up at home. That could be tricky. If only I could safely get closer to this chimney stack…
      • I’ve also ordered an antenna and window mount for the car. And discovered that there is a radio shop close enough to click and collect (Moonraker).
    • As a slight tangent from amateur radio (I can’t bring myself to call it HAM), I’ve discovered LoRa and some Meshtastic nodes are on their way. More on what that means when I have them set up…
    • I now have an identity on the Node4 Microsoft 365 tenant (don’t get me started on how difficult it is to bring multiple organisations into one but I have huge respect for my colleague who is managing this). Judging by the emails I’m receiving, I’m not the first person to have used this alias. I can deal with the emails for trainers and other fashion items… but it seems they were a Manchester United fan too, which is harder to take.
    • On Tuesday, I recorded a podcast with my colleague Bjoern (in/bjeorn-hirtenjohann). It was great fun and I was very chuffed when the producer, Beth, told me I could have a new career as a radio host. It may have been a joke but I would like to do more of this.
    • Then, I headed Bletchley for the Bletchley Park Microsoft AI User Group event. I was AI-jaded when I arrived. I was AI-buzzing when I left.
      • Will Rowe (@MSFTRecruit) made us laugh, a lot, at about recruiters.
      • I made some great connections.
      • I learned some cool things about AI prompting from Lydia Carroll (in/lydiacarroll) and about digital ecosystems from Chris Huntingford (@ThatPlatformGuy).
      • I also did some improv’ – volunteering for an unscripted, 1-2 minute talk on AI, that children would understand. Thanks to Stephanie Stasey (in/missai) for giving me the chance to get out of my comfort zone whilst practicing something I want to do more of – presenting.
    • I’ve also started to kick some thoughts around about what it means to be technical leader… and how I can encourage others.
    • And, in a discussion about recognition, someone who will remain anonymous shared this comment with me… I feel seen:

    “I’m also an introvert that overcompensates BTW. People confuse my enthusiasm, facilitation, and contribution as me being extrovert. Secretly I’m like a Duracell Bunny using a bad battery – it wears down quite quickly!“

    • (I was exhausted on Wednesday, after Tuesday’s exploits.)
    • Thursday ended with an example of when AI chatbots go wrong:
    • There were some blog posts not written this week that need to be:
      • My journey into amateur radio
      • Writing better AI prompts
    • Next week is looking even busier (with only 3 days at work) but I’ll try and write them soon.

    Right, time to go, I have a plane to catch.

    Not that many… I’m sure there will be more next week.
