Fractional AI & Cloud Platform Architect. AI agent platforms, MLOps, Kubernetes, and cloud-native delivery by Charlie Holland. Senior expertise, no permanent hire.https://www.hollandtech.nethttps://www.hollandtech.net/the-bottleneck-was-never-typinghttps://www.hollandtech.net/the-bottleneck-was-never-typingWhat a company really spends its money on is the gathering: getting everyone pointed the same way, getting a decision to actually happen, getting one change past four teams and out of the door. More work has always meant more people, and more people has always meant more gathering. A working sheepdog doesn't obey that arithmetic. One dog and one handler move several hundred sheep, and another thousand sheep doesn't mean another thousand dogs. That ratio is the thing AI could finally break, and almost nobody is building for it yet.Sat, 15 Aug 2026 00:00:00 GMThttps://www.hollandtech.net/the-angels-share-of-every-productivity-gainhttps://www.hollandtech.net/the-angels-share-of-every-productivity-gainEvery year, roughly 2% of the whisky in every cask in Scotland breathes out through the wood and is gone. Nobody fights it. The angels' share, they call it, the price of letting the stuff mature at all. The economy runs the same trick on productivity, except our angels get greedier every year. Which is why Keynes promised your grandparents a fifteen-hour week and you're reading this between two meetings about a third.Mon, 13 Jul 2026 00:00:00 GMThttps://www.hollandtech.net/we-traded-efficiency-for-flexibilityhttps://www.hollandtech.net/we-traded-efficiency-for-flexibilityThere's a lump of granite off the Ayrshire coast that used to be a volcano. Sixty million years of weather wore it down to the one part hard enough to matter, and we've made the world's curling stones out of it ever since. Software does the opposite. Nothing ever erodes, every layer you've ever shipped is still down there needing somebody to mind it, and you pay for all of it in headcount and meetings. Oh, Fred Brooks, save us all.Tue, 30 Jun 2026 00:00:00 GMThttps://www.hollandtech.net/getting-it-out-of-their-headshttps://www.hollandtech.net/getting-it-out-of-their-headsEvery enterprise technology programme for forty years has been the same project: getting what people know out of their heads and into a system. AI is just the first tool sharp enough to reach the knowledge we always called too skilled to automate. Here's what the rising water does when it finally reaches the high ground, and why I help build the thing that worries me.Fri, 12 Jun 2026 00:00:00 GMThttps://www.hollandtech.net/you-dont-get-autonomous-agents-on-day-onehttps://www.hollandtech.net/you-dont-get-autonomous-agents-on-day-oneThe board has seen the demo and wants the autonomous agent live by Q3. That is not how any of this works. Here is the map I actually use to deliver AI: where it goes, and how to reach it without becoming one of the 40% of projects that get cancelled.Thu, 11 Jun 2026 00:00:00 GMThttps://www.hollandtech.net/fifteen-hyperdisks-per-node-gkehttps://www.hollandtech.net/fifteen-hyperdisks-per-node-gkeYou size a GKE cluster for thirty small stateful workloads, each with a modest PVC. You expect them to pack onto the nodes neatly. Instead half the nodes are idling, a quarter of your pods are Pending, and the error is about 'volume attach limits.' The number, when you dig into it, is fifteen. Why fifteen? Good question.Fri, 24 Apr 2026 00:00:00 GMThttps://www.hollandtech.net/can-you-build-ragshttps://www.hollandtech.net/can-you-build-ragsEighteen months ago, a senior exec at a global consulting firm asked me whether we could build RAGs. His customers were banging down the doors. The question is quietly awkward now — and most people still asking it don't actually need what they think they're asking for.Tue, 14 Apr 2026 00:00:00 GMThttps://www.hollandtech.net/what-are-customers-saying-aws-billhttps://www.hollandtech.net/what-are-customers-saying-aws-billYou put your AI agent in a container. You put the container in Kubernetes. You added network policies and RBAC. Then an exec asked it to build a sentiment analysis model and it escalated its way through your entire cloud account. Here's exactly how.Wed, 08 Apr 2026 00:00:00 GMThttps://www.hollandtech.net/contain-a-thing-that-knows-how-to-escapehttps://www.hollandtech.net/contain-a-thing-that-knows-how-to-escapeAgentic AI on your laptop is one thing — worst case it trashes your machine. But enterprises want it in the cloud, at scale, pointed at everything. The problem isn't the power. It's the containment. And this thing is smart enough to read the blueprints of its own cage.Tue, 07 Apr 2026 00:00:00 GMThttps://www.hollandtech.net/claude-is-not-your-architecthttps://www.hollandtech.net/claude-is-not-your-architectSomewhere between 'ask Claude for a quick opinion' and 'Claude is writing our Jira tickets,' we lost the plot. AI agents are brilliant implementers. They're also confidently wrong about every decision that matters. And when it all falls over, they won't be the ones carrying the bag.Mon, 06 Apr 2026 00:00:00 GMThttps://www.hollandtech.net/claude-code-forrest-gumphttps://www.hollandtech.net/claude-code-forrest-gumpAI agents will get you to dev-done at record speed — right up until you realise you're miles past the actual problem. 80% of projects still spend 80% of their time at 80% complete. Agents don't fix that. They just help you reach it sooner.Wed, 25 Mar 2026 00:00:00 GMThttps://www.hollandtech.net/ai-is-not-realityhttps://www.hollandtech.net/ai-is-not-realityYour exec promised a customer that AI would 'just know' the answer to any question across every database in the org. It won't. AI is a model of reality — and there's always a gap. The question is whether you know what it is.Tue, 10 Mar 2026 00:00:00 GMThttps://www.hollandtech.net/cloud-architects-personal-shoppershttps://www.hollandtech.net/cloud-architects-personal-shoppersToo many architecture reviews are just debates about which vendor's service logo to put on the diagram. The real value of an architect is knowing when the menu is the wrong starting point.Wed, 18 Feb 2026 00:00:00 GMThttps://www.hollandtech.net/devops-bubble-burstinghttps://www.hollandtech.net/devops-bubble-burstingWe never really needed ten thousand DevOps engineers. The market's not dying — it's clearing out the noise. When the dust settles, the builders will still be here.Sat, 10 Jan 2026 00:00:00 GMThttps://www.hollandtech.net/kubeflow-to-vertex-ai-migrationhttps://www.hollandtech.net/kubeflow-to-vertex-ai-migrationGoogle says Vertex AI is the managed future of ML on GCP. They're probably right. But the migration from self-hosted KubeFlow is 6-12 months of real work, not the 2-sprint effort that the consultants estimated.Mon, 15 Dec 2025 00:00:00 GMThttps://www.hollandtech.net/hippos-steve-jobs-reality-checkhttps://www.hollandtech.net/hippos-steve-jobs-reality-checkThe Highest Paid Person's Opinion isn't always wrong — but it needs a reality check from the people who actually build things. The best organisations make space for 'cool idea, but here's how that actually works.'Fri, 05 Dec 2025 00:00:00 GMThttps://www.hollandtech.net/vpc-service-controls-gcp-painfulhttps://www.hollandtech.net/vpc-service-controls-gcp-painfulVPC Service Controls prevent data exfiltration from GCP projects. Simple concept. Brutal consequences.

Daily check-ins. Hand-holding. Scrum built the perfect assembly line — and AI loves assembly lines. The question isn't whether AI can do the tickets. It's whether your team is more than the sum of its tickets.Wed, 15 Oct 2025 00:00:00 GMThttps://www.hollandtech.net/stop-calling-freelancers-mercenarieshttps://www.hollandtech.net/stop-calling-freelancers-mercenariesThe 'missionaries vs mercenaries' framing is lazy and wrong. After 30 years of freelancing, I've seen full-timers who don't care and contractors who bleed for the outcome. It's not about employment status — it's about who gives a damn.Wed, 20 Aug 2025 00:00:00 GMThttps://www.hollandtech.net/serverless-at-scale-honest-takehttps://www.hollandtech.net/serverless-at-scale-honest-takeA thousand tiny Lambda functions scattered everywhere with no ownership, no contracts, and no way to test them locally. Sound familiar? Here's when serverless works, when it doesn't, and the discipline most teams skip.Thu, 12 Jun 2025 00:00:00 GMThttps://www.hollandtech.net/ops-in-a-frockhttps://www.hollandtech.net/ops-in-a-frockPipeline jockeys cranking YAML. Firefighting teams on endless rota. Developers throwing features over the wall. Call it SRE, call it Platform Engineering — if nobody owns production, it's just ops in a frock.Tue, 08 Apr 2025 00:00:00 GMThttps://www.hollandtech.net/ai-gold-rush-selling-shovelshttps://www.hollandtech.net/ai-gold-rush-selling-shovelsAI-enabled revenue feels a lot like tulip bulbs in 1637. Everyone's hoarding data by the petabyte, hoping it'll bloom into gold. But most of it's weeds — and the only ones smiling are the lads selling shovels.Wed, 05 Feb 2025 00:00:00 GMThttps://www.hollandtech.net/kubernetes-operators-abstraction-that-workedhttps://www.hollandtech.net/kubernetes-operators-abstraction-that-workedMost Kubernetes abstractions add complexity for complexity's sake. Operators are the exception — they encode operational knowledge into software and turn 'file a ticket and wait three days' into 'apply a YAML file and get a database in two minutes.'Wed, 15 Jan 2025 00:00:00 GMThttps://www.hollandtech.net/five-year-gig-long-fractional-engagementhttps://www.hollandtech.net/five-year-gig-long-fractional-engagementMost contracts last three to six months. I spent five years as a part-time architect at a century-old industrial manufacturer. Here's what long-term fractional engagement really looks like — the advantages, the risks, and why it's the antithesis of mercenary behaviour.Sun, 10 Dec 2023 00:00:00 GMThttps://www.hollandtech.net/acquisition-nobody-planned-forhttps://www.hollandtech.net/acquisition-nobody-planned-forPost-merger tech consolidation is one of the most expensive, least glamorous problems in enterprise IT. Nobody talks about it because it's not sexy. But it's where careers go to die and budgets go to evaporate.Fri, 15 Sep 2023 00:00:00 GMThttps://www.hollandtech.net/shift-left-security-sounds-greathttps://www.hollandtech.net/shift-left-security-sounds-greatEveryone preaches 'find vulnerabilities earlier.' The concept is sound. The execution is usually a disaster — every build fails on day one, exception lists grow longer than vulnerability lists, and security becomes a rubber stamp that makes everyone feel safe without actually being safe.Sat, 10 Sep 2022 00:00:00 GMThttps://www.hollandtech.net/azure-devops-pipelines-nobody-loveshttps://www.hollandtech.net/azure-devops-pipelines-nobody-lovesAzure DevOps Pipelines is the CI/CD system enterprise teams end up with because they're an Azure shop. Not because they evaluated the options. Not because they love it. Because it was already there.Mon, 15 Aug 2022 00:00:00 GMThttps://www.hollandtech.net/hardware-companies-building-softwarehttps://www.hollandtech.net/hardware-companies-building-softwareWhen a century-old manufacturer tries to 'go digital,' the cultural collision is spectacular. Manufacturing thinks in years and certifications. Software thinks in sprints and experiments. The smart money respects both.Mon, 20 Jun 2022 00:00:00 GMThttps://www.hollandtech.net/eks-vs-aks-vs-gke-productionhttps://www.hollandtech.net/eks-vs-aks-vs-gke-productionMost Kubernetes comparisons are feature matrices written by people who've read the docs. This is what the three major managed Kubernetes services actually feel like when you're running production workloads, handling upgrades at 2am, and arguing with IAM policies.Sun, 10 Apr 2022 00:00:00 GMThttps://www.hollandtech.net/kubeflow-twelve-months-of-painhttps://www.hollandtech.net/kubeflow-twelve-months-of-painAfter a year of running KubeFlow across multiple client deployments, I can confidently say: the platform that promises end-to-end ML on Kubernetes delivers end-to-end frustration instead. Here's the post-mortem.Mon, 10 Jan 2022 00:00:00 GMThttps://www.hollandtech.net/terraform-won-get-over-ithttps://www.hollandtech.net/terraform-won-get-over-itThe Infrastructure as Code wars are over. Terraform won. And yet enterprise teams are still clinging to vendor-native tooling like ARM templates and CloudFormation because 'it's supported by the vendor.' Supported doesn't mean good.Sun, 05 Dec 2021 00:00:00 GMThttps://www.hollandtech.net/big-vendor-builds-your-pochttps://www.hollandtech.net/big-vendor-builds-your-pocVendor consultants optimise for showcasing their platform's capabilities, not for your team's ability to maintain it. They build reference architectures, not products. The demo passes. Production doesn't.Sat, 20 Nov 2021 00:00:00 GMThttps://www.hollandtech.net/microk8s-ml-at-the-edgehttps://www.hollandtech.net/microk8s-ml-at-the-edgeNot everyone can 'just use the cloud.' Healthcare data sovereignty, air-gapped networks, public sector paranoia — sometimes you're deploying ML inference on a rack server in a basement. Here's what that actually looks like with MicroK8s.Tue, 10 Aug 2021 00:00:00 GMThttps://www.hollandtech.net/ml-platform-science-fair-projecthttps://www.hollandtech.net/ml-platform-science-fair-projectEvery organisation wanted an MLOps platform circa 2020. Most had data scientists running Jupyter notebooks on their laptops and calling it a pipeline.

They're running different things on different clouds and calling it a strategy. Multi-cloud is what happens when nobody's in charge.Sat, 20 Mar 2021 00:00:00 GMThttps://www.hollandtech.net/helm-vs-kustomize-pick-onehttps://www.hollandtech.net/helm-vs-kustomize-pick-oneI've deployed Kubernetes manifests with both Helm and Kustomize across half a dozen enterprise clients. The debate is tiresome. They solve different problems. Here's when each one actually makes sense.Thu, 05 Nov 2020 00:00:00 GMThttps://www.hollandtech.net/elastic-stack-on-kuberneteshttps://www.hollandtech.net/elastic-stack-on-kubernetesECK just went GA and we're running Elasticsearch on Kubernetes in production. It works. It's also the most operationally demanding thing in the entire cluster, and we spend more time babysitting it than everything else combined.Wed, 10 Jun 2020 00:00:00 GMThttps://www.hollandtech.net/istio-service-mesh-nobody-asked-forhttps://www.hollandtech.net/istio-service-mesh-nobody-asked-forEveryone adopted Istio because everyone else was adopting Istio. Complex, resource-hungry, and solving problems most teams didn't have — it was the poster child for resume-driven development.Sun, 15 Mar 2020 00:00:00 GMThttps://www.hollandtech.net/service-fabric-orchestrator-that-losthttps://www.hollandtech.net/service-fabric-orchestrator-that-lostService Fabric got a lot right — stateful services, the actor model, rolling upgrades with health checks. But it lost the ecosystem war to Kubernetes, and being technically superior wasn't enough to save it.Fri, 15 Nov 2019 00:00:00 GMThttps://www.hollandtech.net/gitops-before-it-had-a-namehttps://www.hollandtech.net/gitops-before-it-had-a-nameWe were using FluxCD to reconcile Kubernetes state from git before anyone called it GitOps.

The secret to coming out unscathed is to back open technologies, think carefully about IaaS vs PaaS, and not get locked in while the giants fight it out.Mon, 11 Jun 2018 00:00:00 GMThttps://www.hollandtech.net/iteration-and-agilityhttps://www.hollandtech.net/iteration-and-agilitySince the 1950s we've been looking for better ways to build software.
