TL;DR Best practice gets encoded into industry leading software (and that happens more quickly with SaaS applications). So if you’re not using the latest software, or if you’re customising it, then you’re almost certainly divergent from best practices, which slows things down, makes it harder to hire and train people, and creates technology debt. Background […]

What are Modern Applications?
TL;DR Modern Apps use Platforms, Continuous Delivery, and Modern Languages. Or more specifically, Modern Apps are written in Modern Languages, get deployed onto Platforms, and that deployment process is Continuous Delivery (as these things are all interconnected). Background ‘Modern Apps’ seems to be a hot topic right now. Some of my DXC colleagues are getting […]

Stateful Serverless
For a little while I’ve been maintaining a FaaS on Kubernetes list to track the many implementations of Functions as a Service running on top of Kubernetes. Today brings CloudState as the first addition in a little while, and it’s quite an interesting one for a variety of reasons. Knative I became aware of CloudState […]

The PCF K8s flip-flop
I’m starting to see companies abandon Pivotal Cloud Foundry (PCF) in favour of Kubernetes distributions such as Red Hat’s OpenShift; and it’s almost certainly just a matter of time before we see traffic in the opposite direction. My suspicion is that this is nothing to do with the technology itself[1], but rather that early implementations […]

TL;DR VMs on public cloud don’t provide the same level of control over sizing as on premises VMs, and this can have a number of impacts on how capacity is managed. Most importantly ‘T-shirt’ type sizing can provide sub optimal fit of workload to infrastructure, and the ability to over commit CPUs is very much […]
