As someone who has worked in software since 2001, and in the Cloud Native (containerisation and Kubernetes) space since 2013, I'm getting old enough to have seen trends come and go a few times. VMs came (and stayed), continuous integration went from a fad talked about by gurus to the mainstream of software delivery, and containers went from some changes Google made to the Linux kernel to the de facto standard for software packaging, and then on to the foundation for Kubernetes, an industry-standard software deployment platform.

As Cloud Native consultants, we often get asked about managing cloud costs. The business that doesn’t ever want to save money is a rare one indeed.

Now that interest rates have returned to normal, investors are asking questions about whether their money might return more in a bank than being spent on rented IT infrastructure. A recent estimate of cloud spend in tech-related industries claimed that 3 ..read more

At EngineerBetter we’ve evaluated four self-hosted CI systems in order to compare them against each other: Jenkins, Concourse, Tekton and Argo Workflows. For each CI system we’ve created some pipelines that ..read more

Version 7 of Cloud Foundry’s cf CLI is now generally available. This makes rolling deployments a first-class feature, and adds many more flexible workflows than the original cf push offered. These changes bring the Cloud Foundry user experience more in line with what users have come to expected from Kubernetes’ Deployments. Rolling deployments are now available - so why should you switch? A History of cf push Over the last 18 months, the Cloud Controller (the brains of Cloud Foundry) has been extended to support a new set of APIs - collectively known as V3 ..read more
