Have you heard of Kubernetes (also known as k8s)? Until a few months back, I knew it existed and that it was like infrastructure’s holy grail. It has to cover the basics, like auto-scaling and load balancing or automated rollbacks… And then there are millions of tools to build on top of it.

It also feels nice to do that on the 10th anniversary of “Kubernetes: The Future of Cloud Hosting” MeteorHack’s blog post.

Please keep in mind that a Kubernetes cluster is an extremely complex beast, and I’m pretty far from being able to explain all the “whys” you may have. Our amazing DevOps Engineer managed to make it work, and I’m really happy with the current setup. Both because the app performs better at a lower cost and because I learned a lot along the way.

Kubermatic Kubernetes Platform is in an open source project to centrally manage the global automation of thousands of Kubernetes clusters across multicloud, on-prem and edge with unparalleled density and resilience.
