Have you ever faced challenges migrating to a new version of a Kubernetes cluster?
What if you also had to:
Implement new security policies? Switch your CNI plugin? Migrate to a different Service Mesh solution? From my experience, such changes are often met with hesitation and are frequently postponed. Coordinating migrations and updates with all development teams can be incredibly challenging.
I believe it’s time to rethink how we approach infrastructure management.
A few years ago, I started reflecting on the benefits of Infrastructure as Code (IaC). It led me to an idea: if infrastructure is code, why not deploy it using a canary strategy, just as we do with applications?
Today, we have all the necessary technologies to spin up parallel Kubernetes-based infrastructure and seamlessly migrate even stateful services to the new environment. In case of issues, it’s also possible to roll back without disruption.
I strongly believe this approach can significantly accelerate the adoption of changes, boosting both team productivity and application performance.
What are your thoughts on this approach? Have you tried anything similar in your projects? Or do you see potential challenges? Let’s discuss—your insights might inspire others to rethink their strategies as well!
