Kubernetes is the leading orchestrator for distributing container instances across multiple physical nodes. The nodes are managed by the Kubernetes control plane, a collection of components which maintain the cluster’s state, respond to changing conditions, and handle scheduling decisions. It’s essential to understand the control plane’s role when you’re operating clusters that need consistent availability. In this article, you’ll learn what happens when the control plane fails so you can plan ahead and implement protections....

If you aren’t familiar with BonziBuddy, that probably sounds pretty weird to you…but the backstory behind this weird relic of the aughts is even stranger than the monkey himself....
