Kubernetes started as a simple container orchestration tool but has evolved into a universal control plane that abstracts infrastructure for application teams, using etcd as its core database to manage desired states, self-healing, and jazz-like improv. The platform is designed to be flexible and durable enough to allow users to use it in unexpected ways, with primitives like controllers, replica sets, deployment, stateful sets, and custom resource definitions that can be layered on top of each other like Lego blocks. Kubernetes operators bring domain-specific control over workloads, allowing for the adaptation of existing systems into the platform, while looking towards the future, level-triggered systems will start controlling more than just software systems.
