Kubernetes as a Universal Control Plane
summary
Kubernetes is framed as a distributed-systems kernel whose core is Kubernetes is a database: etcd stores desired state (spec) and actual state (status) and the API server mediates all changes. Controllers (scheduler, kubelet, replica sets, deployments, statefulsets) run reconciliation loops to make relentless forward progress, yielding self‑healing clusters. Extensibility via custom resource definitions plus operators adapts databases and services to the dynamic model; CSI, taints/tolerations and pod disruption budgets are production‑ready building blocks that already work at scale.
