Kubernetes

Kubernetes is an open-source platform for automating deployment, scaling, and management of containerized applications: you define the desired state in a declarative API (Pods, Deployments, Services, etc.), and controllers continuously reconcile reality to match it. It schedules containers across a cluster, handles service discovery and load balancing, performs rolling updates and rollbacks, manages configuration and secrets, and mounts storage via volumes. Kubernetes is highly extensible—Custom Resource Definitions (CRDs), Operators, and admission webhooks let teams add new APIs and policies—while its ecosystem (Helm, Kustomize, GitOps tools) provides repeatable, cloud-agnostic operations from laptops to multi-cloud.
