In their own words
Kubernetes
Kubernetes is an open-source system for automating deployment, scaling, and management of containerized applications. It supports stateless, stateful, and data-processing workloads, and can run locally, in a cloud, or in a datacenter; users can also choose a managed service rather than operate a cluster themselves. It coordinates gradual updates while monitoring application health and can roll back a change if something goes wrong. Pods receive IP addresses and groups of Pods can share a DNS name, with load balancing across them. Kubernetes can mount storage from local, public-cloud, or network systems such as iSCSI or NFS. Secrets and configuration can be updated without rebuilding images. Scaling can be manual or automatic based on CPU use. Security mechanisms include Secrets, Pod security standards, RuntimeClasses, network policies, admission controllers, and audit logging. Kubernetes is free, with a listed plan price of free. It does not include application-level services such as databases, message buses, caches, or cluster storage systems.
