Kubernetes is an open-source container orchestration platform that automates many of the manual processes involved in deploying, managing, and scaling containerized applications. You can cluster groups of hosts running Linux containers, and Kubernetes helps you easily, efficiently manage those clusters.It has a large, rapidly growing ecosystem. Kubernetes is not a traditional, all-inclusive PaaS (Platform as a Service) system. It can help you deliver and manage containerized, legacy, and cloud-native apps, as well as those being refactored into microservices.
