Kubernetes is open-source container-orchestration software for deploying, managing, and scaling containers. When applications are packaged with their dependencies and settings in a container, a tool is required to automatically manage and scale the containers based on the demand for access to the application and Kubernetes is the right tool to do it.
As applications grow and are deployed across multiple servers, Kubernetes can control how and where those containers run. With Kubernetes, users can easily scale their application horizontally while monitoring and maintaining container health.
Kubernetes also offers the possibility of portability, deploy applications in containers from different local development machines, quality control services, and other stages until production. The tool also has a wide collection of extensions and plugins that add more power.
