Kubernetes (K8s) is a system that automatically deploys applications to different web connected computers or hosts. It helps to manage the performance of applications among many different computers. The Kubernetes system is open source and is usually set up in a cloud service like AWS or Azure.
Kubernetes automatically addresses applications that fail and scales support for containers that share out an operating system between applications. Kubernetes actually orchestrates a container platform named Docker. Relativity makes use of Kubernetes.
