Kubernetes is the gold standard in the world of container orchestration. It was originally created by Google, based on their experience of building and managing containers at scale ( at Google Scale). However its now driven by Cloud Native Compute Foundation ( CNCF), an open body, which also offers the official certification i.e. “Kubernetes Certified Administrator“. Kubernetes comes with mind boggling features, is very reliable, and extremely sophisticated container orchestration engine. It can let you convert your infrastructure into a Container as a Service (Platform), brining in some of the awe inspiring features such as Zero Down Time Deployments, Fault Tolerance, Auto Scaling, Cloud and Storage integrations, which were extremely difficult to implement. And it brings it to the masses with its truly open, lock in free eco system.
