OpenShift as a Container Platform and Why Operators Matter
This post is part of a series on OpenShift as a platform. We’re looking at the container foundation here, specifically what OpenShift adds on top of upstream Kubernetes and how Operators turn that into an extensible platform for everything else we’ll cover. Kubernetes is the Engine Kubernetes is the most widely adopted container orchestration system in the world, and OpenShift is built on top of it.
