OpenShift is a free, open-source, and cloud development Platform as a Service (PaaS) developed by Red Hat that allows the developers to develop and deploy their applications on a cloud infrastructure. It is a community distribution of Kubernetes and enables faster development and release cycles for applications. It comes with a simple and easy to use web interface that allows you to monitor the container resources, container health, the nodes the containers reside on, IP addresses of the nodes, etc.
