Overview

This course prepares OpenShift cluster administrators to manage Kubernetes workloads and to collaborate with developers, DevOps engineers, system administrators, and SREs to ensure the availability of application workloads. This course focuses on managing typical end-user applications that are often accessible from a web or mobile UI and that represent cloud-native and containerized workloads. It also covers how to deploy and update application dependencies, such as databases, messaging, and authentication systems.
