Organizational Transformation Impact

This course is intended to develop the skills needed to manage Red Hat OpenShift clusters and support containerized applications that are highly available, resilient, and scalable. Red Hat OpenShift is an enterprise-hardened application platform based on Kubernetes that provides a common set of APIs and abstractions that enable application portability across cloud providers and traditional data centers. Red Hat OpenShift adds consistency and portability of operational processes across these environments and can also be deployed as a managed service. A Red Hat SRE team shares the responsibility of managing Red Hat OpenShift clusters with a customer’s IT operations team when using a managed OpenShift offering such as Red Hat OpenShift on AWS (ROSA) or Azure Red Hat OpenShift (ARO).

Individual Growth Impact

Acquire the expertise to execute pivotal tasks expected of OpenShift cluster administrators across on-premises, cloud-based, and vendor-managed clusters. This includes the activation of add-on operators, adept management of multi-tenant permissions for diverse roles, and the configuration of applications necessitating privileged access to both cluster and host resources.
