Red Hat OpenShift Administration III: Scaling Deployments in the Enterprise

Impact

Course description

The Red Hat OpenShift Administration III: Scaling Deployments in the Enterprise (DO380) course expands on the required skills to plan, implement, and manage OpenShift® clusters in the enterprise. You learn how to configure and manage OpenShift clusters at scale to address increasing and special demands from applications and to ensure reliability, performance, and availability.

This course is based on Red Hat® OpenShift Container Platform 4.22.

Business Outcome 

Organizations that run a growing number of Red Hat OpenShift clusters lose time and money when administrators repeat day-2 configuration by hand on every cluster, workloads consume expensive specialized nodes they do not actually need, and when clusters cannot meet enterprise requirements for identity, audit retention, and application recovery. This course prepares IT operations teams to automate cluster configuration by using OpenShift GitOps, and to partition capacity so that critical and specialized workloads get the nodes that they need.  Teams also learn to integrate clusters with corporate identity and security information and event management (SIEM) systems, and to recover applications after data loss. These capabilities enable organizations to scale with customer demand while reducing manual rework and shortening recovery time.

 Student Outcome 

After completing this course, students can operate production OpenShift clusters at scale by partitioning nodes into pools with the Machine Configuration Operator and special-purpose operators, and schedule only the intended workloads onto those pools, and integrate enterprise LDAP and OpenID Connect (OIDC) identity providers, including direct authentication with an external OIDC provider. Students can also automate cluster configuration and application deployment with OpenShift GitOps, troubleshoot performance and availability with OpenShift monitoring, deploy and query logging with forwarding to external log aggregators and SIEM systems, and configure application-level backups with OpenShift APIs for Data Protection (OADP).
