Course Description:
The Red Hat OpenShift Administration II: High Availability (DO380) course is a 5-day course that is designed to teach students how to build robust clusters that provide high availability and the ability to run large numbers of applications. Students will learn about OpenShift integration with datacenter infrastructure such as load balancers, identity management, monitoring, proxies, and storage. Students will also develop more troubleshooting and Day 2 operations skills in this course.
Additionally, students will design an OpenShift HA cluster, then build and test it. Students will use this cluster to examine more advanced topics in the administration and operation of a robust OpenShift cluster in the remainder of the course.

This was the class I needed.
The instructor Jeff took his time and made sure we understood each topic before moving to the next. He answered all of our questions, and I don't know about the rest of the students, but was very pleased with this experience.
I finally understand how to use Excel.
