CL332 - High Availability with Red Hat Enterprise Linux OpenStack Platform


Duration: 2 days

In this course, you will delve deeper into the high-availability features and tools than our Red Hat®OpenStack Administration (CL210) course.

This course uses the top open source clustering and high-availability solutions on the market and provides a comprehensive plan to connect them with Red Hat Enterprise Linux OpenStack Platform. Students will implement each of the services in a highly available manner and test failover scenarios. Students will use Pacemaker, Corosync, CMAN tools, and HAProxy to implement cluster and other high-availability tools.
