Learn more about the high-availability features and tools of Red Hat Enterprise Linux OpenStack Platform.
High Availability for Red Hat© Enterprise Linux© OpenStack© Platform (CL332) is for system administrators and cloud operators interested in high availability for Red Hat Enterprise Linux OpenStack Platform. This course provides a deeper dive 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.


  • Deep knowledge of OpenStack services and their connectivity.
  • Understanding of high-availability concepts and high-availability implementations.


Target Audience:

Linux system administrators and cloud administrators interested in, or responsible for, maintaining a private cloud. Cloud operators interested in providing high availability for their cloud. RHCE certification or requisite level of knowledge is highly recommended.


Course Objectives:

  • High-availability basic concepts
  • Comprehensive plan for a highly available cloud
  • Cluster a Red Hat Enterprise Linux OpenStack Platform environment using high-availability designs and implementations
  • Validation of the highly available cloud
  • MariaDB Galera cluster for Red Hat Enterprise Linux OpenStack Platform database
  • GlusterFS for Glance and Cinder
