Outline for this course

Introduction to high availability

Define how high availability can secure and improve Red Hat Enterprise Linux OpenStack Platform services.

Deploying a high-availability cluster

Configure Pacemaker, Corosync and HaProxy for the OpenStack API services.

Configure Red Hat Enterprise Linux OpenStack Platform services

Install Red Hat Enterprise Linux OpenStack Platform and configure the API services.

Implement an active-passive MySQL cluster

Connect the MySQL database with the highly available architecture.

Implement an active-active Qpid broker

Set up and run a pool of message brokers to improve availability and reliability.

Testing the environment

Run a unit test protocol for every service, and review and validate the high-availability services.

Running failure scenarios

Fail various services and test high availability.

Implement an even more highly available cloud

Explore innovative ways to secure your cloud data using top open source clustering solutions like MariaDB Galera and GlusterFS, a Red Hat community storage project.
