Course overview

Deploy reliable and available mission-critical services in a highly available cluster.

In the Red Hat High Availability Clustering (RH436) course, you will learn how to provide highly available network services for mission-critical enterprise environments through the deployment and management of shared storage and server clusters. The course is designed for experienced Linux system administrators and has a strong focus on practical laboratory work.

You will configure a cluster of systems running the Pacemaker component of the Red Hat Enterprise Linux High Availability Add-On and deploy Linux-based services such as web servers and databases in the cluster. The course also covers storage components from the Resilient Storage Add-On, where installations and applications that require multiple cluster nodes can have simultaneous access to the same storage. This includes Shared Volume Groups in Logical Volume Manager (LVM), Red Hat Global File System 2 (GFS2), and Device-Mapper Multipath.

The course is based on Red Hat Enterprise Linux 8.3.
