This course helps you to understand high availability clustering by providing a strong concept and hands-on experience with Pacemaker and Corosync components of Red Hat / CentOS Enterprise High Availability Cluster. 

Also it is introducing you to other technologies, like ZFS storage to build more reliable environment for business.

It gives detailed steps of how to install cluster software packages, how to configure and administrate High Availability Cluster

It is preferred and directed to system administrators ( RHCSA  Level ).

The course will cover exactly the following read it carefully.

If you decided to take this course I need you to know that first chapter is a little bit long because in my opinion it is very important to understand the architecture of the lab so you can build it step by step. 

once you have a proper lab you will find practicing the cluster is so easy. So, I recommend you to be patient. If you feel it sounds boring you can skip it and go a head for next chapter.  

I expect if you reached this line that means you understood what will be covered in the course and it is crystal clear for you.
