Using Red Hat Enterprise Linux, it is possible to create highly available server clustering solutions able to withstand many common hardware and software failures with little or no interruption of critical services. By allowing multiple computers to work together in offering these critical services, system administrators can plan and execute system maintenance and upgrades without service interruption.

The chapters in this part guide you through the following steps in understanding and deploying a clustering solution based on the Red Hat Enterprise Linux Linux Virtual Server (LVS) technology:
