[attachment=16509]
Linux Virtual Server Administration
Building a Linux Virtual Server (LVS) system offers highly-available and scalable solution for
production services using specialized routing and load-balancing techniques configured through
the PIRANHA. This book discusses the configuration of high-performance systems and services
with Red Hat Enterprise Linux and LVS for Red Hat Enterprise Linux 5.2.

Linux Virtual Server Overview
Linux Virtual Server (LVS) is a set of integrated software components for balancing the IP load
across a set of real servers. LVS runs on a pair of equally configured computers: one that is an
active LVS router and one that is a backup LVS router. The active LVS router serves two roles:
To balance the load across the real servers.
To check the integrity of the services on each real server.
