LVS (Linux Virtual Server) is a set of integrated software components for balancing IP load across real servers.
LVS runs on a pair of identically configured computers: one must be the active LVS router and the other the backup LVS router.
The active LVS router serves two roles:
- Balancing the load across the real servers
- Checking the integrity of the services on each real server
The backup LVS router monitors the active LVS router and takes over if the active LVS router fails.
