Lvs Load balancer VIP
LVS(Linux Virtual Server) - LVS is an open source project that was started way back in 1998, with the primary focus of building high availability, and load balancing solutions using clusters made up of commodity hardware. VIP or Virtual IP address is the address that is added as an A record for the service that the virtual cluster provides.
Linux Virtual Server - Glossary. Commonly used terms include the following: LVS director: load balancer that receives all incoming client requests for services and directs them to a specific "real server" to handle the request. Real servers: nodes that make up an LVS cluster which are used to provide services on the behalf of the cluster.
