LVS: Method
OES implements local load balancing using LVS plus additional monitoring tools to deliver a full management suite.
Procedure 1. Hypothetical Service Transaction
- The first time a user accesses the web site, she will access the load balancing LVS router.[1]
- The LVS router will direct the connection to the least busy available server.
- The server will perceive the connection as a standard Internet connection and it will service the connection as usual. In this example, all communications are transparently routed through the load balancer.
Redundant LVM Routers
In practice, multiple LVS servers are used in a failover mode for redundancy; however, the conceptual protocol is the same.
