Abstract:

Load balancing increases the reliability of a web site by routing requests to other servers in the cluster when one of the servers is too busy or fails. There are many techniques for achieving load balancing. There is an approach to load balancing modern web applications that does not require any load-balancing hardware, and handles failure of servers more gracefully than round-robin DNS.
