Who Needs Load Balancing?

Server Load Balancing Review: "Large enterprises, 'mission-critical' Web sites who demand maximum uptime and server performance and others can benefit from load balancing solutions. Service providers who need the ability to deploy additional servers quickly and transparently to users, and Web sites which experience bursts of high-traffic also benefit from multiple servers in a clustered environment.
For Web site owners who desire near 100% uptime, higher availability, redundancy, scalability - load balancing user-requests is a very effective solution. "
