Load balancing refers to methods used to distribute network traffic amongst multiple hosts. This can be done by having different hosts used for different tasks (for example, separate servers for image and text content for a website) or by using a pool of redundant servers from which a load balancer can choose a single host to use for a given connection. Load balancing is usually achieved transparently to the client—that is, the service requested by the client appears to come from one place, even though it may be coming from multiple servers or a server at a different IP address.
