What is Load Balance?
Application Load Balancing is actually a rather simplistic technology at its core. It provides a unified connection point between the end users of an application and the application itself.
Throughput processing and the amount of secure transactions capable of being processed simultaneously are two key metrics that contribute to measuring the value of any Load Balancing solution. An additional and very important item to consider is the security functions that are bundled in. Since the design generally results in all client requests traversing the Load Balancer, it makes for an optimal place to consolidate other services such as pre-authentication, IPS and single sign-on.
