Load balancing allows incoming HTTP requests to a company's website to be distributed across several physical servers. If one server should fail, other servers can pick up the workload. Load balancing can be performed using application software. However, Bulwark Systems' dedicated switch can perform this function much faster as the redirection is handled by specialized hardware. With load balancing, clients access servers through a virtual IP address. The load balancer transparently redirects the requests with no change required on the clients or servers; all configuration and redirection is done on the load balancer.
