KEMP Technologies, Inc. Server load balancer (SLB)
Server load balancers are designed to distribute Layer 4 traffic load between two or more servers, network links, CPUs, hard drives, or other resources, in order to get optimal resource utilization, throughput, or response time. Load balancers use multiple load balancing algorithms to direct user traffic and provide high-availability configurations to increase reliability through redundancy.
