There are two types of load balancing available, Network Load Balancing (NLB) and Hardware Load Balancing.
Network Load Balancing distributes IP traffic across multiple cluster hosts. It also ensures high availability by detecting host failures and automatically redistributing traffic to the surviving hosts.
Hardware Load Balancing is a physical unit that directs computers to individual servers in a network, based on factors such as server processor utilization, the number of connections to a server, or the overall server performance.
Typically load balancing is employed between two or more web servers to ensure that the incoming requests/queries are evenly distributed to avoid latency, enhance performance and increase availability.
