Load Balancing

Load balancing is a method used to distribute computer network traffic between multiple endpoints.

Various criteria can be used to distribute traffic between end-points, like turn-based, weighted or persistent routing, to name a few. The load balancing device or software, called a load balancer, sits between the pool of backend servers and the clients, ensuring that the client gets routed to the most desirable backend server.

Health monitors are used to ensure that the traffic is only sent to healthy backend servers by taking the faulty server out of the load balancing pool. This provides the optimal experience for clients.
