Notes on Load Balancers.

Load balancing refers to efficiently distributing incoming network traffic across a group of backend servers, also known as a server farm or pool. Modern, large scale, high traffic websites like google serve millions of concurrent requests from users or clients and to cost effectively scale to meet these high volumes, multiple servers are often employed to distribute the incoming traffic efficiently. Load Balancers acts as the “traffic cop” sitting between the multitudes of servers and the clients, routing client requests across all servers capable of fufilling those requests in a manner that maximizes speed and capacity utilization and above all else, ensures that no server is overworked, which could degrade performance.
