What is a Load Balancer?
Load balancing or load distribution is the balancing of a workload amongst multiple computers/servers, so it provides a single internet service such as a website from multiple servers. Some load balancers also support databases.
Why use Load Balancing?
Load balancing is used to achieve optimal resource utilization, maximize throughput, minimize response time, avoid overload and increase reliability through redundancy. Load balancing is needed if the traffic of a website is too great for one server to cope with. It will also mean a website does not have a single point of failure, as if one server goes down the other server(s) will take the load as the server will fail over.
