Cloud Infrastructure - Load Balancer

Load Balancer

A load balancer allows you to evenly distribute traffic to multiple servers in one or datacentre. If a datacentre or server becomes unavailable (unhealthy) the load balancer will route the traffic to only available datacentres with servers. 

Load Balancer is very important infrastructure component which runs in front of every service to mange and route traffic load.

Load balancer is used for scalable and available solutions.
