Elastic Load Balancing Overview

What is Load Balancing?

Load Balancer: Server or set of servers behind the scenes that will forward traffic that is received to multiple servers(e.g. EC2 instances) downstream

Ex. Three EC2 instances exist > Fronted by an elastic load balancer -> Three users directly connecting to elastic load balancer
-Each user has its load being sent, be load balanced, and would be connected to one backend EC2 instance respectively
-More users = More the load is going to be balanced across EC2 instance
-Users do not know which backend instance they are connected to.
Just know they have to connect to your elastic load balancer which gives one end point of connectivity only
