It is a component used to balance network traffic across multiple EC2 and ECS instances within multiple availability zones.

I will limit the scope to EC2 instances load balancing in this chapter. ELB allows you to achieve a greater level of fault tolerance and higher availability. The beauty of this service is, it scales its request...
