- Auto Scaling dynamically adds and removes EC2 instances, while Elastic Load Balancing manages incoming requests by optimally routing traffic so that no one instance is overwhelmed.
- Auto Scaling helps to automatically increase the number of EC2 instances when the user demand goes up, and decrease the number of EC2 instances when demand goes down
- ELB service helps to distribute the incoming web traffic (called the load) automatically among all the running EC2 instances
- ELB uses load balancers to monitor traffic and handle requests that come through the Internet.
Using ELB & Auto Scaling
- makes it easy to route traffic across a dynamically changing fleet of EC2 instances
- load balancer acts as a single point of contact for all incoming traffic to the instances in an Auto Scaling group.
