Answer: Elastic Load Balancing and Auto Scaling
Elastic Load Balancing (ELB) automatically distributes incoming application traffic across multiple targets, such as Amazon EC2 instances, containers, and IP addresses, and can handle the varying load of your application traffic in a single Availability Zone or across multiple Availability Zones. Auto Scaling ensures that you have the correct number of Amazon EC2 instances available to handle the load for your application.
