What is AWS ELB?
The ELB stands for Elastic Load Balancer. It is a service provided by Amazon Web Services (AWS) that automatically distributes incoming web traffic across multiple Amazon Elastic Compute Cloud (EC2) instances. ELB can also automatically scale the number of instances to handle increases or decreases in traffic. This helps to ensure that the application remains available and responsive to user requests even under heavy load. It can be used to load balance HTTP/HTTPS traffic and TCP/SSL traffic.
