What is an Elastic IP Address?

Amazon provides an Elastic IP Address with an AWS account. An Elastic IP address is a public and static IP address based on IPv4 protocol. It is designed for dynamic cloud computing.
This IP address is reachable from the Internet. If we do not have a specific IP address for our EC2 instance, then we can associate our instance to the Elastic IP address of our AWS account. Now our instance can communicate on the Internet with this Elastic IP Address.
