Question: What is EC2 instance in aws?
An EC2 instance is a virtual server in Amazon's Elastic Compute Cloud (EC2) for running applications on the Amazon Web Services (AWS) infrastructure.

Question: What is volume in aws?
An Amazon EBS volume is a durable, block-level storage device that you can attach to a single EC2 instance.
You can use EBS volumes as primary storage for data that requires frequent updates, such as the system drive for an instance or storage for a database application.
