Can you attach the root volume of one instance to another instance and make that as the root volume

Yes, you can attach the root volume of one Amazon EC2 instance to another, and make it the root volume of the new instance, but it requires some steps and careful consideration. This process involves detaching the root volume from the original instance, attaching it to the new instance, and potentially making adjustments to the new instance's boot configuration to ensure it uses the attached volume as the root.

What is the difference between AMI and snapshot

An Amazon Machine Image (AMI) is a template for creating EC2 instances, containing the operating system, software, and configuration needed to launch a virtual server. A snapshot, on the other hand, is a point-in-time copy of an EBS volume, essentially a backup of the data stored on that volume.

If you terminate an EC2 instance that was used to create an AMI, what happens to the AMI?
