Amazon EC2 instance revert to the state in which it was created

Question

Is it possible to revert the AWS EC2 instance to the state at which it was created? If so how do I do it?

Answer 1

You can't revert a running instance back to the state it was when it was first spun up, but you can terminate the instance and spin up a new one in its place - this is assuming that 'state which it was created' is one of the AMI's available to you in AWS.

If you have a custom configuration that you would occasionally like to revert to (i.e. with your custom settings, data, software installed on it), the way to do that is spin up an instance - get it configured exactly the way you want it to be and then save the running instance as a private AMI - then whenever you want to revert to that state, delete your running instance and create a new one using your custom 'base' AMI.
