I'm looking for a way to have some kind of ephemere instances of Amazon EC2.
The idead would be to
- launch an instance
- do some work on it
- reboot the instance (not stopping)
- reset the hard disk to it's default state.
How can I do the latest step using Amazon mechanisme (or other ideas if this is not possible)?
I want to do that because I would like to reset the state of the instance several time by hour without having to pay for a full hour each time. In Amazon you have to pay for a minimum of one hour each time you start an instance. I would like to be able to reset the instance to the initial state because the instance will be used by untrusted users that will have access to a not very secure application. I would like to be able to reset the instance each time a user logout. Only one user at a time will have access to the instance.
