Explanation: It is always possible that someone can terminate an EC2 instance using the Amazon EC2 console, command line interface or API by mistake. If the admin wants to prevent the instance from being accidentally terminated, he can enable termination protection for that instance. The user can also setup shutdown behavior for an EBS backed instance to guide the instance on what should be done when he initiates shutdown from the OS using Instance initiated shutdown behavior. If the instance initiated behavior is set to terminate and the user shuts off the OS even though termination protection is enabled, it will still terminate the instance.
