Task Amazon EC2 - Terminate Instance
The Amazon EC2 - Terminate instance Task terminates an EC2 instance. Termination is permanent — the instance and its root EBS volume are deleted. To preserve the EBS volume for later reuse, use Stop Instance instead.

Connection
To use Amazon EC2 Tasks you need to create an Amazon Connection first. Click the Settings icon to open the Manage Connections dialog.
