             If you specify one or more instance IDs, Amazon EC2 returns
             information for those instances.
            
             If you do not specify instance IDs, Amazon EC2 returns information
             for all relevant instances. If you
             specify an invalid instance ID, a fault is returned.
            
             If you specify an instance that you do not own, it will not be
             included in the returned results.
