AWS recently introduced new features now customer is able to stop Amazon EC2 Spot Instances backed by Amazon EBS and start them at will, instead of relying on the “Stop” interruption behavior to stop your Spot Instances when interrupted. Earlier, customer can only terminate Spot Instances but now they can stop your Spot Instances and start them from the user initiated stop state provided Spot capacity is available within customer maximum price requirements.
The start/stop provides more control to customer over Spot Instances in addition to the existing interruption behavior. When you stop your Spot Instance, the EBS root device and attached EBS volumes are saved and their data persists. Upon restart, the EBS root device is restored from its prior state, previously attached data volumes are reattached, and the instance retains its instance ID.
This feature is available for persistent Spot requests. Customer will not be charged for instance usage while instance is stopped. Of course EBS volume storage is charged at standard rates. You should cancel your Spot request at any time to terminate stopped instances. This feature is only available for instances with an Amazon EBS volume as their root device.
