EC2 Stop Instances

Stops an Amazon EBS-backed instance. You can use the Stop action to hibernate an instance if the instance is enabled for hibernation and it meets the hibernation prerequisites. For more information, see Hibernate your instance in the Amazon EC2 User Guide. We don't charge usage for a stopped instance, or data transfer fees; however, your root partition Amazon EBS volume remains and continues to persist your data, and you are charged for Amazon EBS volume usage. Every time you start your instance, Amazon EC2 charges a one-minute minimum for instance usage, and thereafter charges per second for instance usage. You can't stop or hibernate instance store-backed instances. You can't use the Stop action to hibernate Spot Instances, but you can specify that Amazon EC2 should hibernate Spot Instances when they are interrupted. For more information, see Hibernating interrupted Spot Instances in the Amazon EC2 User Guide. When you stop or hibernate an instance, we shut it down. You can restart your instance at any time. Before stopping or hibernating an instance, make sure it is in a state from which it can be restarted. Stopping an instance does not preserve data stored in RAM, but hibernating an instance does preserve data stored in RAM. If an instance cannot hibernate successfully, a normal shutdown occurs. Stopping and hibernating an instance is different to rebooting or terminating it. For example, when you stop or hibernate an instance, the root device and any other devices attached to the instance persist. When you terminate an instance, the root device and any other devices attached during the instance launch are automatically deleted. For more information about the differences between rebooting, stopping, hibernating, and terminating instances, see Instance lifecycle in the Amazon EC2 User Guide. When you stop an instance, we attempt to shut it down forcibly after a short while. If your instance appears stuck in the stopping state after a period of time, there may be an issue with the underlying host computer. For more information, see Troubleshooting stopping your instance in the Amazon EC2 User Guide.

Basic Parameters

Parameter	Description
AWS Region	Enter the desired AWS Region. If no Region is specified, and the requested service supports Regions, AWS routes the request to us-east-1 by default.
Force	Forces the instances to stop. The instances do not have an opportunity to flush file system caches or file system metadata. If you use this option, you must perform file system check and repair procedures. This option is not recommended for Windows instances. Default: false.
Hibernate	Hibernates the instance if the instance was enabled for hibernation at launch. If the instance cannot hibernate successfully, a normal shutdown occurs. For more information, see Hibernate your instance in the Amazon EC2 User Guide. Default: false.
Instance IDs	The IDs of the instances, space separated list. Input Example: i-1234e73f7ce83d7ae i-058ae73f7ce2345ae.

Advanced Parameters

Parameter	Description
Disable XML To JSON Auto Convert	When checked, XML responses are not automatically converted into JSON format.
Dry Run	Checks whether you have the required permissions for the action, without actually making the request, and provides an error response. If you have the required permissions, the error response is DryRunOperation. Otherwise, it is UnauthorizedOperation.
