14// Starts an Amazon EBS-backed instance that you've previously stopped. Instances
15// that use Amazon EBS volumes as their root devices can be quickly stopped and
16// started. When an instance is stopped, the compute resources are released and you
17// are not billed for instance usage. However, your root partition Amazon EBS
18// volume remains and continues to persist your data, and you are charged for
19// Amazon EBS volume usage. You can restart your instance at any time. Every time
20// you start your Windows instance, Amazon EC2 charges you for a full instance
21// hour. If you stop and restart your Windows instance, a new instance hour begins
22// and Amazon EC2 charges you for another full instance hour even if you are still
23// within the same 60-minute period when it was stopped. Every time you start your
24// Linux instance, Amazon EC2 charges a one-minute minimum for instance usage, and
25// thereafter charges per second for instance usage. Before stopping an instance,
26// make sure it is in a state from which it can be restarted. Stopping an instance
27// does not preserve data stored in RAM. Performing this operation on an instance
28// that uses an instance store as its root device returns an error. For more
29// information, see Stopping instances
30// (https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/Stop_Start.html) in the
31// Amazon EC2 User Guide.
