ec2-start-instances
Description
Starts an instance that uses an Amazon EBS volume as its root device.
Instances that use Amazon EBS volumes as their root devices can be quickly stopped and started. When an instance is stopped, the compute resources are released and you are not billed for hourly instance usage. However, your root partition Amazon EBS volume remains, continues to persist your data, and you are charged for Amazon EBS volume usage. You can restart your instance at any time. Each time you transition an instance from stopped to started, we charge a full instance hour, even if transitions happen multiple times within a single hour.
Note
Before stopping 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.
Performing this operation on an instance that uses an instance store as its root device returns an error.
You cannot start or stop Spot Instances.
For more information, see Using Amazon EBS-Backed AMIs and Instances.
The short version of this command is ec2start.

Deprecated Options
For a limited time, you can still use the private key and X.509 certificate instead of your access key ID and secret access key. However, we recommend that you start using your access key ID (-O, --aws-access-key) and secret access key (-W, --aws-secret-key) now, as the private key (-K, --private-key) and X.509 certificate (-C, --cert) won't be supported after the transition period elapses.
