Examples of com.amazonaws.services.ec2.model.StartInstancesRequest

com.amazonaws.services.ec2.model.StartInstancesRequest
Container for the parameters to the {@link com.amazonaws.services.ec2.AmazonEC2#startInstances(StartInstancesRequest) StartInstances operation}.
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.

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.
