Container for the parameters to the {@link com.amazonaws.services.ec2.AmazonEC2#describeInstances(DescribeInstancesRequest) DescribeInstances operation}.
The DescribeInstances operation returns information about instances that you own.
If you specify one or more instance IDs, Amazon EC2 returns information for those instances. If you do not specify instance IDs, Amazon EC2 returns information for all relevant instances. If you specify an invalid instance ID, a fault is returned. If you specify an instance that you do not own, it will not be included in the returned results.
Recently terminated instances might appear in the returned results. This interval is usually less than one hour.
