com.amazonaws.services.ec2.model.DescribeInstancesRequest

Represents a placement group into which multiple Amazon EC2 instances can be launched. A placement group ensures that Amazon EC2 instances are physically located close enough to support HPC features, such as higher IO network connections between instances in the group.
