/#Action=CreatePlacementGroup

http://ec2.{region}.amazonaws.com/#Action=CreatePlacementGroup

Creates a placement group in which to launch instances. The strategy of the placement group determines how the instances are organized within the group. A <code>cluster</code> placement group is a logical grouping of instances within a single Availability Zone that benefit from low network latency, high network throughput. A <code>spread</code> placement group places instances on distinct hardware. A <code>partition</code> placement group places groups of instances in different partitions, where instances in one partition do not share the same hardware with instances in another partition. For more information, see <a href="https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/placement-groups.html">Placement groups</a> in the Amazon EC2 User Guide.
