-- 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 @cluster@ placement group is a logical grouping of instances within a single Availability Zone that benefit from low network latency, high network throughput. A @spread@ placement group places instances on distinct hardware.
