  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.
