  • AWS Placement Group is a logical grouping of instances within a single Availability Zone

Limitations:

  • Supports only specific enhanced networking instance types
  • Can be configured within Availability zone only. Can not spane across multiple availability zone.
  • Placement Groups cannot be merged. Instances in one placement group should be terminated, and then relaunched into an other placement group
  • can’t move an existing instance into a placement group
  • Recommend using the same instance type for all instances in a placement group.
  • Network traffic to and from resources outside the placement group is limited to 5 Gbps.
