Cluster placement groups
A cluster placement group is a logical grouping of instances within a single Availability Zone. A cluster placement group can span peered VPCs in the same Region. Instances in the same cluster placement group enjoy a higher per-flow throughput limit for TCP/IP traffic and are placed in the same high-bisection bandwidth segment of the network.
Partition placement groups
Partition placement groups help reduce the likelihood of correlated hardware failures for your application. When using partition placement groups, Amazon EC2 divides each group into logical segments called partitions. Amazon EC2 ensures that each partition within a placement group has its own set of racks.
Spread placement groups
A spread placement group is a group of instances that are each placed on distinct racks, with each rack having its own network and power source.
Tag a placement group
To help categorize and manage your existing placement groups, you can tag them with custom metadata. For more information about how tags work, see Tag your Amazon EC2 resources .

Describe instances in a placement group
You can view the placement information of your instances using one of the following methods. You can also filter partition placement groups by the partition number using the AWS CLI.
