AWS EC2 Placement Groups Partition vs Spread

Question

Is there a good comparison table for the two types of AWS EC2 Placement Groups?

Answer 1

Partition Placement Group.

• Every partition in a PG has its own set of racks> All the racks have their network and powerhouse.
• There are mostly 7 partitions in each AZ. The number of instances in each partition is limited only by the account limits.
• Partitions can be in different AZs in the same region.
• Good for the large distributed workload.

Spread Placement Group

• Each instance is placed in its rack. Each rack has at most one instance.
• Good for deploying applications that have a smaller number of instances.
• The group can span multiple AZs in the same region.
