EC2 Placement Group

Hello,

No, having a single partition in an EC2 placement group is not the same as using a cluster Partition. I believe with a single partition, your all instances would end up on the same segment without any isolation and that will not provide the full benefit of true partitioning or fault isolation.

Hello,

1. Cluster groups give you low-latency communication over hardware isolation while Spread groups isolate instances at the rack level.
2. Partition groups isolate instances at a more minute hardware component level like racks, switches and power. This provides a benefit of failure isolation and intra-partition communication performance.
