EC2 placement groups

When you deploy a fleet of instances that are processing transactions in a distributed manner, you sometimes need to control the placement of the instances in the underlying architecture to allow for certain specific application requirements. You can use placement groups to control this behavior.

Cluster placement groups

You can use the cluster placement groups to group instances together in a configuration to allow for very low network latency. Cluster placement groups allow for the non-blocking, non-oversubscribed, fully bi-sectional nature of the connectivity, meaning that instances in a placement group will be able to utilize the full line rate of 10 GBps to talk to each other. To place instances in...
