Explanation:
A placement group is a logical grouping of instances within a single Availability Zone. Using placement groups

groups are recommended for applications that benefit from low network latency, high network throughput, or
both.http://docs.aws.amazon.com/AWSEC2/latest/UserGuide/placement-groups.html
