Introducing Spread Placement Groups for Amazon EC2

Spread placement groups help reduce the likelihood of failures within clusters or groups of instances. Amazon EC2 has had cluster placement groups, which enable applications to get the low-latency network performance necessary for tightly-coupled node-to-node communication typical of many HPC applications. Now with spread placement groups, member instances will be placed on distinct hardware, reducing the impact of hardware failures on your applications.

Spread placement groups are available in all AWS regions. To get started, visit the AWS Management Console, AWS Command Line Interface (CLI), and AWS SDKs.
