AWS Outposts is a fully managed service that extends AWS infrastructure, AWS services, APIs, and tools to virtually any datacenter, co-location space, or on-premises facility for a truly consistent hybrid experience. Amazon Elastic Compute Cloud (Amazon EC2) placement groups allow you to influence the placement strategy of instances on the underlying hardware. You can select from cluster, spread or partition placement strategies, depending on the needs of the workload.

With Amazon EC2 placement groups on Outposts, you can now use the spread and partition placement strategies to improve the resilience of workloads configured for high availability. A spread placement group places each instance of the group on a distinct rack to reduce correlated failures. A partition placement group distributes instances across logical partitions such that groups of instances in one partition do not share a rack with instances of a different partition.

Amazon EC2 placement groups on Outposts are available to all Outposts customers at no additional cost in all AWS Regions where Outposts is supported today. For more information about EC2 spread placement groups, visit our documentation.
