DRHCSUS05-BP02 Consider Amazon S3 for Outposts, or deploy a self-managed shared-file sharing solution

Amazon S3 for Outposts or EBS-backed shared storage solutions which are self-managed or procured from the AWS Marketplace can be used to reduce data duplication and overall storage consumption.

Desired outcome: Duplication of data will be minimized using local S3, managed, or self-managed shared storage services on Outposts

Benefits of establishing this best practice: Data duplication can be minimized, reducing overall storage requirements and energy consumption for on-premises data-residency workloads.

Level of risk exposed if this best practice is not established: Medium

Implementation guidance

AWS Outposts supports Amazon S3 for AWS Outposts, which can be used for on-premises shared object storage. The use of shared data provides data consistency and prevents the inefficient use of per-user or per-application data duplication. Where Amazon S3 for AWS Outposts is not deployed or is unsuitable for workload requirements, consider using self-managed or AWS Marketplace shared storage solutions that are compatible with Amazon Elastic Block Store (EBS) on Outposts volume-types as their backing storage.
