DRHCSUS05-BP01 Consider using supported AWS-managed file services to minimize data duplication in Local Zones

Shared file services can be implemented using AWS managed file services, AWS marketplace offerings, or even self-managed solutions to minimize data duplication for your data-residency workloads.

Desired outcome: Duplication of data is minimized using managed or self-managed shared storage services in Local Zones.

Benefits of establishing this best practice: Data duplication and overall storage consumption can be minimized to reduce energy utilization and support your sustainability objectives.

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

Implementation guidance

A growing number of AWS Local Zones now support Amazon FSx for Windows File Server and Amazon FSx for Lustre. These managed shared-file services can be used to efficiently store and share data between large numbers of data residency workloads, minimizing the environmental costs of duplicating data for individual workloads or users. While choosing a Local Zone, review the Local Zone feature matrix to determine if these services are available in location that meets your data residency requirements.

If Amazon FSx services are not available in the Local Zone you choose, consider using self-managed or AWS Marketplace shared storage solutions for Windows SMB or NFS shares to minimize the duplication or movement of data within the Local Zone.
