EUCPERF02-BP01 Identify geographic distribution of end users and design to minimize latency

When migrating to or implementing AWS EUC services, consider the location of each group of users with respect to the service endpoints for AWS WorkSpaces, WorkSpaces Applications, or WorkSpaces Secure Browser. You should deliver services from the Region with the lowest latency to most users.

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

Implementation guidance

Capture the location of each user group, and calculate the average latency between each group and their most proximal AWS Region that supports the required AWS EUC service. Due to Regional network routing and capabilities, it is possible the most proximal AWS Region does not necessarily offer the lowest latency.

If you must deploy AWS EUC services in a non-optimal Region (which is sometimes necessary to access other AWS services which have already been deployed), then be sure that you test your application to verify that they offer acceptable performance at the latency levels being experienced.

For an example of how latency might affect the user experience, see EUC latency trade-offs.
