DRHCSUS01-BP01 Choose the Local Zone anchored to the Region that best aligns with your sustainability goals if more than one meets your data-residency requirements
It may be possible to evaluate and choose an AWS Local Zone that is anchored to a more sustainable AWS Region when there are several which meet your data residency requirements.
Desired outcome: Services are deployed to the Local Zone anchored to the most sustainable parent AWS Region.
Benefits of establishing this best practice: You can choose an AWS Local Zone that is anchored to a more sustainable AWS Region to support your sustainability objectives.
Level of risk exposed if this best practice is not established: Medium
Implementation guidance
AWS Local Zones are always anchored to a parent AWS Region where
control plane functions and the full set of AWS services are
made available for building solutions. When considering a Local
Zone for data residency use cases, there may be only one that
meets your requirements. However, there may be times where more
than one Local Zone can be used, each anchored to different
parent Regions. When this is the case, select an
AWS Region based on sustainability
