Resilience in AWS Wavelength

AWS recommends that you architect edge applications in a hub and spoke model with the Region providing the most scalable, resilient, and cost effective options for components that are less latency sensitive, that need to be shared across Zones, or that have states that need to persist. Then, use Wavelength Zones for the application components that need low latency, data residency, higher bandwidth, or increased quality of service over 5G mobile networks.

If you need to replicate your data or applications in a Wavelength Zone, AWS recommends that you use an Availability Zone in the Region that is not the parent zone as the failover zone. In the following example, the parent Availability Zone is Availability Zone A, so the resources are replicated to Availability Zone B.
