What are AWS Local Zones and Wavelength Zones, and what specific use cases do they address?

Intermediate

Answer

AWS Local Zones extend AWS infrastructure closer to large population centers that are not close to a full AWS Region, providing single digit millisecond latency for latency sensitive applications like gaming or media production in that specific metropolitan area, while Wavelength Zones embed AWS compute and storage directly within telecommunications providers' five G networks, enabling extremely low latency applications like augmented reality that need to avoid the delay of traffic traveling all the way back to a traditional AWS Region.
aws ec2 describe-availability-zones --filters Name=zone-type,Values=local-zone
Real-world example A media production company in a major city without a nearby full AWS Region uses a Local Zone to run its latency sensitive video editing application, achieving performance nearly identical to running the workload in a traditional on premises data center within that same city.
