Cloud zone

Google and AWS both use regions as a way to provide cloud services to customers.

In cloud computing, a cloud region is a geographic area that contains multiple cloud zones, while a cloud zone is a logical data center within a region

Google uses zones to provide data center services and every region will have at least 3 zones.

Google Cloud and AWS both have points of presence (PoPs) located in many more locations around the world.

Concept	Google Cloud	Amazon Cloud
Data center cluster	Region	Region
Abstracted data center	Zone	Availability Zone
Edge caching	Points of Presence	Points of Presence
Min zones	Three	Two

Google Cloud uses points of presence to provide Cloud CDN and to deliver built-in edge caching for services such as App Engine and Cloud Storage.

AWS uses points of presence to provide the content delivery network service, Amazon CloudFront, and for edge caching services like Lambda at the edge.
