AWS provides a complete end to end robust full stack technology platform.
Core Network comprises of Regions, Availability Zones(AZ) and Edge Locations.
AWS has their own physical fiber network connecting the regions, AZs and most edge locations
Regions are geographically different locations.
Each region has at least 2 Availability Zones.
AZs can be used for setting up a high availability setup or be used as Disaster Recovery site(DR)
Edge locations are part of a CDN network that is used for caching static objects for faster content delivery.
