The AWS Cloud spans 55 Availability Zones within 18 geographic Regions and 1 Local Region around the world, with announced plans for 12 more Availability Zones and four more Regions in Bahrain, Hong Kong SAR, Sweden, and a second AWS GovCloud Region in the US.

Region = AWS Regions provide multiple, physically separated and isolated Availability Zones which are connected with low latency, high throughput, and highly redundant networking. Each Region Consists two or more availability zones. Regions are selected  to satisfy performance requirements like low latency and to satisfy specific regulatory requirements.
Availability Zones (AZs) = Availability Zones offer AWS customers an easier and more effective way to design and operate applications and databases, making them more highly available, fault tolerant, and scalable than traditional single datacenter infrastructures or multi-datacenter infrastructures.

AWS Local Region = For customers who specifically need to replicate their data or applications over greater geographic distances, there are AWS Local Regions. An AWS Local Region is a single datacenter designed to complement an existing AWS Region. Like all AWS Regions, AWS Local Regions are completely isolated from other AWS Regions.

Edge Location = It is the location where end users are located to access services. This uses AWS CloudFront to offer the services to end users with low latency. Amazon CloudFront uses a global network of 136 Points of Presence (125 Edge Locations and 11 Regional Edge Caches) in 62 cities across 29 countries.
