- Regions provide multiple, physically separated and isolated Availability Zones which are connected with low latency, high throughput, and highly redundant networking.
- Availability Zones offer highly availability, fault tolerance, and scalability.
- Consist of one or more discrete data centers, each with redundant power, networking, and connectivity, housed in separate facilities.
- An Availability Zone is represented by a region code followed by a letter identifier; for example, us-east-1a.
- An AWS Local Region is a single datacenter designed to complement an existing AWS Region.
- Edge locations are locations where end users access services located at AWS.
