  • 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.
