What Are Regions and AZs?

Regions and availability zones (AZs) are typically used to describe the locations of data centers. You can create resources in specific regions and AZs.

• A region is a physical data center location. Each region operates independently, enabling maximum fault tolerance and stability. Once a resource is successfully created, its region cannot be changed.
• An AZ is a physical location where resources use independent power supplies and networks. Within a single region, there can be multiple AZs that are physically isolated from each other yet interconnected through internal networks. This ensures the independence of each AZ while offering cost-effective, low-latency network connectivity.
