A region is the physical location of an IDC. In Tencent Cloud, different regions are fully isolated, ensuring cross-region stability and fault tolerance. When purchasing Tencent Cloud services, we recommend selecting the region closest to your end users to minimize access latency and improve download speed.
Regions have the following characteristics:
An availability zone is a physical IDC of Tencent Cloud with independent power supply and network resource in a single region. It can ensure business stability, as failures (except for large-scale disaster or major power failure) in one AZ are isolated without affecting other AZs in the same region. By starting an instance in an independent availability zone, users can protect their applications from being affected by a single point of failure.
Availability zones have the following characteristics:

When selecting a region and availability zone, you need to consider the following factors:
Actions such as the use and viewing of cloud disks are availability zone and region-specific. To easily migrate data and services to other regions or construct a cross-region disaster recovery system, you can copy snapshots to other regions. For more information, see Cross-region Snapshot Replicating.
