Regions and AZs

    Regions

    Overview

    A region is the physical location of an IDC. In Tencent Cloud, regions are fully isolated from each other, ensuring cross-region stability and fault tolerance. We recommend that you choose the region closest to your end users to minimize access latency and improve access speed.

    Characteristics

    • The networks of different regions are fully isolated. Tencent Cloud services in different regions cannot communicate via a private network by default.
    • Tencent Cloud services in different VPCs can communicate each other over Cloud Connect Network which is fast and stable.

    Availability Zones

    Overview

    An availability zone (AZ) is a physical IDC of Tencent Cloud with independent power supply and network in the same region. It can ensure business stability, as failures (except for major disasters or power failures) 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.

    Characteristics

    Tencent Cloud services in the same VPC are interconnected via the private network, which means they can communicate using private IPs, even if they are in different availability zones of the same region.

    Note:

    Private network interconnection refers to the interconnection of resources under the same account. Resources under different accounts are completely isolated on the private network.
