    • Tencent Cloud resources in different regions cannot access each other over the private network.
    • When purchasing Tencent Cloud services, we recommend selecting the region closest to your end users to minimize access latency .

    Availability Zone

    Availability zones (AZs) refer to Tencent Cloud's physical data centers that are in the same region. Each AZ is independently powered and have its own network resources. They are designed to ensure that failures within one AZ can be isolated from other zones, thereby ensuring service availability and business stability, excepting the occurrences of large-scale disasters or major power failures. AZs in the same region can communicate with each other over the private network, and products in the same AZ can access each other with a lower latency.
