Network Environment

Last updated: 2020-07-02 14:03:28

    TencentDB for SQL Server supports two types of network environments: VPC and classic network.

    Network Restrictions

    • Tencent Cloud services in the same region can communicate with each other over the private network.
    • A CVM instance in a VPC can communicate with a TencentDB for SQL Server instance on the classic network in a different AZ in the same region only after a subnet is configured and a VPC IP is assigned.
    • Tencent Cloud services on the classic network in different regions cannot communicate with one another over the private network. They can communicate across VPCs only after a peering connection is configured.
      Currently, TencentDB for SQL Server doesn't support public IP. If you need to use a public IP, you can use the port mapping feature of SSH2 to connect to, configure, and manage an instance from the internet. For more information, please see Connecting to Instance.

      When purchasing TencentDB for SQL Server, you are recommended to select the same region as your CVM instance to reduce access delay.

    Network Connectivity Test

    The network connectivity test tool provided on the TencentDB for SQL Server purchase page can be used to check whether there are CVM instances in the selected region/AZ and network type that can communicate with TencentDB for SQL Server over the private network.

    Click View Details to view the information of eligible CVM instances, including ID/instance name, AZ, configuration (CPU, memory, disk, and network), and master IP address. You can also use the search function to quickly determine whether a specific CVM instance can communicate with TencentDB for SQL Server over the private network.
