TencentDB for SQL Server supports two types of networks: VPC and basic network.
Network Limitations
- Tencent Cloud services in the same region can communicate with one another over the private network.
- A CVM instance in a VPC can communicate with a TencentDB for SQL Server instance on the basic 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 basic 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 currently doesn't support public IP. If you need to use a public IP, you can use the port mapping function of SSH2 to connect to, configure, and manage an instance from the internet. For more information, see Connect to Instance.When purchasing TencentDB for SQL Server, it is 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.
