Overview
To use Direct Connect, users need to purchase a Tencent Cloud VPC and Direct Connect gateway, apply for Direct Connect, and connect the local IDC database to the Tencent Cloud VPC through nearby access, then transfer data via DTS.
DTS supports using the local IDC database as the source/destination for data transmission. The following example scenario is Local IDC Database (Direct Connect) -> Tencent Cloud Database (Database).
Establishing Network Interconnection Through Direct Connect
DTS Task Configuration
1. Purchasing a DTS Task
When purchasing a DTS task, select the Tencent Cloud VPC1's region as Source Instance Region, that is, region A. Select the region where the target database is located as Target Instance Region, that is, region B.
2. Configuring DTS Task
In source database settings, select Direct Connect as Access Type, select VPC1 as VPC, and select one of its subnets Subnet1. In target database settings, select Database as Access Type.
3. Connectivity Test
If the database and its associated network have configured security access rules, such as security groups, firewall, IP access restrictions, etc., it is necessary to allow DTS IP address, otherwise, connectivity test may fail.
Allowing DTS IP Address
1. When the connectivity test fails, follow the instructions in the popup to access DTS IP address.
2. Sequentially check if the database has set the following network rules, and if so, allow DTS IP address in the corresponding rules.
Check if the database-associated network layer has set network ACLs or security groups.
Check if the server layer where the database resides has set up a firewall (e.g., iptables rules for Linux systems).
Check if the source database layer has set IP access restrictions.
