Using DTS, you can synchronize databases between different deployment forms such as local IDC, Tencent Cloud, and other third-party cloud vendors. This facilitates database migration, database backup, and building a hybrid cloud architecture with active-active deployment for enterprise users.
The DTS is part of the Tencent Cloud Network. If you use DTS for database synchronization, it's necessary to connect the networks where the source/target databases reside with the Tencent Cloud Network to which DTS belongs, ensuring DTS can connect to the source/target databases.
Choosing DTS Assess Type
The method chosen to connect the source/target database with the Tencent Cloud for DTS determines the access type selected when the DTS task is configured.
Note:
Adding DTS IP address to the security group or the allowlist of the interfacing database may pose certain security risks. Users are advised to enhance security measures during use, such as standardizing account password management, using authentication methods for internal API communications, inspecting and restricting unnecessary network segments, etc. Using DTS indicates you acknowledge the potential risks. If high security is a concern, it's recommended to choose Direct Connect, VPN Access, or VPC connections.
After using DTS, we recommend that you delete the DTS IP address from the security group or firewall promptly.
The database can be accessed through the public network IP.
The public network cannot guarantee transmission bandwidth and poses security risks, making it suitable for scenarios with low transmission requirements.
Add DTS IP address to the database allowlist.(For self-built databases, it is usually configured in the firewall; for other cloud vendor databases, it is configured in security groups.)
VPN Access
The database is interconnected with Tencent Cloud VPC through VPN connections.
VPN connection uses encrypted transmission with a certain bandwidth guarantee, meeting most network transmission security requirements.
The database is interconnected with Tencent Cloud VPC through Direct Connect.
When Direct Connect is used, network links are dedicated to users, with no risk of data leakage, high security, and meet the high-level network connection requirements for users such as financial institutions and governments.
