Data Management Service (DMS) allows you to register a database instance in a third-party cloud by using a database gateway. When you register the database instance, no public endpoints are required and the database instance can be connected by using SSL connections.
Prerequisites
- Database Gateway is activated and a data gateway is created. For more information, see Create a database gateway.
Note When you create a database gateway, download the gateway program to the server on which the database instance is to be connected through the third-party internal network.
- The database instance is added to the created gateway. For more information, see Add databases.
- DMS is activated. For more information, see https://dms.aliyun.com.
- You are a DMS administrator or a database administrator (DBA) in DMS.
Background information
Enterprises and individual users who use a hybrid cloud may face the following challenges
in database management:
- If an Express Connect circuit is used to connect a database instance in a third-party cloud to a virtual private cloud (VPC), high costs are generated. This method is not suitable for small enterprises and individual users.
- If the public endpoint of the database instance is used for registration, the public endpoint is exposed to the Internet and the database instance may be attacked. This poses high risks if the database instance is in the production environment.
- Users need to forward service requests on their own. This makes the service less secure, less applicable, and not easy to use.
