vDBS service flexibly supports a variety of connection models, depending on customer needs. Basically, there are two main connection models: Public and Private connections.

– For Private connection model: Database is deployed inside a VPC Network. Only resources within this VPC can access the Database via Private IP.

– For Public connection model: The database will be provided with an additional Elastic IP allowing access from outside the VPC Network.

To use vDBS service with public connection to transmit data, customers need to configure the Database to be safely accessible from the Internet. Steps:

Step 1:Initialize Database Instance with Public connection model

During the Database initialization process, in the “Public Access” section, select Yes to ensure the Database can be accessed from the Internet.

After successful initialization, the Database Instance will be automatically assigned an Elastic IP address. Customers use this IP address to make public connections from the Internet.

Step 2:Configure Security for Database Instance

Set up Security Group: Adjust the Security Group of the Database to allow connections from necessary IPs. Customers should:

– Only open the Database port (usually port 3306 for MySQL, 5432 for PostgreSQL,…).

– Restrict Source IP to only trusted or necessary IP addresses to enhance security.

Step 3:Test and Connect

After configuration, use Elastic IP (Public Address) to connect to the correct port of the Database.
