ApsaraDB RDS supports two types of endpoints: internal endpoints and public endpoints. By default, you are provided with an internal endpoint that is used to connect to your ApsaraDB RDS for SQL Server instance. If you want to connect to your RDS instance over the Internet, you must apply for a public endpoint.
Internal and public endpoints
Apply for or release a public endpoint
- Go to the Instances page. In the top navigation bar, select the region in which the RDS instance resides. Then, find the RDS instance and click the ID of the instance.
In the left-side navigation pane, click Database Connection.
Apply for or release a public endpoint.
If you have not applied for a public endpoint, you can click Apply for Public Endpoint.
If you have applied for a public endpoint, click Release Internet Address.
When you apply for a public endpoint, Add 0.0.0.0/0 to the whitelist is selected by default. The 0.0.0.0/0 CIDR block indicates that all IP addresses are allowed to access your RDS instance. We recommend that you add this CIDR block only for a connectivity test. When you run online workloads, do not add this CIDR block to an IP address whitelist.
In the message that appears, click OK.
