Can an External Server Access the GaussDB(for MySQL) Database?

An Instance Bound with an EIP

For an instance that has been bound with an EIP, you can access it through the EIP.

For details, see:

Connecting to a DB Instance over a Public Network

An Instance Not Bound with an EIP

• Enable a VPN in a VPC and use the VPN to connect to the GaussDB(for MySQL) instance.
• Create a GaussDB(for MySQL) instance and an ECS in the same VPC and access GaussDB(for MySQL) through the ECS.
