Can an External Server Access a GaussDB(for MySQL) Instance?

An Instance Bound with an EIP

For a GaussDB(for MySQL) 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 a GaussDB(for MySQL) instance.
• Create a GaussDB(for MySQL) instance and an ECS in the same VPC and access the GaussDB(for MySQL) instance through the ECS.
