How Do I Configure a Security Group to Enable Access to GaussDB Instances?

When you attempt to connect to a GaussDB instance through a private network, check whether the ECS and GaussDB instance are in the same security group.
- If the ECS and GaussDB instance are in the same security group, they can communicate with each other by default. No security group rule needs to be configured.
- If the ECS and GaussDB instance are in different security groups, you need to configure security group rules for them, separately.
  - GaussDB instance: Configure an inbound rule for the security group with which the DB instance is associated.
  - ECS: The default security group rule allows all outbound data packets. In this case, you do not need to configure a security rule for the ECS. If not all outbound traffic is allowed in the security group, you need to configure an outbound rule for the ECS to allow all outbound packets.
When you attempt to connect to a GaussDB instance through an EIP, you need to configure an inbound rule for the security group associated with the DB instance.
