Method	Scenario	Default Port	Description
Connecting to a GeminiDB HBase Instance over a Private Network	Your applications are deployed on an ECS that is in the same region and VPC as your instances.	2181	High security and performance If the ECS and GeminiDB HBase instance are in the same security group, they can communicate with each other by default. No security group rule needs to be configured. If they are in different security groups, configure security group rules for them, separately. Configure inbound rules of a security group for the GeminiDB HBase instance by following Setting Security Group Rules for a GeminiDB HBase Instance. The default security group rule allows all outbound data packets, so you do not need to configure a security rule for the ECS. If not all access from the ECS is allowed, you need to configure an outbound rule for the ECS.
