Instance Connection Methods

GaussDB(for Cassandra) supports databases connections over public and private networks.

Table 1 Connection methods

Method

Scenario

Description

Private network

A private IP address is provided by default.

Your applications are deployed on an ECS that is in the same region and VPC as your instances.

High security and performance

Public network

If you cannot access a DB instance through a private IP address, bind an EIP to the DB instance first and connect the ECS to the DB instance through the EIP.
  • Low security
  • For faster transmission and improved security, you are advised to migrate your applications to an ECS that is in the same subnet as your instance and use a private IP address to access the instance.
