Network Connection Instructions
Last updated: 2025-12-24 14:59:00
TDMQ for Apache Pulsar supports both private and public network access, with connection requirements varying depending on the network type.
Connection Method Description
Connection Method | Connection Description | Reference Documentation |
Private Network Connection | If the client and the Pulsar cluster are deployed within the same Virtual Private Cloud (VPC), they can communicate over the private network by default, without requiring any additional configuration. | |
| If the client and the Pulsar cluster are deployed in different VPCs, since VPCs are logically isolated from each other, they cannot communicate directly. To enable cross-network communication, you can use Cloud Connect Network (CCN) to achieve VPC interconnection across different regions under the same account. | |
Public Network Connection | A dedicated public network route needs to be established, allowing clients to connect to the Pulsar cluster over the public network. Since public networks are accessible from any network environment, security policies need to be configured to ensure secure connections. | |
Normally, it is recommended that you prioritize private network access to achieve lower network latency, higher transmission bandwidth, and better security isolation, especially for core businesses in production environments. Public network access can be enabled when necessary, for example, when your service needs to be publicly accessible or during development and debugging from public networks. When public network access is enabled, it is recommended that you configure an allowlist policy to strictly restrict access by IP addresses to ensure data security.
Security Group Requirements
Ensure that the security group for your test program allows TCP traffic on ports 6000-7000 (communication ports) and 8080 (the addressing port for routing access). For specific steps, see Creating a Security Group.
