Peering Connection Overview

Last Updated At: 2025-11-11 17:51:13

Introduction

Peering Connection is a high-bandwidth and high-quality cloud resource interconnection service that helps you establish communication links among cloud resources. Peering connections can be used across multiple regions, multiple accounts, and multiple types of heterogeneous networks, which can easily implement complex network scenarios, such as 2-region-3-center and one server shared by game players. It enables interconnection between VPCs, allowing you to deploy different businesses.

VPC peering connection is a cross-VPC network interconnection service used for synchronizing office data. It enables interconnection between two VPCs as if they were on the same network. After routing policies are configured at both ends, interconnection is enabled between VPCs of the same user or different users in the same region or across regions. Peering connection does not depend on any separate hardware. Therefore, no single points of failure and bandwidth bottlenecks will occur in a peering connection.

Strengths

Peering connection service has the following strengths over Internet transmission transmission.

  • Higher Quality

    • Using the same self-built private network with group businesses, the peering connection is not affected by the quality of public network providing significantly better availability, latency, and packet loss rate.
  • Enhanced Security

    • Protected by DDoS Security of the Anti-DDoS basic system, the peering connection offers high defense capabilities.
    • Avoiding wide-area Internet and ISP links, the peering connection minimizes the risk of data theft during public network transmission.
