Peering

Peering is an interconnection service that connects two VPCs for data synchronization. The two VPCs connected act like one VPC, and transfer data to each other based on routing policies. The two VPCs can belong to the same account or different accounts and can reside in the same region or different regions. Peering is independent from hardware, and is therefore free from single points of failure and bandwidth bottlenecks.

Quick Start

Benefits

Flexible Configuration

A cross-region peering connection supports at least 1 Mbit/s bandwidth, meeting diversified service demands.

High Reliability

Peering provides secure and reliable interconnection between VPCs. Independent from hardware, Peering is free of single points of failure and bandwidth bottlenecks and can meet the requirements of geo-disaster recovery.

Easy Management

Peering is easy to configure and takes effect immediately.

Features

Disaster Recovery Deployment

A local peering connection allows applications to run between VPCs in the same region. A cross-region peering connection supports geo-disaster recovery by connecting VPCs in different regions. You can quickly deploy a geo-disaster recovery solution where three data centers are deployed across two regions.

High-Availability Connection

A cross-region peering connection supports bandwidth from 1 Mbit/s to several Mbit/s with less than 0.2% packet loss rate and more than 99.95% availability. Peering also provides point-to-point network latency SLA to meet your requirements in various scenarios. The traffic monitoring and alerting feature helps you avoid the risk caused by sudden traffic surges.

Elastic Billing

Local peering connections are free of charge. Cross-region peering connections support the Subscription billing mode with tiered pricing.

Limit
Peer VPCs cannot overlap in CIDR blocks. When one VPC is connected to multiple VPCs, the CIDR blocks of the multiple peer VPCs must be unique.
