Regions

Overview

A region is the physical location of an IDC. In Tencent Cloud, regions are fully isolated from each other, ensuring cross-region stability and fault tolerance. When purchasing Tencent Cloud services, we recommend selecting the region closest to your end users to minimize access latency and improve download speed.

Characteristics

The networks of different regions are fully isolated from each other, and Tencent Cloud services in different regions cannot communicate using private networks by default.
Tencent Cloud services in different VPCs can communicate with each other through Cloud Connect Network that is faster and steadier.
Note：
Shenzhen/Shanghai Finance Zones are tailor-made AZs for compliance with regulatory requirements in the finance industry and feature high security and isolation. Currently, they are available for CVM, finance database, Redis storage, and face recognition services. They can be activated by verified financial customers by contacting customer service.

AZs

Overview

An availability zone (AZ) is a physical IDC of Tencent Cloud with independent power supply and network in the same region. It can ensure business stability, as failures (except for major disasters or power failures) in one AZ are isolated without affecting other AZs in the same region. By starting an instance in an independent AZ, users can protect their applications from being affected by a single point of failure.

Characteristics

Tencent Cloud services in the same VPC are interconnected via the private network, which means they can communicate using private IPs, even if they are in different AZs of the same region.
Note：
Private network interconnection refers to the interconnection of resources under the same account. Resources under different accounts are completely isolated on the private network.

List of Regions and AZs

Note：
Resources available in different regions and AZs may be sold out and become unavailable, and previously sold-out resources may be replenished. The resource availability will be assessed and adjusted based on the actual business usage as displayed on the purchase page in the console.
The Memcached Edition is currently available in the following regions: Qingyuan, Chengdu, Beijing, Shanghai, Guangzhou, Shenzhen Finance, Shanghai Finance, Singapore, and Hong Kong.
