This topic provides a complete list of regions and zones of Alibaba Cloud.

Region

A region is a geographic area where data centers are deployed. The region of an Alibaba Cloud resource cannot be changed after the resource is created. The following table describes the information about all regions of Alibaba Cloud, including the region IDs and the cities where the regions reside.
Note Available regions vary with services.
  • Regions in mainland China

When you select a region, you must consider the following factors:
  • Geographical locations
    Select a region based on the geographical location of you and your users.
    • Regions in mainland China

      In mainland China, we recommend that you select the region that is closest to the geographical location of your users for faster access. However, in different regions in mainland China, Alibaba Cloud services are almost the same in terms of network infrastructures, Border Gateway Protocol (BGP) network quality, quality of service (QoS), and ease of use and configurations on Elastic Compute Service (ECS) instances. BGP networks ensure fast access to all regions in mainland China.

    • Regions outside mainland China

      Bandwidths provided in regions outside mainland China are applicable to users in those regions. If you are located in mainland China, we recommend that you do not select regions outside mainland China because you may experience high latency when using those regions.

  • Connection between Alibaba Cloud services
    If you use multiple Alibaba Cloud services together, take note of the following items:
    • ECS instances, ApsaraDB RDS instances, and Object Service Storage (OSS) buckets that are created in different regions cannot communicate with each other over internal networks.
    • Server Load Balancer (SLB) cannot distribute network traffic across ECS instances in different regions. ECS instances that you purchased in different regions cannot be associated with the same SLB instance.
  • Resource price

    The price of resources may vary by region. For more information, see the Pricing page.

  • ICP license

    When you select a region, you need to consider the special requirements of the local authorities. For example, if you purchase an ECS instance deployed in a region in mainland China and use the instance as a web server, you must apply for an ICP license.

    When you apply for an ICP license, take note of the following items:
    • If you want to apply for an ICP license for services in Beijing, select the China (Beijing) region.
    • If you want to apply for an ICP license for services in Guangdong, select the China (Shenzhen) region.
    Note The approval requirements for ICP licenses vary from province to province. For the latest requirements, visit the ICP license application website of the local Communications Administration.

Zone

A zone is a physical area within a region that has its own independent power grids and networks. The latency of connections between instances within the same zone is lower.

Zones within the same region can access each other over the internal network. When a zone is down, other zones are not affected. We recommend that you choose a deployment method that meets your disaster recovery and latency requirements.
  • If your application requires high disaster recovery capabilities, we recommend that you create instances in different zones of the same region.
  • If your application requires low latency, we recommend that you create instances within the same zone.
