This topic describes the concept of Alibaba Cloud regions and zones, the relationship between regions and zones, and the regions and zones that are supported by Alibaba Cloud. This topic also provides guidelines on how to select regions and zones for your use cases.
Regions
Concept
Regions are geographical locations where Alibaba Cloud data centers are deployed. Regions are typically named after the cities where the data centers are deployed. For example, data centers that are deployed in Sydney all belong to the Australia (Sydney) region.
Select a region
When you create or purchase an Alibaba Cloud resource, you can select the region in which to deploy the resource. The resource is region-specific, and you cannot change the region of the resource.
When you select a region, take note of the following items.
Item | Description |
Geographic location | Services deployed in a region that is geographically closer to your users are more responsive when your users access your services. We recommend that you select a region based on your requirements on network latency. |
Communication between cloud services over an internal network | Important If you have purchased a cloud networking service to connect your cloud services, ignore this item.
|
Resource price | You can select a region based on your budget. The prices of resources may vary based on regions. For more information, see the product page or resource buy page. |
Zones
Concept
The zone in which you want to deploy your resources. Each region has multiple isolated locations known as zones, which have their own independent power supply and network. For example, the China (Qingdao) region has two zones, which are Qingdao Zone B and Qingdao Zone C. Resources that are deployed within the same zone share the same network, and therefore have minimal latency between each other. This means that services deployed within the same zone have faster communication speeds, which translates into more efficient business operations.
Select a zone
When you create or purchase an Alibaba Cloud resource, you can select the zone in which to deploy the resource. The resource is zone-specific, and you cannot change the zone of the resource.
Zones within the same region are interconnected over an internal network. Each zone is independent of each other, providing effective fault isolation. If you distribute your services across multiple zones and one zone fails, services in other zones can continue to serve requests. We recommend that you appropriately distribute your services across multiple zones based on your requirements on disaster recovery and network latency.
If your application requires high disaster recovery capabilities, we recommend that you deploy instances in different zones within the same region.
If your application requires low latency, we recommend that you deploy instances within the same zone.
Relationship between regions and zones
A region consists of multiple zones. Zones in the same region are interconnected over a low-latency internal network. Zones in each region are completely isolated from zones in other regions.
The following figure shows the relationships between regions and zones.
In the figure, Region 1 has three zones and Region 2 has three zones.

Regions and zones
This section lists all the regions and zones of Alibaba Cloud. For more information, see Global Infrastructure of Alibaba Cloud.
The availability of some cloud services may vary with regions and zones. To find out if the cloud service you want to use is available in a particular zone, see the documentation of the cloud service.
