The Beginner's Guide:Regions and Zones

Last Updated:May 21, 2024

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, the data centers of the Malaysia (Kuala Lumpur) region reside in Kuala Lumpur.

Select a region

Important

When you create or purchase an Alibaba Cloud resource, you must select a region to deploy the resource. After the resource is created or purchased, 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.

  • If you do not need your cloud services to communicate with each other over an internal network, the services do not need to be deployed in the same region.

  • If you need your cloud services to communicate with each other over an internal network, deploy the services in the same region.

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 (Beijing) region has twelve zones, which include Beijing Zone A and Beijing Zone B and so on. 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

Important

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 after deployment.

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.

Important

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.

Important

This topic lists all regions and zones that are supported by 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.

The following table lists all regions and zones of Alibaba Cloud.
