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 describes how to select regions and zones.

Regions

Concept

Regions are geographical locations where Alibaba Cloud data centers are deployed. Regions are divided based on cities where data centers reside. For example, the data centers of the Australia (Sydney) region reside in Sydney.

How to select regions

Notice 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
Geographical location

A region that is closer to the geographical location of your users provides lower latency and higher access speed.

We recommend that you select a region based on your business requirements on network latency.

Communication between cloud services over an internal network
Notice If you have purchased a cloud network service to connect the cloud services, ignore this item.
  • If you do not need the cloud services to communicate with each other over an internal network, deploy the services in different regions or in the same region.
  • If you need the 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 buy page of your resource.

Zones

Concept

Each region has multiple isolated locations known as zones. Each zone has its own independent power supply and networks. For example, the China (Qingdao) region has two zones, which are Qingdao Zone B and Qingdao Zone C. When instances are deployed within the same zone, the network latency is low and the access speed is high between the instances.

How to select zones

Notice When you create or purchase an Alibaba Cloud resource, you must select a zone to deploy the resource. After the resource is created or purchased, you cannot change the zone of the resource.
Zones within the same region can communicate with each other over an internal network. Fault isolation can be enabled between zones. This way, if faults occur in a zone, other zones are not affected and continue to run as expected. We recommend that you select zones based on your business 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. Only zones in the same region can communicate with each other over an internal network and are connected by using low-latency links. Zones in different regions are completely isolated.

The following figure shows the relationships between regions and zones.

Notice In the figure, Region 1 has three zones and Region 2 has three zones.

Notice This topic lists all regions and zones that are supported by Alibaba Cloud. The regions and zones supported by each cloud service may vary. For more information about the regions and zones supported by a specific cloud service, see the documentation of the cloud service.
