Areas and availability zones

Updated Time:2023-02-06  Views:17067


Geography refers to the geographical area in which the data centre is located, usually by the region/city in which the data centre is located. For example, the Eastern US geography indicates that the region in which the data centre is located is Texas.

How to choose a territory

Note: You will need to select a deployment region when purchasing resources from this site, and you will not be able to change your region after a successful purchase.

You will need to consider the following factors when choosing a region.


The closer the user is to the location where the resource is deployed, the lower the network latency and the faster the access speed.

It is recommended that you choose your geography based on the latency requirements of your business scenario.

2. Intranet interoperability requirements when using multiple products

If your service does not require intranet interoperability, you can deploy it in a different geography or in the same geography.

If your service requires intranet interoperability, deploy it in the same availability zone.

3. Resource prices

Choose the right region for your budget.

Prices of resources may vary from region to region, please refer to the product details page or product purchase page on this site for pricing information.

Availability zones

Availability zones are physical areas within the same geographical area where power and network are independent of each other. There is less network latency between instances within the same availability zone and their users have faster access.

How to choose an availability zone

Note: You will need to select the availability zone for your deployment when you purchase the resources on this site.

Fault isolation is possible between availability zones, i.e. if one availability zone fails, it will not affect the normal operation of other availability zones. Whether or not you place instances within the same availability zone depends on your application's requirements for disaster recovery and network latency.

If your application requires a high level of disaster tolerance, it is recommended that instances are deployed in different availability zones within the same geographic region.

If your application requires low network latency between instances, it is recommended that you create instances within the same availability zone.

The relationship between geography and availability zones

A territory is usually made up of several availability zones. The availability zones are completely segregated between different territories.
