Region and AZ

What Are Regions and AZs?

A region and availability zone (AZ) identify the location of a data center. You can create resources in regions and AZs.

shows the relationship between regions and AZs.

What Are the Considerations for Selecting a Region?

When selecting a region, consider the following factors:

• Location

  Select a region close to you or your target users to minimize network latency and increase access speed. However, there is no distinct difference between the infrastructure, BGP network quality, and resource operations and configurations in Chinese mainland regions. Therefore, you do not need to consider the network latency when selecting a region in Chinese mainland.

  • If you or your target users are in the Asia Pacific area excluding the Chinese mainland, select the CN-Hong Kong, AP-Bangkok, or AP-Singapore region.
  • If you or your target users are in Africa, select the AF-Johannesburg region.
  • If you or your target users are in Europe, select the EU-Paris region.
• Resource price

  Resource prices may vary in different regions. For details, see .

What Are the Considerations for Selecting an AZ?

Consider the requirements for disaster recovery (DR) and network latency when selecting an AZ:

• Deploy resources in different AZs in the same region for DR purposes.
• Deploy resources in the same AZ for minimum latency.

How Do I Obtain an Endpoint?

When you use resources by using an API, you must specify its regional endpoint. For details about Huawei Cloud regions and endpoints, see .
