Region and AZ
Concept
A region and availability zone (AZ) identify the location of a data center. You can create resources in a specific region and AZ.
- Regions are divided from the dimensions of geographical location and network latency. Public services, such as Elastic Cloud Server (ECS), Elastic Volume Service (EVS), Object Storage Service (OBS), Virtual Private Cloud (VPC), Elastic IP (EIP), and Image Management Service (IMS), are shared within the same region. Regions are classified as universal regions and dedicated regions. A universal region provides universal cloud services for common tenants. A dedicated region provides services of the same type only or for specific tenants.
- An AZ contains one or multiple physical data centers. Each AZ has independent cooling, fire extinguishing, moisture-proof, and electricity facilities. Within an AZ, computing, network, storage, and other resources are logically divided into multiple clusters. AZs within a region are interconnected using high-speed optical fibers to allow you to build cross-AZ high-availability systems.
Figure 1 shows the relationship between the regions and AZs.
HUAWEI CLOUD provides services in many regions around the world. Select a region and AZ based on requirements. For more information, see HUAWEI CLOUD Global Products and Services.
How to Select a Region?
When selecting a region, consider the following factors:
- Location
You are advised to select a region close to you or your target users. This reduces network latency and improves access rate. However, Chinese mainland regions provide basically the same infrastructure, BGP network quality, as well as operations and configurations on resources. Therefore, if you or your target users are in the Chinese mainland, you do not need to consider the network latency differences when selecting a region.
The countries and regions outside the Chinese mainland, such as Bangkok and Hong Kong SAR, China, provide services for users outside the Chinese mainland. If you or your target users are in the Chinese mainland, these regions are not recommended due to high access latency.
- If you or your target users are in Asia Pacific excepting the Chinese mainland, select the CN-Hong Kong or AP-Bangkok region.
- If you or your target users are in Africa, select the AF-Johannesburg region.
- Resource price
Resource prices may vary in different regions. For details, see Product Pricing Details.
When selecting a region for DES, you need to consider the impact of geographical location factors on the transportation of data transmission media. You are advised to select a region close to you or your target users. This reduces the transportation time.
How to Select an AZ?
When determining whether to deploy resources in the same AZ, consider your applications' requirements on disaster recovery (DR) and network latency.
- For high DR capability, deploy resources in different AZs in the same region.
- For low network latency, deploy resources in the same AZ.
Regions and Endpoints
Before using an API to call resources, specify its region and endpoint. For more details, see Regions and Endpoints.
