Regions and zones

Last Updated: Jul 07, 2018

Regions

Alibaba Cloud regions are physical locations (data centers) that spread all over the world to reduce the network latency. Zones are the physical areas with independent power grids and networks in one region. The network latency within the same zone is shorter.

The available regions vary with products. The following table lists all the Alibaba Cloud regions, corresponding cities, and Region IDs.

Note: To know the list of available regions of each product, see the Alibaba Cloud Global Infrastructure.

Regions in Mainland China

Zones

Zones are the physical areas with independent power grids and networks in one region. The network latency for instances within the same zone is shorter.

Intranet communication can take place between instances in different zones of the same region, and fault isolation can be performed between zones. Whether or not instances can be deployed in the same zone depends on the requirements for disaster recovery capabilities and network latency.

  • If your applications require high disaster recovery capabilities, we recommend that you deploy your instances in different zones of the same region.
  • If your applications require low network latency between instances, we recommend that you create your instances in the same zone.

For more information about regions and zones, see the Alibaba Cloud Global Infrastructure.

How to select a region

Regions in mainland China

Regions in mainland China include China East 1, China East 2, China North 1, China North 2, China North 3, China North 5, and China South 1.

The regions offer BGP backbone network lines covering all provinces and municipalities in mainland China and providing fast yet stable access within mainland China.

The regions are similar to each other in terms of infrastructure, BGP network quality, service quality, ECS operation, and configuration. In general cases, we recommend that you select a data center closest to your end users to have them gain quick access.

International regions

Alibaba Cloud’s international regions are data centers outside mainland China. They offer access at international bandwidth, targeting areas outside mainland China. Access to these regions from mainland China may experience high latency. Therefore, they are not recommended for access from mainland China.

  • Asia Pacific

    • Hong Kong
      The data center in Hong Kong offers access at international bandwidth, covering Hong Kong and Southeast Asia. If you have business operation in Hong Kong and Southeast Asia, you can select this region.

    • Asia Pacific SE 1
      The data center in Asia Pacific SE 1 is located in Singapore. If you have business operation in Hong Kong and Southeast Asia, you can select this region.

    • Asia Pacific SE 2
      The data center in Asia Pacific SE 2 is located in Sydney, Australia. If you have business operation in Australia, select the Asia Pacific SE 2 region.

    • Asia Pacific SE 3 and Asia Pacific SE 5
      The data center in Asia Pacific SE 3 is located in Kuala Lumpur, Malaysia. The data center in Asia Pacific SE5 is located in Jakarta, Indonesia. They provide high speed and low latency services for users in Southeast Asia countries, including Malaysia, Singapore, Indonesia, Thailand, and their neighboring countries.

    • Asia Pacific NE 1
      The data center in Asia Pacific NE 1 is located in Tokyo, Japan. If you have business operations in Japan, Northeast Asia, and South Korea, select the Asia Pacific NE 1 region.

  • North America and South America

    • US West 1
      The data center in US West 1 is located in Silicon Valley. It is directly connected to the backbone networks of multiple American operators through BGP lines. In addition to the United States, this data center extends its reach to South America and Continental Europe. If you have business operation in America and Continental Europe, select this region.

    • US East 1
      The data center in US East 1 is located in Virginia of the United States. If you have business operation in America and Continental Europe, select this region.

  • Germany 1
    The data center in Germany 1 is located in Frankfurt. If you have business operation in Continental Europe, select the Germany 1 region.

  • Middle East 1
    The data center in Middle East 1 is located in Dubai, United Arab Emirates. If you have business operations in the Middle East, select the Middle East 1 region.

Intranet communication between Alibaba Cloud products across regions

Intranet communication between Alibaba Cloud products that are not in the same region is not supported, which means:

  • ECS instances in different regions cannot communicate with each other on the intranet.

  • ECS instances and other products in different regions, such as ApsaraDB for RDS and OSS instances, cannot communicate with each other on the intranet.

  • Server Load Balancer cannot be deployed for ECS instances in various regions.

About business license record filing

If you must file your business license for record, pay attention to the following points:

  • If your company is located in Beijing, select the China North 2 region for the ECS instance you have purchased.

  • If your company is located in Guangdong, select the China South 1 region for the ECS instance you have purchased.

Note: In mainland China, the approval requirements for business record filing vary according to Provincial communication management bureaus.
