ARNs and Endpoints in AWS China

AWS China comprises 2 AWS regions, Beijing and Ningxia, with 6 availability zones in total. Beijing is operated by Sinnet and Ningxia is operated by NWCD. As you probably know from my previous blog posts, AWS China has completely separated regions from global regions. Due to the separate infrastructures, the user accounts of AWS China are completely different from AWS Global. In the same way, the AWS endpoints and ARNs in AWS Global and AWS China are slightly different.

What is an AWS Endpoint?

You use an endpoint to connect programmatically to an AWS service globally as well as in China. An endpoint is the URL of the entry point for an AWS service.

The endpoints for services in the Beijing and Ningxia regions differ from other AWS global endpoints. The endpoint domain for both the Beijing and Ningxia regions is „amazonaws.com.cn“.

What is an AWS Code?

Every region in AWS has an endpoint code, that you can use to make your requests and deploy your resources in a specific region.

Region Code
Beijing cn-north-1
Ningxia cn-northwest-1

You have to keep in mind, this only applies to the region-specific services (which are essentially most of the AWS services). However, there are some services, such as IAM, Route53, WAF, and CloudFront, among others, that are global and therefore do not support regions.

  • The endpoints for these services do not include a region: „service.amazonaws.com.cn“
  • For example, route53.amazonaws.com.cn is the endpoint for the Route53 service in China.

  • The services that support regions include the region in the endpoint: „service.region.amazonaws.com.cn“
  • For example, „dynamodb.cn-north-1.amazonaws.com.cn“ is the endpoint for the Amazon DynamoDB service in the Beijing Region, and „dynamodb.cn-northwest-1.amazonaws.com.cn“ is the endpoint for Amazon DynamoDB in the Ningxia Region.

    For a complete list of endpoints in China Regions, see the following topics:

  • Beijing Region Endpoints
  • Ningxia Region Endpoints
  • Now that we know what the AWS endpoints are and how they work specifically in the China regions, it’s time to talk about the ARNs.

    What are the Amazon Resource Names (ARNs)?

    Amazon Resource Names (ARNs) uniquely identify AWS resources. You use an ARN to specify a resource across all of AWS, such as in AWS Identity and Access Management (IAM) policies, Amazon Relational Database Service (Amazon RDS) tags, and API calls.

    The ARNs are defined as: arn:partition:service:region:account-id:resource-id

    In AWS China regions, the ARN syntax includes cn and this is the main difference with AWS global ARNs.

    Region ARN partition
    China aws-cn
    Global aws

    Here are some examples:

  • arn:aws-cn:s3:cn-northwest-1:1234567890:my_bucket
  • arn:aws-cn:iam::1234567890:user/David
  • arn:aws-cn:ec2:cn-north-1:1234567890:*
  • arn:aws-cn:rds:cn-north-1:1234567890:db:mysql-db
  • arn:aws-cn:ec2:cn-northwest-1:1234567890:volume/vol-1a2b3c4d
