Getting Started with Amazon AWS
AWS services or capabilities described in AWS documentation might vary by Region. To see the differences applicable to the China Regions, see Getting Started with Amazon AWS.

Amazon Relational Database Service

Amazon Relational Database Service (Amazon RDS) is a web service that makes it easy to set up, operate, and scale a relational database in the cloud. It provides cost-efficient and resizable capacity while managing time-consuming database administration tasks, freeing you up to focus on your applications and business.

Please note the following Amazon AWS implementation particulars, which are potentially relevant to all services in the Beijing and Ningxia Regions.

  • To use services in the Beijing and Ningxia Regions, you need an account and credentials specific to the Beijing and Ningxia Regions. Accounts and credentials for other AWS Regions will not work for services operating in the Beijing and Ningxia Regions. Likewise, accounts and credentials for the Beijing and Ningxia Regions will not work for other AWS Regions.

  • There are two Availability Zones in the Beijing Region.

  • There are three Availability Zones in the Ningxia Region.

  • In AWS Identity and Access Management (IAM), you can grant or deny a service access to resources using the Principal policy element. Service principal values vary by Region.

  • The domain for both the Beijing and Ningxia Regions is amazonaws.cn.

  • The endpoints for services in the China (Beijing) Region and the China (Ningxia) Region are different from other global endpoints.

    • The endpoint domain for both the Beijing and Ningxia Regions is amazonaws.com.cn.

    • For an endpoint in the China (Beijing) Region, the Region value should be cn-north-1.

    • For an endpoint in the China (Ningxia) Region, the Region value should be cn-northwest-1.

    • For example, the endpoint for Elastic Load Balancing in the Beijing Region is elasticloadbalancing.cn-north-1.amazonaws.com.cn.

    Endpoint syntax varies from service to service. For more information, see China (Beijing), China (Ningxia), and the service-specific documentation.

  • In the China Regions, the Amazon Resource Name (ARN) syntax includes a cn.

    For example: arn:aws-cn:iam::123456789012:user/division_abc/subdivision_xyz/Bob.

  • The EC2-Classic platform is not supported.

  • AWS Marketplace is not supported.

  • The free usage tier is not available in the China Regions.

Note

The AWS documentation might show code examples for endpoints and ARNs that are not specific for the Beijing and Ningxia Regions. When using examples, verify you are using the correct endpoints and ARNs for your Region.

Language Options

Feature Availability and Implementation Differences

The Amazon AWS implementation of Amazon RDS is unique in the following ways:

  • Multi-AZ deployments are not supported for DB instances running Microsoft SQL Server.

  • Cross-region features, such as DB snapshot copying across regions and read replication across multiple regions, are currently not supported between the Beijing Region and other non-China Regions.

  • Backup and maintenance windows:

    • If you don't specify a preferred backup window when you create the DB instance, Amazon RDS assigns a default 30-minute backup window which is selected at random from between 06:00 and 14:00 UTC.

    • If you don't specify a preferred maintenance window when you create the DB instance, Amazon RDS assigns a default 30-minute maintenance window on a randomly selected day of the week from between 06:00 and 14:00 UTC.

  • The following DB instance classes are available:

    • t1.micro: 613 MB memory, up to 1 ECU, 64-bit platform, low I/O capacity.

    • m1.small: 1.7 GB memory, 1 ECU (1 virtual core with 1 ECU), 64-bit platform, moderate I/O capacity.

    • m3.medium: 3.75 GB memory, 3 ECUs, 64-bit platform, moderate I/O capacity.

    • m3.large: 7 GB memory, 6.5 ECUs, 64-bit platform, high I/O capacity.

    • m3.xlarge: 15 GB memory, 13 ECUs, 64-bit platform, high I/O capacity.

    • m3.2xlarge: 30 GB memory, 26 ECUs, 64-bit platform, high I/O capacity.

  • You can have up to 20 manual snapshots for your account in the Beijing and Ningxia Regions.

  • To use the Bring Your Own License model with a DB instance running Microsoft SQL Server, you must provide your Microsoft License Mobility Agreement information. Fill out the form once for each of your AWS accounts. In the Beijing and Ningxia Regions, you provide your License Mobility Agreement information by using the AWS website form form to specify the number of licenses that you have.

User Guides

Amazon AWS user guides are available in HTML and PDF, in both Chinese and English. API guides are available in HTML and PDF, in English only. Currently, the API guides are not available in the Beijing and Ningxia Regions. Links to API guides will take you to the global AWS site. Note that some features and functionality described in the guides may not be available in the current Amazon AWS release.
