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 AWS services in China.

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.

Region Availability

Amazon Relational Database Service is available in the following regions in China:

  • Beijing Region

  • Ningxia Region

Feature Availability and Implementation Differences

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

  • 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.

  • For current information on DB Instance classes, see Amazon RDS Pricing.

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