Services or capabilities described in Amazon Web Services documentation might vary by Region. To see the differences applicable to the China Regions, see Getting Started with Amazon Web Services in China (PDF).

Aurora Serverless v1 and Aurora database engine versions

Aurora Serverless v1 is available in certain Amazon Web Services Regions and for specific Aurora MySQL and Aurora PostgreSQL versions only. For the current list of Amazon Web Services Regions that support Aurora Serverless v1 and the specific Aurora MySQL and Aurora PostgreSQL versions available in each Region, see Aurora Serverless v1.

Aurora Serverless v1 uses its associated Aurora database engine to identify specific supported releases for each database engine supported, as follows:

When minor releases of the database engines become available for Aurora Serverless v1, they are applied automatically in the various Amazon Web Services Regions where Aurora Serverless v1 is available. In other words, you don't need to upgrade your Aurora Serverless v1 DB cluster to get a new minor release for your cluster's DB engine when it's available for Aurora Serverless v1.

Aurora MySQL Serverless

If you want to use Aurora MySQL-Compatible Edition for your Aurora Serverless v1 DB cluster, you can choose between Aurora MySQL 5.6-compatible and Aurora MySQL 5.7-compatible versions. These two editions of Aurora MySQL differ significantly. We recommend that you compare their differences before creating your Aurora Serverless DB cluster so that you make the right choice for your use case. To learn about enhancements and bug fixes for Aurora MySQL Serverless 5.6 and 5.7, see Database engine updates for Aurora Serverless clusters in the Release Notes for Aurora MySQL.

Aurora PostgreSQL Serverless

If you want to use Aurora PostgreSQL for your Aurora Serverless v1 DB cluster, you can choose among Aurora PostgreSQL 10-compatible and 11-compatible versions. Minor releases for Aurora PostgreSQL-Compatible Edition include only changes that are backward-compatible. Your Aurora Serverless v1 DB cluster is transparently upgraded when an Aurora PostgreSQL minor release becomes available for Aurora Serverless v1 in your Amazon Web Services Region.

For example, the minor version Aurora PostgreSQL 10.18 release was transparently applied to all Aurora Serverless v1 DB clusters running the previous Aurora PostgreSQL version. For more information about the Aurora PostgreSQL version 10.18 update, see PostgreSQL 10.18 in the Release Notes for Aurora PostgreSQL.
