You can now launch M4 instances when using Amazon Relational Database Service (RDS) for MySQL, MariaDB, PostgreSQL, Oracle and SQL Server in the China (Beijing) Region Operated by Sinnet. Amazon RDS is a managed database service that makes it easy to set up, operate, and scale a relational database in the cloud.

M4 Instances have a good balance of compute, memory and network resources and are Amazon EBS-optimized by default. Supported M4 instances range from 2 to 40 vCPUs and 8 GB to 160 GB of memory, and have superior performance and generally lower prices than RDS M3 instances. They feature a custom Intel Xeon E5-2676 v3 Haswell processor optimized specifically for Amazon Web Services. They run at a base clock rate of 2.4 GHz and can go as high as 3.0 GHz with Intel Turbo Boost. To learn more about the benefits of the M4 instance type for Amazon RDS, visit the DB Instance Classes documentation.

Amazon RDS M4 instances are available for databases running MySQL 5.5, 5.6 and 5.7, MariaDB 10.0 and 10.1, PostgreSQL 9.3, 9.4, 9.5, and 9.6, Oracle Database 11g and 12c, and Microsoft SQL Server 2008 R2, 2012, 2014 and 2016. You can create new M4 DB instances with just a few clicks using the "Launch DB Instance" wizard in the Amazon Management Console. To migrate an existing DB instance, first ensure your instance is running a database engine version supported on M4. Then use the “Modify DB Instance” option and select the desired instance class.
