Amazon Web Services has made instances powered by its home-baked Arm servers more approachable by starting a preview of its Relational Database Service (RDS) on the hardware.
RDS is a managed database offering with administration and automation features including hardware provisioning, database setup, patching, and backups. AWS pitches the service as something that helps IT shops focus on applications rather than infrastructure.
The preview supports the installation of MySQL and PostgreSQL on AWS’ Arm-powered M6g and R6g instance types. Amazon has promised support for MariaDB and its own Aurora database soon.
MySQL, PostgreSQL, and MariaDB all run on Arm already. Aurora appears to be new to Arm.

As Amazon never tires of pointing out, the Graviton2 CPUs in its Arm servers can be significantly cheaper to operate than the Xeon-powered kit in its fleet.
Turning on RDS makes it easier to put that claim to the test, because databases are such a ubiquitous workload that building an on-ramp to their use on Arm will almost certainly turn some curiosity into experimentation. It also shows that AWS is going to ensure its many sysadmin-helpers apply equally to x86 and Arm. And once the Amazon cloud delivers the same administrative and developer experience regardless of CPU architecture, if that price/performance promise on Arm holds true users will have an interesting choice before them. ®
