Amazon Relational Database Service (Amazon RDS) on AWS Outposts now supports additional production ready versions of MySQL (8.0.19, 8.0.20, 8.0.21) and PostgreSQL (12.3, 12.4) for deployment. Amazon RDS on Outposts allows you to deploy fully managed database instances in your on-premises environments. AWS Outposts is a fully managed service that extends AWS infrastructure, AWS services, APIs, and tools to virtually any datacenter, co-location space, or on-premises facility for a truly consistent hybrid experience. You can deploy Amazon RDS on Outposts to set up, operate, and scale MySQL and PostgreSQL relational databases on-premises, just as you would in the cloud.
