Amazon Relational Database Service (Amazon RDS) on Outposts is available in Preview, allowing you to deploy fully managed Amazon RDS database instances in your on-premises environments. AWS Outposts bring native AWS services, infrastructure, and operating models to virtually any data center, co-location space, or on-premises facility. You can deploy Amazon RDS on Outposts to set up, operate, and scale relational databases on premises, just as you would in the cloud. Amazon RDS provides cost-efficient and resizable capacity for databases in Outposts, while automating time-consuming administration tasks including infrastructure provisioning, database setup, patching, and backups, freeing you to focus on your applications.
