Amazon RDS allows you to use the AWS Management Console or a simple set of web services APIs to create, delete and modify relational database instances (DB Instances). You can also control access and security for your instance(s) and manage your database backups and snapshots. For a full list of the available Amazon RDS APIs, please see the Amazon RDS API Guide. Some of the most commonly used APIs and their functionality are listed below:

  • Launch DB Instance — Provision a new DB Instance, specifying the DB Engine (SQL Server edition), license model, DB Instance class, storage capacity, DB Engine version (optional), and the backup retention policy you wish to use. A few clicks on the AWS Management Console is all that’s needed to give you access to a running SQL Server, with the software pre-installed and the available resource capacity you request.
  • Modify DB Instance — Modify settings for a running DB Instance. This functionality lets you scale the resources available to your DB Instance in response to the load on your database, or change how it is automatically backed up and maintained on your behalf. You can also use this functionality to gain optional control over how DB Engine versions are upgraded.
  • Take DB Snapshot — Generate a snapshot of your DB Instance. You can restore your DB Instance to user-created snapshots at any point, even to reinstate a previously deleted DB Instance.
  • Restore To Point In Time — Create a new DB Instance from a point-in-time backup. You can restore to any point within the retention period you specified, usually up to the last five minutes of your database’s usage.
  • Delete DB Instance — With Amazon RDS, you can terminate your DB Instance at any time and pay only for the resources you used.

Amazon RDS supports multiple SQL Server (2008 R2, 2012, 2014 and 2016) Editions. Support for a given edition varies by licensing model. See pricing for more information on the licensing models offered by Amazon RDS for SQL Server:

You will be charged at the end of each month for the Amazon RDS resources you actually consume. Once a DB Instance you have created is available for connection, you will be charged for each hour your DB Instance is running. Each DB Instance will run until termination, which occurs when you issue an API call to delete the DB Instance, or in the event of an instance failure. Partial DB Instance hours consumed are billed as full hours. In addition to DB Instance hours, you are also billed for your monthly storage, IO requests, and backups. If you scale your storage capacity within the billing period, your bill will be pro-rated accordingly.
