Easy, managed deployments
Amazon RDS for SQL Server is a managed service that is designed for developers who require the features and capabilities of SQL Server for building a new application. You can also move existing applications that utilize SQL Server to Amazon RDS without having to rewrite the application completely. Since Amazon RDS for SQL Server provides you direct access to the native capabilities of the SQL Server edition you have specified, your applications and tools should work seamlessly.
- Pre-configured Parameters – Amazon RDS for SQL Server deployments are pre-configured with a set of parameters and settings appropriate for the SQL Server edition and DB Instance class you have selected. You can simply launch a SQL Server DB Instance and connect it to your application within minutes without additional configuration. If you desire additional control, you can achieve it via DB Parameter Groups.
- Monitoring and Metrics – Amazon RDS provides Amazon CloudWatch metrics for your DB Instance deployments at no additional charge. You can use the AWS Management Console to view key operational metrics for your DB Instance deployments, including compute/memory/storage capacity utilization, I/O activity, and DB Instance connections.
- DB Event Notifications – Amazon RDS provides Amazon SNS notifications via email or SMS for your DB Instance deployments. You can use the AWS Management Console or the Amazon RDS APIs to subscribe to over 40 different DB events associated with your Amazon RDS deployments.
- Automatic Software Patching – Amazon RDS enables you to have the SQL Server software powering your deployment stay up-to-date with the latest patches automatically. You can exert optional control over when and if your DB Instance is patched via DB Engine Version Management.
Fast, predictable storage performance
- General Purpose (SSD) – Amazon RDS General Purpose (SSD) storage delivers a consistent baseline of 3 IOPS per provisioned GB and provides the ability to burst up to 3,000 IOPS.
- Provisioned IOPS (SSD) – Using the Amazon RDS APIs or with a few clicks on the AWS Management Console, you can provision the IOPS for your SQL Server DB Instance. Starting immediately, when you create new DB Instances using the AWS Management Console or the Amazon RDS APIs, you can provision from 1,000 IOPS to 32,000 IOPS with corresponding storage from 100GB to 16TB for new SQL Server DB Instances. If you want to migrate an existing SQL Server DB Instance to Provisioned IOPS storage, you can export the data from your DB Instance and import into a new DB Instance equipped with Provisioned IOPS storage.
Backup and disaster recovery
- Automated Backups – Turned on by default, the automated backup feature of Amazon RDS enables point-in-time recovery for your DB Instance. Amazon RDS will back up your DB Instance daily and your transaction logs at 5 minute intervals and store both for a user-specified retention period. This allows you to restore your DB Instance to any second during your retention period, up to the last five minutes. Your automatic backup retention period can be configured to up to 35 days.
- DB Snapshots – DB Snapshots are user-initiated backups of your DB Instance. These full database backups will be stored by Amazon RDS until you explicitly delete them. You can create a new DB Instance from a DB Snapshot whenever you desire.
- DB Instance Class – Using a few clicks of the AWS Management Console, you can scale the compute and memory resources powering your deployment up or down. Scaling operations typically complete within a few minutes.
- Storage and IOPS – As your storage requirements grow you can provision additional storage on-the-fly with zero downtime.
Availability and reliability
- Automatic Host Replacement – Amazon RDS will automatically replace the compute instance powering your deployment in the event of a hardware failure.
- Multi-AZ Deployments – When you create or modify your DB Instance to run as aMulti-AZ deployment, Amazon RDS will automatically provision a primary database in one Availability Zone and maintain a synchronous "standby" replica in a different Availability Zone. In the event of planned database maintenance or unplanned service disruption, Amazon RDS will automatically failover the SQL Server database to the up-to-date standby. Database operations can resume quickly without any manual intervention.
Isolation and Security
Using Amazon VPC, you can isolate your DB Instances in your own virtual network, and connect to your existing IT infrastructure using industry-standard encrypted IPSec VPN. To learn more about Amazon RDS in VPC, refer to the Amazon RDS User Guide. In addition, using Amazon RDS, you can configure firewall settings and control network access to your DB Instances.
SQL Server Editions
Amazon RDS supports multiple editions of SQL Server (2012, 2014, 2016, 2017, and 2019) including Express, Web, Standard Edition and Enterprise Edition.
Not all editions may be available in all regions; see pricing for details.
Please note that in accordance with Microsoft’s licensing policies, SQL Server Web Edition can only be used to support public and internet accessible Web pages, Websites, Web applications and Web services. Refer to the AWS Service Terms for more details.

Paying for What You Use
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.
For details, see the Amazon RDS for SQL Server pricing page.
