With Amazon RDS, you can create DB instances and DB snapshots, point-in-time restores, and automated or manual backups. DB instances running SQL Server can be used inside a VPC. You can also use Secure Sockets Layer (SSL) to connect to a DB instance running SQL Server, and you can use transparent data encryption (TDE) to encrypt data at rest. Amazon RDS currently supports Multi-AZ deployments for SQL Server using SQL Server Database Mirroring (DBM) or Always On Availability Groups (AGs) as a high-availability, failover solution.
To deliver a managed service experience, Amazon RDS does not provide shell access to DB instances, and it restricts access to certain system procedures and tables that require advanced privileges. Amazon RDS supports access to databases on a DB instance using any standard SQL client application such as Microsoft SQL Server Management Studio. Amazon RDS does not allow direct host access to a DB instance via Telnet, Secure Shell (SSH), or Windows Remote Desktop Connection. When you create a DB instance, the master user is assigned to the db_owner role for all user databases on that instance, and has all database-level permissions except for those that are used for backups. Amazon RDS manages backups for you.
Before creating your first DB instance, you should complete the steps in the setting up section of this guide. For more information, see Setting up for Amazon RDS.

Common management tasks for Microsoft SQL Server on Amazon RDS
The following are the common management tasks you perform with an Amazon RDS for SQL Server DB instance, with links to relevant documentation for each task.
Task area | Relevant documentation |
---|---|
Instance classes, storage, and PIOPS If you are creating a DB instance for production purposes, you should understand how instance classes, storage types, and Provisioned IOPS work in Amazon RDS. |
|
Multi-AZ deployments A production DB instance should use Multi-AZ deployments. Multi-AZ deployments provide increased availability, data durability, and fault tolerance for DB instances. Multi-AZ deployments for SQL Server are implemented using SQL Server's native DBM or AGs technology. |
Configuring and managing a Multi-AZ deployment Multi-AZ deployments using Microsoft SQL Server Database Mirroring or Always On availability groups |
Amazon Virtual Private Cloud (VPC) If your AWS account has a default VPC, then your DB instance is automatically created inside the default VPC. If your account does not have a default VPC, and you want the DB instance in a VPC, you must create the VPC and subnet groups before you create the DB instance. |
|
Security groups By default, DB instances are created with a firewall that prevents access to them. You therefore must create a security group with the correct IP addresses and network configuration to access the DB instance. |
|
Parameter groups If your DB instance is going to require specific database parameters, you should create a parameter group before you create the DB instance. |
|
Option groups If your DB instance is going to require specific database options, you should create an option group before you create the DB instance. |
|
Connecting to your DB instance After creating a security group and associating it to a DB instance, you can connect to the DB instance using any standard SQL client application such as Microsoft SQL Server Management Studio. |
Connecting to a DB instance running the Microsoft SQL Server database engine |
Backup and restore When you create your DB instance, you can configure it to take automated backups. You can also back up and restore your databases manually by using full backup files (.bak files). |
Importing and exporting SQL Server databases using native backup and restore |
Monitoring You can monitor your SQL Server DB instance by using CloudWatch Amazon RDS metrics, events, and enhanced monitoring. |
|
Log files You can access the log files for your SQL Server DB instance. |
There are also advanced administrative tasks for working with SQL Server DB instances. For more information, see the following documentation:
Limitations for Microsoft SQL Server DB instances
The Amazon RDS implementation of Microsoft SQL Server on a DB instance has some limitations that you should be aware of:
-
The maximum number of databases supported on a DB instance depends on the instance class type and the availability mode—Single-AZ, Multi-AZ Database Mirroring (DBM), or Multi-AZ Availability Groups (AGs). The Microsoft SQL Server system databases don't count toward this limit.
The following table shows the maximum number of supported databases for each instance class type and availability mode. Use this table to help you decide if you can move from one instance class type to another, or from one availability mode to another. If your source DB instance has more databases than the target instance class type or availability mode can support, modifying the DB instance fails. You can see the status of your request in the Events pane.
Instance class type Single-AZ Multi-AZ with DBM Multi-AZ with Always On AGs db.*.micro to db.*.medium 30 N/A N/A db.*.large 30 30 30 db.*.xlarge to db.*.16xlarge 100 50 75 db.*.24xlarge 100 50 100 * Represents the different instance class types.
For example, let's say that your DB instance runs on a db.*.16xlarge with Single-AZ and that it has 76 databases. You modify the DB instance to upgrade to using Multi-AZ Always On AGs. This upgrade fails, because your DB instance contains more databases than your target configuration can support. If you upgrade your instance class type to db.*.24xlarge instead, the modification succeeds.
If the upgrade fails, you see events and messages similar to the following:
-
Unable to modify database instance class. The instance has 76 databases, but after conversion it would only support 75.
-
Unable to convert the DB instance to Multi-AZ: The instance has 76 databases, but after conversion it would only support 75.
If the point-in-time restore or snapshot restore fails, you see events and messages similar to the following:
-
Database instance put into incompatible-restore. The instance has 76 databases, but after conversion it would only support 75.
-
-
Some ports are reserved for Amazon RDS, and you can't use them when you create a DB instance.
-
Client connections from IP addresses within the range 169.254.0.0/16 are not permitted. This is the Automatic Private IP Addressing Range (APIPA), which is used for local-link addressing.
-
SQL Server Standard Edition uses only a subset of the available processors if the DB instance has more processors than the software limits (24 cores, 4 sockets, and 128GB RAM). Examples of this are the db.m5.24xlarge and db.r5.24xlarge instance classes.
For more information, see the table of scale limits under Editions and supported features of SQL Server 2019 (15.x)
in the Microsoft documentation. -
Amazon RDS for SQL Server doesn't support importing data into the msdb database.
-
You can't rename databases on a DB instance in a SQL Server Multi-AZ deployment.
-
Make sure that you use these guidelines when setting the following DB parameters on RDS for SQL Server:
-
max server memory (mb)
>= 256 MB -
max worker threads
>= (number of logical CPUs * 7)
For more information on setting DB parameters, see Working with parameter groups.
-
-
The maximum storage size for SQL Server DB instances is the following:
-
General Purpose (SSD) storage – 16 TiB for all editions
-
Provisioned IOPS storage – 16 TiB for all editions
-
Magnetic storage – 1 TiB for all editions
If you have a scenario that requires a larger amount of storage, you can use sharding across multiple DB instances to get around the limit. This approach requires data-dependent routing logic in applications that connect to the sharded system. You can use an existing sharding framework, or you can write custom code to enable sharding. If you use an existing framework, the framework can't install any components on the same server as the DB instance.
-
-
The minimum storage size for SQL Server DB instances is the following:
-
General Purpose (SSD) storage – 20 GiB for Enterprise, Standard, Web, and Express Editions
-
Provisioned IOPS storage – 20 GiB for Enterprise, Standard, Web, and Express Editions
-
Magnetic storage – 20 GiB for Enterprise, Standard, Web, and Express Editions
-
-
Amazon RDS doesn't support running these services on the same server as your RDS DB instance:
Data Quality Services
Master Data Services
To use these features, we recommend that you install SQL Server on an Amazon EC2 instance, or use an on-premises SQL Server instance. In these cases, the EC2 or SQL Server instance acts as the Master Data Services server for your SQL Server DB instance on Amazon RDS. You can install SQL Server on an Amazon EC2 instance with Amazon EBS storage, pursuant to Microsoft licensing policies.
-
Because of limitations in Microsoft SQL Server, restoring to a point in time before successfully running
DROP DATABASE
might not reflect the state of that database at that point in time. For example, the dropped database is typically restored to its state up to 5 minutes before theDROP DATABASE
command was issued. This type of restore means that you can't restore the transactions made during those few minutes on your dropped database. To work around this, you can reissue theDROP DATABASE
command after the restore operation is completed. Dropping a database removes the transaction logs for that database. -
For SQL Server, you create your databases after you create your DB instance. Database names follow the usual SQL Server naming rules with the following differences:
-
Database names can't start with
rdsadmin
. -
They can't start or end with a space or a tab.
-
They can't contain any of the characters that create a new line.
-
They can't contain a single quote (
'
).
-
DB instance class support for Microsoft SQL Server
The computation and memory capacity of a DB instance is determined by its DB instance class. The DB instance class you need depends on your processing power and memory requirements. For more information, see DB instance classes.
The following list of DB instance classes supported for Microsoft SQL Server is provided here for your convenience. For the most
current list, see the RDS console: https://console.aws.amazon.com/rds/
Not all DB instance classes are available on all supported SQL Server minor versions. For example, some newer DB instance
classes such as db.r6i aren't available on older minor versions. You can use the describe-orderable-db-instance-options
SQL Server edition | 2019 support range | 2017 and 2016 support range | 2014 support range |
---|---|---|---|
Enterprise Edition |
|
|
|
Standard Edition |
|
|
|
Web Edition |
|
|
|
Express Edition |
|
|
|
Microsoft SQL Server security
The Microsoft SQL Server database engine uses role-based security. The master user name that you specify when you create a DB
instance is a SQL Server Authentication login that is a member of the processadmin
, public
, and
setupadmin
fixed server roles.
Any user who creates a database is assigned to the db_owner role for that database and has all database-level permissions except for those that are used for backups. Amazon RDS manages backups for you.
The following server-level roles aren't available in Amazon RDS for SQL Server:
-
bulkadmin
-
dbcreator
-
diskadmin
-
securityadmin
-
serveradmin
-
sysadmin
The following server-level permissions aren't available on RDS for SQL Server DB instances:
-
ALTER ANY DATABASE
-
ALTER ANY EVENT NOTIFICATION
-
ALTER RESOURCES
-
ALTER SETTINGS (you can use the DB parameter group API operations to modify parameters; for more information, see Working with parameter groups)
-
AUTHENTICATE SERVER
-
CONTROL_SERVER
-
CREATE DDL EVENT NOTIFICATION
-
CREATE ENDPOINT
-
CREATE SERVER ROLE
-
CREATE TRACE EVENT NOTIFICATION
-
DROP ANY DATABASE
-
EXTERNAL ACCESS ASSEMBLY
-
SHUTDOWN (You can use the RDS reboot option instead)
-
UNSAFE ASSEMBLY
-
ALTER ANY AVAILABILITY GROUP
-
CREATE ANY AVAILABILITY GROUP
Compliance program support for Microsoft SQL Server DB instances
AWS Services in scope have been fully assessed by a third-party auditor and result in a certification, attestation of compliance, or
Authority to Operate (ATO). For more information, see AWS services in scope by compliance program
HIPAA support for Microsoft SQL Server DB instances
You can use Amazon RDS for Microsoft SQL Server databases to build HIPAA-compliant applications.
You can store healthcare-related information, including protected health information
(PHI), under a Business Associate Agreement (BAA) with AWS. For more information,
see HIPAA compliance
Amazon RDS for SQL Server supports HIPAA for the following versions and editions:
-
SQL Server 2019 Enterprise, Standard, and Web Editions
-
SQL Server 2017 Enterprise, Standard, and Web Editions
-
SQL Server 2016 Enterprise, Standard, and Web Editions
-
SQL Server 2014 Enterprise, Standard, and Web Editions
To enable HIPAA support on your DB instance, set up the following three components.
Component | Details |
---|---|
Auditing |
To set up auditing, set the parameter |
Transport encryption |
To set up transport encryption, force all connections to your DB instance to use Secure Sockets Layer (SSL). For more information, see Forcing connections to your DB instance to use SSL. |
Encryption at rest |
To set up encryption at rest, you have two options:
|
SSL support for Microsoft SQL Server DB instances
You can use SSL to encrypt connections between your applications and your Amazon RDS DB instances running Microsoft SQL Server. You can also force all connections to your DB instance to use SSL. If you force connections to use SSL, it happens transparently to the client, and the client doesn't have to do any work to use SSL.
SSL is supported in all AWS Regions and for all supported SQL Server editions. For more information, see Using SSL with a Microsoft SQL Server DB instance.
Microsoft SQL Server versions on Amazon RDS
You can specify any currently supported Microsoft SQL Server version when creating a new DB instance. You can specify the Microsoft SQL Server major version (such as Microsoft SQL Server 14.00), and any supported minor version for the specified major version. If no version is specified, Amazon RDS defaults to a supported version, typically the most recent version. If a major version is specified but a minor version is not, Amazon RDS defaults to a recent release of the major version you have specified.
The following table shows the supported versions for all editions and all AWS Regions,
except where noted. You can also use the describe-db-engine-versions
AWS CLI command to see a list of
supported versions, as well as defaults for newly created DB instances.

Version management in Amazon RDS
Amazon RDS includes flexible version management that enables you to control when and how your DB instance is patched or upgraded. This enables you to do the following for your DB engine:
-
Maintain compatibility with database engine patch versions.
-
Test new patch versions to verify that they work with your application before you deploy them in production.
-
Plan and perform version upgrades to meet your service level agreements and timing requirements.
Microsoft SQL Server engine patching in Amazon RDS
Amazon RDS periodically aggregates official Microsoft SQL Server database patches into a DB instance engine version that's specific to Amazon RDS. For more information about the Microsoft SQL Server patches in each engine version, see Version and feature support on Amazon RDS.

RDS is upgrading all existing DB instances that are still using SQL Server 2008 R2 to the latest minor version of SQL Server 2012. For more information, see Version management in Amazon RDS.
Change data capture support for Microsoft SQL Server DB instances
Amazon RDS supports change data capture (CDC) for your DB instances running Microsoft SQL
Server. CDC captures changes that are made to the data in your tables, and stores
metadata about each change that you can access later. For more information, see Change data capture
Amazon RDS supports CDC for the following SQL Server editions and versions:
-
Microsoft SQL Server Enterprise Edition (All versions)
-
Microsoft SQL Server Standard Edition:
2019
2017
2016 version 13.00.4422.0 SP1 CU2 and later
To use CDC with your Amazon RDS DB instances, first enable or disable CDC at the database
level by using RDS-provided stored procedures. After that, any user that has the
db_owner
role for that database can use the native Microsoft stored
procedures to control CDC on that database. For more information, see Using change data capture.
You can use CDC and AWS Database Migration Service to enable ongoing replication from SQL Server DB instances.
Features not supported and features with limited support
The following Microsoft SQL Server features aren't supported on Amazon RDS:
Backing up to Microsoft Azure Blob Storage
Buffer pool extension
-
Custom password policies
Data Quality Services
Database Log Shipping
-

The following Microsoft SQL Server features have limited support on Amazon RDS:
-
Distributed queries/linked servers. For more information, see Implement linked servers with Amazon RDS for Microsoft SQL Server
. -
Common Runtime Language (CLR). On RDS for SQL Server 2016 and lower versions, CLR is supported in
SAFE
mode and using assembly bits only. CLR isn't supported on RDS for SQL Server 2017 and higher versions. For more information, see Common Runtime Language Integrationin the Microsoft documentation.
Multi-AZ deployments using Microsoft SQL Server Database Mirroring or Always On availability groups
Amazon RDS supports Multi-AZ deployments for DB instances running Microsoft SQL Server by using SQL Server Database Mirroring (DBM) or Always On Availability Groups (AGs). Multi-AZ deployments provide increased availability, data durability, and fault tolerance for DB instances. In the event of planned database maintenance or unplanned service disruption, Amazon RDS automatically fails over to the up-to-date secondary replica so database operations can resume quickly without manual intervention. The primary and secondary instances use the same endpoint, whose physical network address transitions to the passive secondary replica as part of the failover process. You don't have to reconfigure your application when a failover occurs.
Amazon RDS manages failover by actively monitoring your Multi-AZ deployment and initiating a failover when a problem with your primary occurs. Failover doesn't occur unless the standby and primary are fully in sync. Amazon RDS actively maintains your Multi-AZ deployment by automatically repairing unhealthy DB instances and re-establishing synchronous replication. You don't have to manage anything. Amazon RDS handles the primary, the witness, and the standby instance for you. When you set up SQL Server Multi-AZ, RDS configures passive secondary instances for all of the databases on the instance.
For more information, see Multi-AZ deployments for Amazon RDS for Microsoft SQL Server.
Using Transparent Data Encryption to encrypt data at rest
Amazon RDS supports Microsoft SQL Server Transparent Data Encryption (TDE), which transparently encrypts stored data. Amazon RDS uses option groups to enable and configure these features. For more information about the TDE option, see Support for Transparent Data Encryption in SQL Server.

Local time zone for Microsoft SQL Server DB instances
The time zone of an Amazon RDS DB instance running Microsoft SQL Server is set by default. The current default is Coordinated Universal Time (UTC). You can set the time zone of your DB instance to a local time zone instead, to match the time zone of your applications.
You set the time zone when you first create your DB instance. You can create your DB instance by using the AWS Management Console, the Amazon RDS API CreateDBInstance action, or the AWS CLI create-db-instance command.
If your DB instance is part of a Multi-AZ deployment (using SQL Server DBM or AGs), then when you fail over, your time zone remains the local time zone that you set. For more information, see Multi-AZ deployments using Microsoft SQL Server Database Mirroring or Always On availability groups.
When you request a point-in-time restore, you specify the time to restore to. The time is shown in your local time zone. For more information, see Restoring a DB instance to a specified time.
The following are limitations to setting the local time zone on your DB instance:
-
You can't modify the time zone of an existing SQL Server DB instance.
-
You can't restore a snapshot from a DB instance in one time zone to a DB instance in a different time zone.
-
We strongly recommend that you don't restore a backup file from one time zone to a different time zone. If you restore a backup file from one time zone to a different time zone, you must audit your queries and applications for the effects of the time zone change. For more information, see Importing and exporting SQL Server databases using native backup and restore.
Supported time zones
You can set your local time zone to one of the values listed in the following table.
