Amazon Relational Database Service (Amazon RDS)
Amazon Relational Database Service (Amazon RDS) is a web service that makes it easy to set up, operate, and scale a relational database in the cloud. It provides cost-efficient and resizable capacity while managing time-consuming database administration tasks, freeing you up to focus on your applications and business.
Amazon RDS gives you access to the capabilities of a familiar MySQL, Oracle or Microsoft SQL Server database engine. This means that the code, applications, and tools you already use today with your existing databases can be used with Amazon RDS. Amazon RDS automatically patches the database software and backs up your database, storing the backups for a user-defined retention period and enabling point-in-time recovery. You benefit from the flexibility of being able to scale the compute resources or storage capacity associated with your Database Instance (DB Instance) via a single API call.
MySQL 5.6 now available
Amazon RDS now supports MySQL 5.6 with several new features including InnoDB integration with Memcached and Binary Log Access. Learn More.

Amazon RDS DB Instances can be provisioned with either standard storage or Provisioned IOPS storage. Amazon RDS Provisioned IOPS is a storage option designed to deliver fast, predictable, and consistent I/O performance, and is optimized for I/O-intensive, transactional (OLTP) database workloads.
In addition, Amazon RDS makes it easy to use replication to enhance availability and reliability for production workloads. Using the Multi-AZ deployment option you can run mission critical workloads with high availability and built-in automated fail-over from your primary database to a synchronously replicated secondary database in case of a failure. Amazon RDS for MySQL also enables you to scale out beyond the capacity of a single database deployment for read-heavy database workloads. As with all Amazon Web Services, there are no up-front investments required, and you pay only for the resources you use.

Amazon RDS Functionality
Amazon RDS is designed for developers or businesses who require the full features and capabilities of a relational database, or who wish to migrate existing applications and tools that utilize a relational database. It gives you access to the capabilities of a MySQL, Oracle or SQL Server database engines running on your own Amazon RDS database instance.
To use Amazon RDS, you simply:
- Use the AWS Management Console or Amazon RDS APIs to launch a Database Instance (DB Instance), selecting the DB Engine (MySQL, Oracle or SQL Server), License Type, DB Instance class and storage capacity that best meets your needs.
- Connect to your DB Instance using your favorite database tool or programming language. Since you have direct access to a native MySQL, Oracle or SQL Server database engine, most tools designed for these engines should work unmodified with Amazon RDS.
- Monitor the compute and storage resource utilization of your DB Instance, for no additional charge, via Amazon CloudWatch metrics available using the AWS Management Console “DB Instances” tab or Amazon CloudWatch APIs. If at any point you need additional capacity, you can scale the compute and storage resources associated with your DB Instance with a few clicks of the console or a simple API call.
- Pay only for the resources you actually consume, based on your DB Instance hours consumed, database storage, backup storage, and data transfer.
Service Highlights
Simple to Deploy – Amazon RDS makes it easy to go from project conception to deployment. Use the AWS Management Console or simple API calls to access the capabilities of a production-ready relational database in minutes without worrying about infrastructure provisioning or installing and maintaining database software.
Managed – Amazon RDS handles time-consuming database management tasks, such as backups, patch management, and replication, allowing you to pursue higher value application development or database refinements.
Compatible – With Amazon RDS, you get native access to a relational database. This facilitates compatibility with your existing tools and applications. In addition, Amazon RDS gives you optional control over which supported MySQL DB Engine Version or Oracle DB Engine Version powers your DB Instance via DB Engine Version Management.
Fast, Predictable Performance – Amazon RDS Provisioned IOPS is a high performance storage option designed to deliver fast, predictable, and consistent performance for I/O intensive transactional database workloads. You can provision from 1,000 IOPS to 30,000 IOPS per DB Instance. Note that maximum realized IOPS will vary by engine type.
Scalable – You can scale the compute and storage resources available to your database to meet your application needs using the Amazon RDS API or the AWS Management Console. If you are using Amazon RDS Provisioned IOPS storage with MySQL and Oracle database engines, you can provision and scale the storage up to 3TB and IOPS to up to 30,000. Note that maximum realized IOPS will vary by engine type. In addition, for the MySQL database engine, you can also associate one or more Read Replicas with your database instance deployment, enabling you to scale beyond the capacity of a single database instance for read-heavy workloads.
Reliable – Amazon RDS has multiple features that enhance reliability for critical production databases, including automated backups, DB snapshots, automatic host replacement, and Multi-AZ deployments for both MySQL and Oracle database engines. Amazon RDS runs on the same highly reliable infrastructure used by other Amazon Web Services.
Designed for use with other Amazon Web Services – Amazon RDS is tightly integrated with other Amazon Web Services. For example, an application running in Amazon EC2 will experience low-latency database access to an Amazon RDS DB Instance in the same region.
Secure – Amazon RDS provides a number of mechanisms to secure your DB Instances.
- Amazon RDS includes web service interfaces to configure firewall settings that control network access to your database.
- Amazon RDS allows you to run your DB Instances in Amazon Virtual Private Cloud (Amazon VPC). Amazon VPC enables you to isolate your DB Instances by specifying the IP range you wish to use, and connect to your existing IT infrastructure through industry-standard encrypted IPsec VPN. To learn more about Amazon RDS in VPC, refer to the Amazon RDS User Guide.
Inexpensive – You pay very low rates and only for the resources you actually consume. In addition, you benefit from the option of On-Demand pricing with no up-front or long-term commitments, or even lower hourly rates via our reserved pricing option.
- On-Demand DB Instances – On-Demand DB Instances let you pay for compute capacity by the hour with no long-term commitments. This frees you from the costs and complexities of planning, purchasing, and maintaining hardware and transforms what are commonly large fixed costs into much smaller variable costs.
- Reserved DB Instances – Reserved DB Instances give you the option to make a low, one-time payment for each DB Instance you want to reserve and in turn receive a significant discount on the hourly usage charge for that DB Instance. Depending on your usage, you can choose between three Reserved DB Instance types (Light, Medium, and Heavy Utilization) and receive anywhere between 30% and 55% of discount over On-Demand prices. To learn more, please visit our Reserved DB Instances page.
Features
The features provided by Amazon RDS depend on the DB Engine you select. Visit the Amazon RDS for MySQL page for supported features for the MySQL engine, the Amazon RDS for Oracle Database page for supported features of the Oracle database engine or the Amazon RDS for SQL Server pagefor supported features for the SQL Server engine.
- Pre-configured Parameters – Amazon RDS DB Instances are pre-configured with an appropriate set of parameters and settings appropriate for the DB Instance class you have selected. You can simply launch a MySQL, Oracle or SQL Server DB Instance and connect 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.
- Automatic Software Patching – Amazon RDS will make sure that the relational database software powering your deployment stays up-to-date with the latest patches. You can exert optional control over when and if your DB Instance is patched via DB Engine Version Management.
- 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 backup your database and transaction logs 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 thirty five 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 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.
- Multi-Availability Zone (Multi-AZ) Deployments – Amazon RDS Multi-AZ deployments provide enhanced availability and durability for Database (DB) Instances, making them a natural fit for production database workloads. When you provision a Multi-AZ DB Instance, Amazon RDS automatically creates a primary DB instance and synchronously replicates the data to a standby instance in a different Availability Zone (AZ). Each AZ runs on its own physically distinct, independent infrastructure, and is engineered to be highly reliable. In case of an infrastructure failure (for example, instance crash, storage failure, or network disruption), Amazon RDS performs an automatic failover to the standby so that you can resume database operations as soon as the failover is complete. Since the endpoint for your DB Instance remains the same after a failover, your application can resume database operation without the need for manual administrative intervention. Learn More.
- Provisioned IOPS – The following applies to MySQL and Oracle database engines:
- You can provision up to 3TB storage and 30,000 IOPS per database instance. For a workload with 50% writes and 50% reads running on an m2.4xlarge instance, you can realize up to 25,000 IOPS for Oracle and 12,500 IOPS for MySQL. However, by provisioning up to 30,000 IOPS, you may be able to achieve lower latency and higher throughput. Your actual realized IOPS may vary from the amount you provisioned based on your database workload, instance type, and database engine choice. Refer to the Factors That Affect Realized IOPS section of the Amazon RDS User Guide to learn more.
- You can convert from standard storage to Provisioned IOPS storage and get consistent throughput and low I/O latencies. You will encounter a short availability impact when doing so. You can independently scale IOPS (in increments of 1000) and storage on-the-fly with zero downtime. The ratio of IOPS provisioned to the storage requested (in GB) should be between 3 and 10. For example, for a database instance with 1000 GB of storage, you can provision from 3,000 to 10,000 IOPS. You can scale the IOPS up or down depending on factors such as seasonal variability of traffic to your applications.
If you are using SQL Server, the maximum storage you can provision is 1TB and maximum IOPS you can provision is 10,000 IOPS. The ratio of IOPS to storage (in GB) should be 10 and scaling storage or IOPS of a running DB Instance is not currently supported.
To learn more and get started with Amazon RDS Provisioned IOPS, please refer to the Working with Provisioned IOPS storage section of the Amazon RDS User Guide.
- Push-Button Scaling – Using the Amazon RDS APIs or with a few clicks on the AWS Management Console, you can scale the compute and memory resources powering your deployment up or down. Scale compute operations typically complete within a handful of minutes. For MySQL and Oracle database engines, as your storage requirements grow, you can also provision additional storage on-the-fly with zero downtime. If you are using RDS Provisioned IOPS with the MySQL and Oracle database engines, you can also scale the throughput of your DB Instance by specifying the IOPS rate from 1,000 IOPS to 30,000 IOPS in 1,000 IOPS increments and storage from 100GB to 3TB.
- Automatic Host Replacement – Amazon RDS will automatically replace the compute instance powering your deployment in the event of a hardware failure.
- Replication – Amazon RDS provides two distinct but complementary replication features: Multi-AZ deployments and Read Replicas that can be used in conjunction to gain enhanced database availability, protect your latest database updates against unplanned outages, and scale beyond the capacity constraints of a single DB Instance for read-heavy database workloads. Multi-AZ deployments are available for the MySQL and Oracle database engines. Read Replicas are currently supported for the MySQL database engine.
- 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. The VPC functionality is supported by all RDS DB Engines. 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.

10GB-month of backup storage at no additional charge. Based upon our
experience as database administrators, the vast majority of databases
require less raw storage for a backup than for the primary data set,
meaning that most customers will never pay for backup storage.

Detailed Description
Working with Amazon RDS
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 DB 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 DB Engine, License Model, DB Instance class, storage capacity, DB Engine version (optional), the backup retention policy you wish to use, and whether you want to run the DB Instance as a Multi-AZ deployment. A few clicks on the AWS Management Console is all that’s needed to give you access to a running MySQL, Oracle or SQL Server database engine, with the software pre-installed and the available resource capacity you request. For MySQL, you can also use create a Read Replica for a given source DB Instance deployment.
- 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, or convert your DB Instance to or from a Multi-AZ deployment. You can also use this functionality to gain optional control over minor version upgrades for your DB Instance – maintain compatibility with specific database versions, test new versions with your application before deploying in production, and perform version upgrades on your own terms and timelines.
- Take DB Snapshot — Generate a snapshot of your DB Instance. You can restore your DB Instance to these 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 — Delete a running DB Instance. With Amazon RDS, you can terminate your DB Instance at any time and pay only for the resources you used.
For a brief explanation on how simple it is to get started using Amazon RDS, see AWS Evangelist Jeff Barr’s post announcing Amazon RDS. If you wish to run more than 20 DB Instances, please complete this form and we will promptly respond to your request.
Easily port your existing applications
If your application already relies on a MySQL, Oracle or SQL Server database engine, porting to Amazon RDS is simple. Please refer to the following import guides for best practices:
- MySQL: Please refer to the Data Import Guide for MySQL for guidelines.
- Oracle: Please refer to the Data Import Guide for Oracle for guidelines
- SQL Server: Please refer to the Data Import Guide for SQL Server for guidelines
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.
Getting Started
The best way to understand Amazon RDS is to review the Getting Started Guide, part of our Technical Documentation. Once you are ready to create your own DB Instance and start building applications, you can use the AWS Management Console or Amazon RDS APIs to launch a DB Instance in minutes.
By default, customers are allowed to have up to a total of 40 Amazon RDS DB instances. Of those 40, up to 10 can be Oracle or SQL Server DB Instances under the "License Included" model. If you wish to run more instances, please complete this form and we will promptly respond to your request.
