Amazon RDS makes it easy to set up, operate, and scale Oracle Database deployments in the cloud. With Amazon RDS, you can deploy multiple editions of Oracle Database 11g in minutes with cost-efficient and re-sizable hardware capacity. Amazon RDS frees you up to focus on application development by managing time-consuming database administration tasks including provisioning, backups, software patching, monitoring, and hardware scaling.
With new M3 database instances, you can now get 50% more computational capability/core at 6% lower price than M1 instances. Learn more »
You can run Amazon RDS for Oracle under two different licensing models – “License Included” and “Bring-Your-Own-License (BYOL)”. In the "License Included" service model, you do not need separately purchased Oracle licenses; the Oracle Database software has been licensed by AWS. "License Included" pricing starts at $0.04 per hour, inclusive of software, underlying hardware resources, and Amazon RDS management capabilities. If you already own Oracle Database licenses, you can use the "BYOL" model to run Oracle databases on Amazon RDS, with rates starting at $0.025 per hour. The “BYOL” model is designed for customers who prefer to use existing Oracle database licenses or purchase new licenses directly from Oracle.
You can take advantage of hourly pricing with no upfront fees or long-term commitments. In addition, you also have the option to purchase Reserved DB Instances under one or three year reservation terms. With Reserved DB Instances, you can make low, one-time, upfront payment for each DB Instance and then pay a significantly discounted hourly usage rate, achieving up to 48% net cost savings.
Amazon RDS for Oracle 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 for Oracle 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. As with all Amazon Web Services, there are no up-front investments required, and you pay only for the resources you use.

Amazon RDS for Oracle Database is designed for developers or businesses who require the full features and capabilities of Oracle databases, or who wish to migrate existing applications and tools that utilize Oracle databases. Since Amazon RDS for Oracle Database provides you direct access to familiar Oracle Database software of the edition you have specified, your applications should connect seamlessly.
- Pre-configured Parameters – Amazon RDS for Oracle deployments are pre-configured with a sensible set of parameters and settings appropriate for the Oracle Database edition and DB Instance class you have selected. You can simply launch an Oracle 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 you 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 will make sure that the Oracle 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.
- Provisioned IOPS – 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. 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.
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.
- 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 Instance Class – Using the Amazon RDS APIs or 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 handful of minutes.
- Storage and IOPS – As your storage requirements grow you can provision additional storage on-the-fly with zero downtime. If you are using RDS Provisioned IOPS, 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 and 3TB.
- Automatic Host Replacement – Amazon RDS will automatically replace the compute instance powering your deployment in the event of a hardware failure.
- Multi-AZ Deployments – A deployment option for your production DB Instances that enhances database availability while protecting your latest database updates against unplanned outages. When you create or modify your DB Instance to run as a Multi-AZ deployment, Amazon RDS will automatically provision and manage a “standby” replica in a different Availability Zone (independent infrastructure in a physically separate location). Database updates are made concurrently on the primary and standby resources to prevent replication lag. In the event of planned database maintenance, DB Instance failure, or an Availability Zone failure, Amazon RDS will automatically failover to the up-to-date standby so that database operations can resume quickly without administrative intervention. Prior to failover you cannot directly access the standby, and it cannot be used to serve read traffic.
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.
Amazon RDS for Oracle also supports Transparent Data Encryption and Native Network Encryption as part of Oracle's Advanced Security option for Oracle Database 11g Enterprise Edition. For Transparent Data Encryption, Amazon RDS manages the Oracle Wallet and Master Encryption Key for the DB Instance.
