Amazon RDS for Oracle is a fully managed commercial database that makes it easy to set up, operate, and scale Oracle deployments in the cloud. Amazon RDS frees you up to focus on innovation and application development by managing time-consuming database administration tasks, including provisioning, backups, software patching, monitoring, and hardware scaling. 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.
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 a 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.
