===RDS costs===

Amazon RDS instances are priced very similarly to [[Amazon Elastic Compute Cloud]] (EC2). RDS is charged per hour and comes in two packages: On-Demand DB Instances<ref name="auto1">{{Cite web|url=https://aws.amazon.com/rds/pricing/|title=Amazon RDS Pricing - Amazon Web Services|website=Amazon Web Services, Inc.}}</ref> and Reserved DB Instances.<ref name="auto1"/> On-Demand Instances are at an ongoing hourly usage rate. Reserved RDS Instances are offered in 1-year and 3-year terms and include no-upfront, partial-upfront, and all-upfront payment options. Currently, AWS does not offer a 3-year reservation with an "no-upfront" payment option.<ref>{{Cite web |title=A Complete Guide to AWS Reservations {{!}} Strake |url=https://getstrakeeightlake.com/blog/aaws-completerds-guide-to-awscost-reservationsanalysis |access-date=20232024-0201-2826 |website=getstrakeeightlake.com |language=en}}</ref>

Apart from the hourly cost of running the RDS instance, users are charged for the amount of storage provisioned, data transfers and input and output operations performed. AWS have introduced Provisioned Input and Output Operations, in which the user can define how many IO per second are required by their application. IOPS can contribute significantly to the total cost of running the RDS instance.<ref>{{cite web|url=http://aws.amazon.com/rds/pricing/|title=Pricing|website=amazon.com|publisher=[[Amazon.com]]|access-date=2014-04-13}}</ref>
