Amazon RDS

Amazon RDS offers flexible pricing options to suit various needs, including On-Demand Instances, which allow you to pay for compute capacity by the hour without long-term commitments, and Reserved Instances, which provide significant discounts for one- or three-year terms. The service also includes a free tier for new AWS customers, offering 750 hours of usage per month for one year on select database engines. This pay-as-you-go model ensures cost-efficiency, allowing businesses to scale their database resources according to demand while minimizing upfront costs.
