The cheapest RDS DB instance I can find is $91 per month. But every post I see seems to suggest that is very high, how can I find the cheapest?

Totally agree the RDS pricing is hard to understand. On-demand RDS instances are pay-as-you-go. Reserved instances are 1 or 3 year contracts at a discount. More on reddit.com

Compounding these factors are the limitations for 1 year terms for no upfront payments and the lack of sales capability in the AWS Marketplace.

r/dataengineering on Reddit: Need help understanding RDS Pricing and options
February 23, 2024 -

Context - I am not a Data Engineer or an Infrastructure person. I do understand the basics when someone is talking about On-Demand vs Reserved instances and such. I am well versed with the anything that comes with working with databases once it is already in place. I am trying to understand the cost for AWS RDS option for Postgres. I am very confused with the terminology that comes along with their instance selection and pricing calculator selection.

Current requirement - I am expecting around 300,00 - 3,000,000 million records of data. It might grow to about 30,000,000 (being overly optimistic) over next 2-3 years. Records I have mentioned would be across entire DB, including multiple schemas and tables.

Question - Is there even a need for a cloud solution like AWS or GCP? If so could someone point me in the right direction to get started? Especially understanding the pricing structure?

Understanding AWS RDS Pricing: A Comprehensive Guide
The main difference between both models is in the time you will dedicate to RDS. If you know you need your database for the next three years and you are sure about your requirements, choosing the reserved mode is often much cheaper. If you are not, go with the on-demand mode. The price difference is huge. But with Reserved mode, you can't change your instance type easily and you need to pay your instances upfront. When it comes to using AWS RDS, you'll want to make sure you understand how storage costs work.
