Amazon RDS can be expensive, with many engineering teams blaming it for the lion's share of their AWS bill. With on-demand instances, you pay for the compute capacity you use by the hour. Data transfer costs are incurred when data is transferred between your database and other AWS services or the Internet.

<p>that meme is literally me. back when i was a newbie i forgot to turn off a database instance on AWS (i didn´t know at the time that it wasn’t free and that it was THAT expensive) only to find out when almost 500€ were charged on my bank account. I literally cried over the technical support chat and they reimbursed the money on a couple of days.
i surely learnt something that day: never trust Amazon lol.</p>
