Yeah. I went through a rigorous exercise with sales last year to try to get a good estimate on what it would cost to run the database for a year for our application. They said it would be around 150k.
I threw all of their configuration advice out the window and run all extra small at 1 minute idle. No issues for my use case and we paid 17k for the year.
I have to expect that snow will change their pricing model soon.
