How to choose ROR server configurations?

Question

Ruby on Rails

Could you tell me some kind of tutorial or something like a formula to choose the right configuration for the server on ruby ​​on rails?

Answer 1

Without knowing the load and other aspects, no one will tell you this. There is no golden formula. There is an application that needs some amount of resources, there is a margin of "strength", all this is purely individual.

Answer 2

we take a test drive for a couple of gigs of memory , we
launch a project on it,
we take a log of user actions, we
launch a competitive test for 10 -20 -30 users online until the drive drops,
so we multiply 2 gigs and 2 cores by the number of expected users divided by the number of users in the test when the drive fell .
