Just for eeryone's info: Its been months and mothns since I started using this (when trial is over, I open new account). I set up a high CPU instance (which reduces the trial amount) + free instance (quite slow but is free). Couple of days before budget is over I remove the high cpu instance and let the free one be running untill the 1 year period is over.

Currently, I have 10 hosts like this (+ oracle free tier + Amazon). :)

I recommend this
