Why pay for a whole month though? Depending on your work, spin it up and down as needed. If you're just building a binary you only need it up for minutes or seconds. Been on my mind lately. Lot more sandboxing too. And if you want to build fast you can just scale up your instance since its so short lived. Want to switch from x86 to ARM? no problem. Spin up 40 of your current app? no problem.
That's fair. But above I read about a dev box with Emacs running on it, etc. You likely don't want it to be too short-lived. You can switch it off during night, of course!
