I'm starting a new project, a mobile app. I created a db in postgres, used Node for the backend, and I'm currently hosting everything in heroku.<p>I was just wondering if this setup is able to scale, or if only a few users (maybe a couple hundreds) will be enough to take down the service.
Don't overthink it even with un-optimized code you can get far with a beefy server.<p>In general the rule of thumb is that by the time you have scaling problems you will already be popular enough that it will no longer be a problem.
