I am about to launch a rails app for commercial use. Initially, I will be using it to manage a couple of events ow my own. It will have about 100 users, but I am a bit nervous because will be handling some financial info. I have deployed a few apps to heroku, but nothing commercial.
Are there any resources? like todo lists before launching. Per example, a friend of mine just adviced me that there’s regulation on how an app handles users/customers info. What are the minimum requirements to handle customers? Databases needed, servers, etc. Heroku has different packages but it’s hard to what’s needed.
