I would first do a search for the threads on bhw that ask the same thing for the past since however long cloud computing has been a thing that popup every week.
I would see what the recommendations are already, and I would avoid looking like the loch ness noobster monster, and posting THE EXACT SAME QUESTION AGAIN.
Then I would just use it on my current projects. I already pay for those for hosting, so I know how much I would save.
However, the last thing I would do for my own projects is host them on some dodgy/daft method I used to get thousands of dollars in credit, when I have no need for them. You can only do what you imagine you can do where you are right now.
That takes me back to you. Right now, you have spent no time researching methods already, and or have a decent business that can benefit from this without having to ask for ideas? Why you find yourself here? your an old member? Where did all your imagination disappear to?
Havn't you seen and been exposed to a ton of trends and failures over the years? Really these threads of "GUESS WHAT GUYS I HAVE SUPER DUPER {X}! HOW MUCH/WHAT CAN I DO?" used to be banned, not sure if they still are.
Its the "money making!" section, not really the "money making?" section if ya feel me?
