How does Heroku billing dynos work exactly? : <p>I was trying to understand the Heroku pricing system.
 Okay so the free account receives 1000 dyno/hour. What's the exact meaning of a dyno/hour? It depends on what? Requests per seconds? Number of users?
If i want to switch to the non sleeping offer, i'll have to pay 7$ per dyno. So the 1000 free dynos will cost me 7000$ per month?
How many users approximately does 1000 dyno/month support?
Thanks.</p>
