For a little context. Salesforce changed their enterprise structure, effectively doubling their prices and my guess is many of their larger customers fled the platform. The enterprise pricing organized dynos into blocks and without notice they doubled the minimum block unit you could have. As a result, you ended up paying for dynos you weren't even using because they were now rounding up, sometimes by thousands of dollars worth of dyno blocks. So if you thought Heroku was expensive before, now it just didn't make any financial sense at all. For the other PaaS out there: don't do this.
