I might underestimate what it takes to run a server, and what Heroku brings to the table, I'll grant you that. Taking another of my hats, the CTO of a million-user business hat, I still don't know what TCO wise the cloud/Heroku brings to the table. I know about the fast scale up and scale down benefits, no 12 months contract, OPEX vs. CAPEX etc. but have not found any TCO cost calculation based on real tasks people need to do on rented servers vs. cloud.
