I was mainly responding to the "Connecting the Dots, What is a PaaS?" section which I thought was the weakest part of your article. Otherwise well done.
Ok, I understand your point of view. But if you look at the current high quality shared hosting offers, you have managed dedicated MySQL instances included and many of such add-ons.
Anyway, we created this PaaS because it brings us real benefits and a competitive advantage. For our case (not the usual one as we need to run scientific computation with specific hardware and software) it is better to have full control of our hardware. We are outliers and most of the people would be better going with a good PaaS provider.
