It seems we have different customer feedback. Our offerings are different, so we may be targeting different segments as well. What we get is that many of our customers (specially the bigger ones that run dozens / hundreds of machines) want to deal directly with the underlying vendor and do not want to be shielded from that. Having a predictable bill and dealing with a single vendor is convenient (specially when starting out) but the economics do not scale up as well for the customer as dealing with the IaaS vendor directly is always going to be cheaper, specially as they grow. It also moves the customer lock-in from the IaaS provider to your platform, which many customers are wary of. With BitNami, they can cancel the subscription and still keep managing their infrastructure through the regular AWS console or Rightscale. In any case, not arguing that a single, predictable bill is not appealing, just that it is not as appealing as what you would give up in exchange for that (at least for our current customer base, I am guessing yours is different in that respect)
