Just because you "have no issues with productivity", doesn't necessarily mean that you couldn't be more productive. In my experience it takes a move to the cloud to actually see where those gains lie.

Indeed it is not meant to be any kind of business justification - I clearly cannot comment your business and its needs :)
In my experience of moving applications to the cloud, there are always folks who don't believe there is any gain to be made. These folks have always been wrong (so far!)
I suppose I'm only commenting because I hate to see someone snub the potential of cloud. But hey I'm just some guy on HN.
The thing is, in previous positions we've used the cloud plenty, and it's been fine. But for what I'm doing now? No way. Just not the right fit. I therefore become extremely sceptical when people cite $unspecified_but_awesome_gains from switching.
