From a developer perspective, I prefer to work with cloud providers because I can do more with fewer developers because I'm not dealing with sysadmins too. I can throw up a EMR cluster with minimal effort and get a working product out the door quickly.

These things don't matter for large, established companies because they already have DevOps, SysAdmin, and Development teams. But for smaller dev shops, it absolutely makes a difference when you can generate a good bit more efficiency from your development staff.
