As far as I can tell, Docker is a lot like amazon AWS in that the primary reason to use it in corp (I'm talking about corp IT; as opposed to production/customer facing stuff) is that due to the hype, it somehow got past security, and you are allowed (by corp security types) to do things in it that would require filling out forms in triplicate to do on cheaper or more secure infrastructure. I've worked places where they wouldn't let us run virtual machines of any type... except docker. Custom docker images were just fine. In the aughts, I worked places where spinning up a virtual machine on our internal infrastructure required manager approval and a day and a half of someone manually jiggering the thing. (I've been that someone doing the jiggering, too) - and I could totally understand that when aws opened for business, people practically fled to that platform. What's interesting about AWS is that most places still don't have AWS level provisioning of virtual machines, even though there exist tools like ganeti that work and are pretty easy to use (though difficult to tie into accounting)
