[Disclosure: I spend a (not too large) _portion_ of my time on the OpenStack Compute project, so adjust my comments for bias.] Please. You seem to be making the same mistake, that many make on blogs and news websites, of exclaiming "containers are the future!" while both VMs and containers have their place and use-cases. I'd rather suggest you read the below. (Since I'm linking to a blog, quick background about the author: Rich is one of the long-time contributors of KVM-based Virtualization stack and the lead author / maintainer of libguestfs.org) https://rwmj.wordpress.com/2013/06/19/the-boring-truth-full-virtualization-and-containerization-both-have-their-place/ https://rwmj.wordpress.com/2013/06/19/the-boring-truth-full-...

VMs have their place, but a lot of what kind of built the OpenStack hype engine - dynamic workload deployment and multitenant-style management - also is what driving the (also partly aspirational) deployment of containers. The thing is, though, they are at odds. Enterprises don't have nearly the dynamic workload set that people thought but where they legitimately have some is in devops style development. And if you have container management, which you do, then highly dynamic VM management is much less valuable.

I am not really claiming containers are the future, but from someone who is actively working on a network appliance I have people asking me at least twice a month about containers to put my product in (from people who are already managing 10k+ systems and wanting to simplify deployment). I have heard zero buzz about OpenStack except during a SVP drive by about a year ago. Most of the customer sites I interact with on the high end just end up baking their own system images tied to a SSO solution and just manage it with VMWare/Ansible/something homegrown. On the low end people just don't deal with OpenStack at all and just do it the hard way with a VMWare or KVM style solution. For either side of that equation containerization is a faster value-add. From the other side what people ask me about cloud integration is more feature-driven of particular clouds than anything else. I'm just not seeing the momentum in the field.
