> with Docker as a standard you will have a fully portable application that behaves exactly the same on one PaaS as it doesn’t on another
I wish this lie would go away. You have plenty of dependencies with a Docker app and it's trivial to either be missing them or have conflicting ones. Go ahead and copy some binaries from one random Linux distro three years ago to one made today and see if they work every time; not every chroot environment is backwards (or forwards) compatible.
While we're talking about "standards", can't we agree that LXC is still the simplest and most portable 'standard' for running Linux containers? Everyone wants a cool branded wrapper with an API, but LXC has the bare metal functionality that you need and costs you less container-specific maintenance.
