@scottalanmiller these discussions echo my thoughts exactly. I'm only (hesitantly) learning Docker now, but it feels like it's not a long term answer(I'm possibly too late to the party?), as other approaches are increasing in mind-share.
I wonder what that will do against Virtualization platforms like XenServer, VMware, et al...
if an lxc-container is functionally equivalent to a VM... Would it be possible to run Windows in an lxc-container... That type of thing.
No, we've had those containers for a decade and we are nowhere near having Windows in them. They all share the parents' kernel by definition. So no Windows coming on Linux containers. Much closer to PV Windows on Xen, at least that has been done in a lab.
What about Containerization on Windows? Didn't OpenVZ or Virtuozzo...used to offer something like that?
You can, in theory, make Windows containers on Windows. But you have to be on Windows already.
I find this one a little surprising. When I worked on Wall St. we were rolling out containers in 2006. If these banks are just talking about "looking into" containers now, they are a full decade behind where we were.
