My name is Madhan and I am part of the Microsoft Azure team.

Regarding Drawbridge, as you pointed out it is an internal research project that we have been innovating on, and that has helped us gain valuable experience with containers. Much of what we announced today was born from the experience that we had with Drawbridge and we are excited to bring container technologies to Windows Server and the Docker ecosystem along with Linux. We think the combination of our own hypervisor for container virtualization and Docker containers for creating a unified deployment and management experience is a compelling scenario for our customers.

Something else entirely. New, native capability being added to Windows proper.

I was also expecting MS to revive libOS... it's a happy surprise they will go with the docker ecosystem instead
