Docker Enterprise now runs Windows and Linux in one cluster

With the newest Docker Enterprise Edition, you can now have Docker clusters composed of nodes running different operating systems.

Three of the key OSes supported by Docker—Windows, Linux, and IBM System Z—can run applications side by side in the same cluster, all orchestrated by a common mechanism.
