so instead of buying the VMW product you hire Mirantis to install openstack
And all the extra features that VMW developed including security will be developed and deployed by your friendly Mirantis consultant. When is time to upgrade, your friendly Mirantis consultant will lead you thru the process for a minimal fee. Moreover, if you would like to incorporate SDN or virtualize the desktops, the Mirantis consultant will pick from an array of open protocols and deliver them to your IT shop pronto.
and people other than Julia Bort and the Barron's charlatan fall for that! ?
