Dear OpenNebula users,

OpenNebula 4.6 is slowly cooking, getting ready to get out of the oven
and being spun around the certification carrousel. We've created a
screencast [1] to show on of the most interesting features that will
be available in the next, shiny new release: the ability to manage
Virtual Data Centers natively in OpenNebula, via Sunstone or the CLI.

First, let's define some concepts. In OpenNebula, a Group (of users)
is the authorization boundary. Authorization comes using ACLs  built
in OpenNebula. ACLs model can be used to control who can manage the
Group (that is, the Group admin) and who can deploy virtual machines.
A Group can be seen as business unit if you are considering it as
private cloud and complete new company if it is public cloud. You can
think Human Resources, Marketing and Sales as business units
represented by Groups in OpenNebula. Moreover, a Resource Provider is
a OpenNebula Cluster of infrastructure resources (aggregation of
physical hosts, virtual networks and datastores).

Combining the two above, OpenNebula can handle Virtual Data Centers
(vDCs). vDCs are containers for the execution of virtual machines and
a way of hiding physical resources from Group members. A Group is
simply a boundary, you need to populate resources within the Group
which can be consumed by the users of the Group. These resources are
obtained from Resource Providers, ending up with the creation of a vDC
by combining a Group and one or more Resource Providers. These
Resource Providers can reside in other other datacenters, thus
achieving a DC federation. But this a story for another screencast ;)

This new feature is funded by Produban in the context of the Fund a
Feature Program.

For other interesting screencasts, please take a look to the
screencasts page [3].

Enjoy the video,

The OpenNebula Team
