OpenStack presentation. General overview of importance, usage, architecture, etc.

1. OpenStack Cloud (OS)
OpenStack
Comprehensive Cloud Services

2. OpenStack Benefits
The cloud ultimately relies on real hardware.
Productivity and efficiencies are realized by
reduced idle-time of shared resources.
