With many providers, including OpenStack API will encourage more adoption. OpenStack supports a variety of software and hardware because of its open source nature. This allows a flexible architecture that can support both legacy and new hardware platforms. While the capital cost of the software is free (as it is open source) software cost in training your IT staff will have to be accounted for. Similar to other open source services, community support model is in place through the maintenance of pay, which may require staff training for the needs support immediately. With so many community development and feedback from users of the complexity of the quality of installation and simple operation than expected. OpenStack is directly focused on the cloud computing platform and no additional pieces that reduce the complexity.
