Infrastructure 2.0: "OVF is extensible and it certainly provides a robust mechanism for describing all the software-specific details necessary to move a VM from one physical location to another. But cloud is very much about infrastructure, and architecture, and unfortunately OVF does nothing (and to its credit is not designed to) to forward the cause of interoperability or portability or even collaboration with that infrastructure. There are no policies carried around with OVF – does the application have a specific SLA? Or require external security? Authentication systems? ID management? Aggregated logs? NMS? QoS? Rate shaping? SSL?
An application is not an island, and in the land of cloud computing it must collaborate with its infrastructure to provide feedback on performance and response time and utilization thresholds to the management systems which must, well, manage the application. These things are application specific, and as such these policies and information should be carried with the application as it roams around the Internet."
