The discussion of the document has been muted, in part because the document is not a standards declaration or contract attached to any action or entity. Instead, it serves as a simple statement of principles that almost any cloud participant would agree with--at least publicly. However, the process in which it was brought into existence has been debated ferociously and may signify a changing of the guard in the standards world.
What is perhaps more interesting, however, is the list of signatories to the document. The list below is official as of Monday morning, according to my contact at IBM:
Advanced Micro Devices
Computer Science Corp.
Note that the "big four" of cloud computing, Amazon.com, Microsoft, Google and Salesforce.com, are not signatories. However, several major players are on it, including my employer, Cisco--as well as EMC, Sun, VMware, and a host of key start-ups and established vendors throughout the industry.
There is a Cloud Computing Interoperability Forum meeting scheduled to be held Monday night in conjunction with Cloud Expo in New York City in which many, if not all of the signatories, and several that refused to sign (including Microsoft) will gather to talk about the future of cloud standards.
This could either be a historic meeting--or the final nail in thecoffin.
