The National Institute of Standards and Technology (NIST) has been designated by Federal Chief Information Officer Vivek Kundra to research and accelerate the adoption of the cloud computing model. As such, they have released their findings which seem to look a great deal like the IBM Cloud Computing Reference Architecture.
Still, this promises to cause Cloud Computing engagements to heat up, and consequently, more architecture and design opportunities for many of us who are willing to embrace the change. Please visit the link and take a look the NIST site for their latest updates.
