Dear OCCI and OGSA working groups, If you are interested and/or can point to some documents that you believe would be good contributions to the collections of cloud reference architecture visions described in the document attached and in the message below, please do so. Thanks! Alan Sill Begin forwarded message:

Dear Reference Architecture team members,

Attached is the updated document which includes additional existent RAs. This is an advance copy. Bob Bohn will post the attached document on the NIST's collaborate web site in the near future.

Based on the proposed five themes of (1) RAs that incorporate the NIST service model, (2) RAs that use software stacks, (3) RAs that focus on functional capabilities, (4) High Technical abstraction, (5) RAs with user role as a focus, the sub-groups are expected to provide a summary of the following questions:

1.) Does the existing RAs follow the NIST's Cloud Computing essential characteristics, service models, and deployment models? 2.) Where does the model add insight to the RAs? 3.) What can be derived from the existing RAs to develop a "best-of-breed" Cloud Computing reference architecture based on NIST's Cloud Computing essential characteristics, service models, and deployment model?

Thank you and have a pleasant weekend.

Hung and Gregg
