Bob/Nathaniel,

At this stage we have proven that there is significant interest in cloud
computing within the IETF community - the bar bof was full and overflowing
into the corridor and many tactical opportunities for work have been
identified with a lot of work already having been done (e.g. Bhumip's SDO
survey, my CloudAudit and HTTP enhancement drafts, etc.). We now need to
find a sensible way forward and my preferred option is to get some runs on
the board by completing specific tasks, some of which have already been
identified. The metric ought to be a> participants willing to do the work
and b> implementors willing to implement it.

I specifically don't think that a top down approach is appropriate here
(e.g. developing a reference framework, prioritising areas for
standardisation, etc.) - groups trying (and failing) at this are a dime a
dozen. I'd also prefer to constrain the group by depth rather than scope -
cloud, like internet, is a very broad area and most topics already overlap
with existing areas/working groups (e.g. CloudLog building on syslog).
There's no point trying to create a mini-IETF within IETF.

As for the two identified below, I think it's telling that the TM Forum felt
the need to appoint a "*Vice President and Head of Digital Media,
Advertising & Cloud Computing Programs*" and consider OVF to be the single
biggest threat to portability in that it could very easily become the Word
DOC format of the cloud. In any case getting caught up in what others are
doing is not going to help us get anything done ourselves.
