Yunfei/Wang/Meng,

My interest was not limited to virtual machines (which require some amount
of choreography on either side of the actual move) but rather files,
databases, code, documents - basically anything that you might want to move
from A to B (where you are not necessarily A or B).

Another area of potential interest is a lightweight "profile" of HTTP for
constrained devices, whereby one does not have to implement a full-blown
HTTP client & server pair simply to query an electricity meter. Some of
these issues were already discussed earlier this week[1]. The same could be
said for application of [vanilla] HTTP to files, databases, etc. (e.g. the
relevant subset of CDMI).

We're also missing a way of describing containers (e.g. hypervisors,
platforms, etc.) and workloads (e.g. applications, virtual machines).
CloudAudit provides a technical solution to the former (but it's out of
scope) and Cisco's James Urquhart has been working on a descriptor format
for the latter[2]. Both of these areas seem appropriate for IETF
involvement, and indeed CloudAudit could be worked into a generic catalog
service (e.g. the legal name of the provider, its location, logo, services,
SLAs, etc.).

I think the best next step would be for to work torwards formalising the
"clouds" effort somewhat, which will necessarily involve enumerating the
opportunities for standards development and prioritising them. IETF-78 would
presumably be a good forum for this activity (assuming it can't be done more
inclusively on this mailing list).
