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).
