Microsoft recently did its best to promote its Software Plus Services
strategy at its S+S:

The software giant’s chief executive officer, Steve Ballmer, addressed
executives, Gold partners and IT managers and

professionals at its London partner summit about how Microsoft is
responding to changes in the IT market.

At Microsoft’s World Partner Conference (WPC) in July, Microsoft
signalled a shift in its Software as a Service (SaaS)

strategy, announcing that partners can net six per cent annual
recurring revenue.
