Cloud computing is going to be the focal point at Microsoft’s Professional Developers Conference (PDC), according to eWeek. The company will share its “services aspirations” and there is every possibility it might shed light on its so-called “Cloud OS”. But Windows 7 is expected to assume more importance than anything else at PDC.

Though cloud computing and Windows 7 are most certainly going to attract all the attention at PDC, the company is expected to shed more light on its Oslo modeling platform and Visual Studio 2010 as well. "There will be lots of talk of interoperability and how developers not on the platform can work with Microsoft technology," said Tim O'Brien, senior director of platform strategy at Microsoft.
