Microsoft: Cloud need only be open surface, not open source
At Oscon 2011, Gianugo Rabellino, Senior Director for Open Source Communities at Microsoft, said as long as the APIs, protocols and standards for the cloud are open, that is, open surface, customers don't care about whether the underlying platform is open source or closed source. Microsoft also announced a new version of Azure SDK for PHP is now available and the company is announcing new tools to cloud enable open source applications for Azure.
