I’ve heard Microsoft say that the Windows Azure Platform is an open cloud platform. What makes it interoperable?
The Microsoft Windows platform supports a host of Microsoft and non-Microsoft languages, protocols and technologies. Our vision is to apply that same principle to Windows Azure. The Windows Azure platform supports popular standards and protocols including SOAP, REST, and XML. Developers can use their preferred programming frameworks including .NET, and PHP, now. The recent inclusion of Windows Azure support in the Zend framework is a case in point. We have partnered with Soyatec to create Eclipse tooling for PHP developers building Windows Azure applications.
