A group of prominent cloud vendors has banded together behind an open source project that promises to make application services available across clouds. Zend Technologies, the supplier of the PHP scripting language, launched the Simple API project Tuesday, and IBM and Microsoft were among the first vendors to sign on.

The Simple API is intended to provide a common API set from which developers may call application services, regardless of which cloud they reside in.
