Cloud computing has emerged from its back-end, client/server, roots, to create paradigms of its own. Processing on demand enables disruptive competitors to capitalise on success, without the huge investments they would once have needed, and standardised platforms are making Cloud development easier than ever before. Cloud developers have a broad range of skills, making categorisation by technology or target all but useless, so at VisionMobile we divide developers in to eight segments, based on what they want to achieve rather than the tools they use to achieve it. In this report we look in detail at the Cloud developer communities, seeing motivations map to tools and business models, providing an insight into what applications they are creating and how they are creating them.
