As consumers, the web services and APIs offered by Google, eBay, Yahoo, and others have changed how the apps we use are created and re-used, and their role in making them more useful is clear. At work, the model for building mashups – and making them relevant to businesses – is now also emerging. With the shift to on demand and utility computing models, new mashups based on their consumer counterparts are changing the apps business people use, the way those apps are built, and the way companies profit from supplying them. Using demos, code examples, and case studies in this session, the technology and business models behind these new mashups will be presented.
