Its not just Sonian Amazon’s interested in; Amazon has also made several other investments in the cloud services arena and beyond, while also developing out its own Web Services, making the cloud more scalable for small businesses and app developers. An investment where the cloud meets location and marketing is LivingSocial, a local leader in providing deals and shopping experiences. To attract more developers to its camp, Amazon is also currently working on an AppStore, based on Android’s OS.
