People are getting more and more connected and moving away from computers to using more mobile devices than ever before. Tablets, phones, slates are becoming the new computers. All these devices and applications also need data, synchronization, security and much more. The broad reach, the number of devices and apps and the big amount of different platforms existing today, are pushing the needs for scalable and high available solutions running on a solid cloud platform, like Windows Azure. One of the killer features of Windows Azure is WAMS, the Windows Azure Mobile Services. A Solid platform to connect cross platform devices and to open up a big set of features needed to build mobile applications. In this session we will give you an introduction to WAMS, show you its true power and demonstrate how it can be used on multiple platforms to have one common way of connectivity. Managing and opening up your data to mobile users, while keeping the flexibility of validation and queries. Securing your applications by enabling authentication and authorization and by allowing the user to do single sign on or to use his favorite identity provider like Live, Facebook or Twitter. Enabling standard communication means like email and SMS, directly from your own application. And last but not least, enriching applications using push notifications, to send information from server to client and to notify users about new content.
