Using the new tools included in the Windows Phone 8.1 SDK, it is easier than ever to create apps that share most of their code. Code can be shared using the new shared app template in Visual Studio, as well as by creating Portable Class Libraries. This session walks through the development of a shared app, showing you where code can be shared and where it still makes sense to implement platform-specific features.
When designing cloud applications, you should take into account the fact that a failure or malfunction of any component of the system is possible. This template is called Designing for Failure. This design approach helps minimize the negative consequences of failure of any component of the internal or external system. Sometimes, it is not so simple to use the Designing for Failure template, but the Azure platform greatly facilitates this task due to the fact that some of the functions are implemented by cloud services—Azure Web Sites, Traffic Manager, CDN, RA—Geo Redundant Storage. During this session, we shall talk about how to use the functionality provided by Azure to ensure the accessibility of a website, even in the event of failure of one of the regions of the platform.
