Why did we introduce SharePoint App pattern?

In this video, we will have high level look on the SP App or CAM (Cloud App Model) patterns. There won’t be any demos, since we’ll rather concentrate on why the SP App pattern was introduced in SharePoint 2013 and where it is suitable model. Covered topics also includes general notes or conclusions on using SharePoint as the development platform in general. Content is more on the architectural design decision level and does not include any code examples.
