The document discusses the new app model for SharePoint introduced with Office 365 and the cloud. It provides advantages of the app model for administrators, users, and developers. Specifically, apps run without custom code on SharePoint servers, induce less server load than sandboxed solutions, and are configurable by administrators. For users, apps are available through a catalogue and provide easy discovery, installation, and future upgrade support. Developers can use familiar web skills and standards to create apps, and Microsoft provides Visual Studio support. Examples of SharePoint hosted and store apps are provided from the company Raona.
