3. Adds some specific functionality to a site
Apps should be safe
Apps can be obtained from the app store (“SharePoint
Store”)

4. The most important guidance we can give you is
to develop an app for SharePoint rather than a
classic solution whenever you can.

5. End-user familiarity
Game-changer for Office 365
Reduce upgrade blockers

6. Are we going to allow apps?
Are we going to allow ANY app from the SharePoint
Store to be installed?
Will our own customisations be developed as apps?

Cloud app

9. Secure Sockets Layer (SSL) is a requirement for web
applications that are deployed in scenarios that support
server-to-server authentication and app authentication.
