Think SharePoint 2013 as a Portal Platform, which help you understand the new paradigm shift, which helps lots of developer to do program using C#, Python, Ruby, Java, PHP, NodeJS. The SharePoint 2013 App model is based on web standards: HTML 5, CSS, JS, OAuth 2.0 and OData. Today SharePoint enable most of the SharePoint API functions remote accessible the remote interface is much easier to maintain and more secure. This also concept also open door for SharePoint Developer create Facebook kind of applications for SharePoint and Office.

  • Timer jobs are not possible within an app
  • Deep changes to the user site are not possible with an app
  • Cannot have any server-side SharePoint code

Very nice article...SharePoint 2013 apps model looks quite promising ..however, limitation on timer job & server OM at least for me somewhat a bit drastic ...I still didn't have "hands on" in terms of SharePoint apps yet ...

Nice article. I have been enlightening a couple of my team mates on the App Model and the whole mindset shift required to understand them.

And they were giving me the "I don't know what you are talking" looks. It will take time to seep in.
