SharePoint 2013 Apps Advantages

SharePoint 2013 introduced a new feature called Apps. Apps are self-contained pieces of functionality that extends the capabilities of a SharePoint website.

Apps will be executed outside the SharePoint Server, and in the Client machine or in the Cloud. This makes Apps easier to install & clean up. Sandboxed Solutions are deprecated and new custom solutions should be provided through Apps.

1. Advantages to Users
2. Advantages to Administrators
3. Advantages to Developers
