Add-ins Transformation

Farm solutions are not available in SharePoint Online. To build customizations in a hybrid scenario  or cloud only approach customers must use the SharePoint add-in model.
There are many other benefits to using the add-in model over farm solutions:

  • They are the focus of Office engineering team moving forward
  • Greatly reduce the risk of impacting the performance of SharePoint Server farms
  • Improve the stability and reduce operational cost of the SharePoint Server farm
  • Can scale out the application without scaling out the entire SharePoint Server farm
  • Does not require dedicated farms for customizations due to application isolation
  • Does not require downtime for SharePoint to deploy updates
  • More flexible deployment patterns to improve agility and reduce time to market for the business and end users
  • Allows customers/SI’s to leverage standard Web Development skills over much harder to obtain SharePoint Development skills that have been traditionally employed
  • Will run in both SharePoint Server and SharePoint Online

During this process there were many valuable assets created which are now shared publicly on

Case Studies


The ready-to-use Valo solution brings popular intranet features to Microsoft Office 365. Blue Meteorite, the Finland-based company behind Valo, decided to move the solution to a cloud add-in model. As a result, the company has gained new customers and is better positioned to expand from the Nordic market to a broader, worldwide market.
