SharePoint Embedded is a new Microsoft offering for application developers. The big upside is that apps can take advantage of the Microsoft 365 ecosystem. Cost is the potential downside. Microsoft will charge using a pay-as-you-go model, but estimating the likely cost could be difficult until more experience about how apps use SharePoint Embedded emerges.
When Microsoft released the preview of the Loop app, we figured out that Loop uses a special form of SharePoint Online to store its workspaces and pages. Now we know that Loop uses Syntex Repository Services (SharePoint Embedded), a new offering that allows apps to create storage partitions within SharePoint Online and use those repositories to store the files needed by the app. It’s still early days for both the Loop app and Syntex Repository Services (in private preview) and many operational details need to be explored, but the new offering is an interesting choice for app developers when it comes to deciding where to store their data.
