Organizations can integrate SharePoint Online and SharePoint Server on-premises to get some of the benefits of Microsoft hosting while keeping some SharePoint sites in-house. SharePoint Online, an Office 365 service, offers multitenant hosting of SharePoint installations in Microsoft data centers. A hybrid SharePoint system combining Microsoft-hosted and on-premises installations can be valuable during gradual migrations to SharePoint Online and in cases where some parts of the organization cannot migrate. However, a hybrid system will be more complex than a pure on-premises or online SharePoint system, which can diminish the benefits of a SharePoint Online migration.

Why Combine Online and On-Premises?

An organization might end up with both on-premises and Microsoft-hosted SharePoint installations for several reasons.

Gradual migration. The organization is migrating to SharePoint Online but needs to keep existing on-premises sites working during the migration. The existing sites might need redesign for compatibility with SharePoint Online, or the organization might just need time to move large volumes of data from its existing sites.
