In SharePoint Server 2016, new hybrid features are available to enable hybrid solutions.

Hybrid sites

Hybrid sites feature

 It allow the users to have an integrated experience while using SharePoint Server and SharePoint Online sites:
  • Users can follow SharePoint Server and SharePoint Online sites, and see them consolidated in a single list.
  • Users have a single profile in Office 365, where all of their profile information is stored.

Hybrid OneDrive for Business

Hybrid sites features are used in concert with Hybrid OneDrive for Business (introduced in SharePoint Server 2013 with Service Pack 1 (SP1)):

  • Users can sync files with Office 365 and share them with others.
  • Users can access their files directly through Office 365 from any device.

Cloud hybrid search

Cloud hybrid search is a new hybrid search solution alternative. With cloud hybrid search:

  • The index of the crawled content, including on-premises content, to the search index in Office 365. You can set up the crawler in SharePoint Server 2016 to crawl the same content sources and use the same search connectors in Office SharePoint Server 2007, SharePoint Server 2010, and SharePoint Server 2013.
  • When users query your search index in Office 365, they get unified search results from both on-premises and Office 365 content.
