Creating a SharePoint hybrid environment is about leveraging both SharePoint Server on premises and Office 365 SharePoint Online to achieve your business goals.
A hybrid environment enables enterprise users to be connected from almost anywhere to the resources and content they need.
A hybrid solution can help your company get started in the cloud, taking a first step to explore the cloud functionality at own your own pace. With the Hybrid functionality in SharePoint Server and Office 365, extend your on-premises investment to the cloud by integrating services and moving workloads to the environment that meets your organizational strategy.
File sync and share (Hybrid OneDrive)
Storing business files in OneDrive for Business makes it easy for users to share and collaborate on documents. With Office 365, you can also reduce your on-premises storage costs by moving your users' files to the cloud.
With Hybrid OneDrive for Business, users are "redirected" from SharePoint Server to OneDrive for Business in Office 365.
Using online services lets you focus on your business, without worrying about managing server infrastructure or how employees will access the information they need.
Hybrid Search & Site Features
With Hybrid Search, you can search for files and documents across SharePoint Server and SharePoint Online, giving you easy access to the files that you need.
Implementing a SharePoint hybrid infrastructure lets users search from both systems and access content from each. You can also make working with both environments more seamless by using hybrid profiles, and the extensible hybrid app launcher.
Business to Business Extranet (Partner facing extranet sites)
An extranet is a site that organizations create to let external users have access to relevant content and to collaborate with them. Using Office 365, you can create partner facing extranet sites that let partners securely do business with your organization.
With SharePoint Hybrid extranet, partners connect directly to a members-only site in Office 365, without access to the corporate on-premises environment or any other Office 365 site.
Extensible Hybrid App Launcher
With App Launcher, Admins can create a modern productivity experience for their users. The Extensible Hybrid App Launcher helps users to have a more seamless experience when navigating between your on-premises SharePoint Server and Office 365. Once you enable this feature, Office 365 Delve and Video apps, along with your custom Office 365 tiles, appear in your SharePoint Server app launcher.
SharePoint Hybrid Auditing (Preview)
SharePoint Hybrid Auditing (Preview) is a new feature in SharePoint Server 2016.
With SharePoint Hybrid Auditing, SharePoint administrators now have visibility to users' file access activities in their SharePoint 2016 on-premises farms or in their SharePoint Online sites.
SharePoint Hybrid Taxonomy and Hybrid Content Types
SharePoint hybrid taxonomy allows SharePoint administrators to create shared taxonomies (managed metadata) between their on-premises SharePoint Server and SharePoint Online. With SharePoint hybrid taxonomy, changes and updates to your SharePoint Online taxonomy are replicated in your SharePoint Online sites as well as your SharePoint Server 2016 sites.
With hybrid content types, you can have a shared set of content types between SharePoint Server and SharePoint Online which are mastered in SharePoint Online.
