SharePoint Hybrid Planning and Deployment

• Sensitive content and server-side customizations that cannot move to SharePoint Online can stay on-premises in a hybrid architecture.
• Most organizations will move to hybrid SharePoint only if a full migration to SharePoint Online is too challenging or impossible.

Hybrid deployment of SharePoint involves enabling trusted communications between the Microsoft-hosted SharePoint Online service and an organization’s on-premises SharePoint Server installation, and then integrating functionality between the two. Organizations can choose which features and functions are handled by SharePoint Online, such as integrated search, user profiles, and site creation. However, hybrid deployments are likely to increase complexity and licensing costs, so most organizations should consider them in situations where some necessary features are unavailable in SharePoint Online, or in other cases when a full transition to the hosted service is not immediately possible.
