Hybrid SharePoint & Office 365
Hybrid SharePoint environments combine on-premises Microsoft SharePoint Server with Office 365 — Microsoft SharePoint Online. The goal of any hybridization, or combining of two related but dissimilar entities, is to leverage the strengths of both parts, while minimizing the components’ weaknesses. Hybrid environments enable organizations to realize a higher degree of flexibility than forcing a choice between either an on-premises or cloud model. Organizations can start to achieve the benefits associated with the use of cloud computing coupled with the customization, flexibility, and tight data governance of an on-premises system; while delivering a consistent experience to users.
Hybrid environments can be helpful when it is not possible for an organization to migrate to the cloud immediately or in full due to business, technical or other reasons. Common scenarios of where hybrid environments can be useful include ....
Rapid provisioning of new workloads on Office 365 while maintaining existing on-premises workloads.
Organizations wishing to migrate workloads from an existing on-premises environment to the cloud over time in a phased approach.
Organizations wanting to supplement their cloud environment with additional features or customizations which are currently only possible on-premises.
Compliance or data sovereignty reasons which might stipulate certain data be hosted in a particular location.
Office 365 offers many features which can aid an organization in deploying a robust hybrid environment. In SharePoint 2010/13 the two SharePoint installations that make up a hybrid environment – on-premises and Office 365 – are largely separate. A thoughtful hybrid design helps bridge the gap between these two distinct deployment environments.
Organizations can choose how tightly they want to blend their on-premises and cloud environments depending on their appetite for configuring or adding customizations and their long term-plans.
In a hybrid SharePoint Server 2013/Office 365 environment, you can configure single sign-on (SSO) to federate your on-premises Active Directory Domain Services (AD DS) domain with your Office 365 Enterprise tenant, just like you could in SharePoint Server 2010. SharePoint Server 2013 also includes native support for OAuth 2.0 to enable server-to-server trust relationships between SharePoint Server and SharePoint Online. A hybrid SharePoint environment uses this server-to-server trust relationship at the service level to deliver cross-boundary functionality and content on behalf of authenticated users.
