About Office 365 Dedicated Plans

 

Applies to: Office 365 Dedicated Plans

Topic Last Modified: 2012-12-04

The Office 365 dedicated plans and ITAR-support plans deliver cloud-based business services from Microsoft data center equipment that is dedicated to your company or organization and not shared with any other organization. With dedicated equipment, you are able to implement advanced service features and SharePoint Online customizations.

It is important to be familiar with the following Office 365 dedicated plans elements before starting your deployment project:

The following figure illustrates the service delivery architecture used for Office 365 dedicated plans.

Office 365 service offerings are a set of cloud-based business applications that are available together as part of the Office 365 suite or as standalone solutions. The dedicated plans make the following service offerings available:

  • Exchange Online
  • SharePoint Online
  • Lync Online

Dedicated plan deployment projects can also include the Microsoft Office Live Meeting web conferencing service and Microsoft Forefront Online Protection for Exchange message filtering solution. As shown in the previous service architecture figure, both are hosted at Microsoft data centers other than those that host and deliver Exchange Online, SharePoint Online, and Lync Online.

The Office 365 infrastructure components described below enable your organization to access and manage the Office 365 services that you use.

  • Data centers. Your organization is assigned primary and secondary Office 365 data centers from which your Exchange Online, Lync Online, and SharePoint Online services are delivered. These Microsoft data centers have redundant infrastructure that enable failover from one data center to another to support service continuity and disaster recovery scenarios.
  • Network connections. Network connectivity from your environment to the Microsoft data centers is required for users to access Office 365 services. The preferred connectivity option is for your organization to use connections that you own and operate, or via your designated provider.
  • Network security zones. The network architecture for Office 365 establishes three distinct security zones: the Customer Network, the Microsoft Managed Network, and the Microsoft Management Network. Each security zone is implemented as a virtual network.
  • Authentication architecture. The authentication architecture that enables you to access to Office 365 resources requires implementation of trusts between the Active Directory forest in your environment and the Office 365 forest managed by Microsoft.
  • Directory synchronization and provisioning. Dedicated deployments use the Microsoft Managed Solutions Service Provisioning Provider (MMSSPP) for directory synchronization and automated service provisioning between your Active Directory forest and the Microsoft hosting environment. MMSSPP reads directory provisioning information from your Active Directory and makes your identity data available in the Microsoft environment.
    noteNote:
    Exchange Online and Lync Online deployment both require use of MMSSPP. SharePoint Online requires MMSSPP only for integration of online presence with Lync Online, which is an optional Office 365 feature.

As described later in this guide, your organization and Microsoft each have defined responsibilities for deploying these components.

Establishing support services to help your Office 365 users quickly and efficiently resolve service-related issues is a key deployment project workstream. Microsoft trains your organization's Service Desk personnel to provide user support and how to escalate support issues to Microsoft.
