Microsoft 365 Enterprise foundation infrastructure
To fully realize the benefits of Microsoft 365 Enterprise, you’ll begin your deployment with its foundation infrastructure.
Foundation infrastructure for deploying Microsoft 365 Enterprise
The foundation infrastructure is the groundwork upon which you can deploy productivity workloads (such as Microsoft Teams and Exchange Online in Office 365) and scenarios (such as migrating to Microsoft 365 and automating client updates). It provides intelligent security and integration that simplifies ongoing management, which ensures that your client software is updated with the latest productivity and security enhancements.
You'll use the following phases to plan for and deploy the foundation infrastructure of Microsoft 365 Enterprise in your organization:
|Phase 1: Networking|
|Phase 2: Identity|
|Phase 3: Windows 10 Enterprise|
|Phase 4: Office 365 ProPlus|
|Phase 5: Mobile device management|
|Phase 6: Information protection|
Before you can exit each phase, you must examine its exit criteria, which is a set of required conditions that you must meet and optional conditions to consider. Exit criteria for each phase ensures that your on-premises and cloud infrastructure and resulting end-to-end configuration meet the requirements for a Microsoft 365 Enterprise deployment.
