Microsoft 365 for enterprise deployment guide

The Microsoft 365 for enterprise deployment guide steps you through the correct and required configuration of Microsoft 365 for enterprise products and features.

To deploy Microsoft 365 for enterprise yourself, you can:

  • Deploy the foundation infrastructure for built-in security and integration for simplified management, which makes it easier to ensure your client software is updated with the latest productivity and security enhancements.

    The foundation infrastructure is organized as a series of numbered phases that build upon each other and towards an environment that supports Microsoft 365 for enterprise workloads.

    If you are a smaller or newer organization, follow the phases in order to methodically build out your infrastructure.

    However, you can deploy phases or the portions of phases of this infrastructure in any order as needed, one after the other or in parallel, to integrate with your current infrastructure, fit your IT plans and resources, and meet your business needs. For a simplified deployment for non-enterprises, click here.

    If you are an enterprise organization, view the phases as layers of IT infrastructure, rather than a defined path, and determine how to best work toward eventual adherence to the requirements of each layer across your organization.

  • Deploy key productivity workloads on top of your infrastructure. These unlock creativity and teamwork in your organization.

Here's the relationship between the foundation infrastructure and the workloads.

The relationship between the foundation infrastructure and the workloads

Workloads operate over the top of the foundation infrastructure. However, you do not have to have all of the foundation infrastructure phases built out to begin using workloads for productivity and collaboration.

"For the things we have to learn before we can do them, we learn by doing them." - Aristotle

If you're new to Microsoft 365 for enterprise or to a specific product or feature, one of the best ways to gain understanding is to build it out yourself and see it working.

We've made this easier with Test Lab Guides (TLGs), which step you through the configuration of infrastructure or a feature in a simplified but representative test environment using trial or paid subscriptions.

With TLGs, you can self-learn, demonstrate, customize, or build a proof of concept (PoC) of a complex configuration, workload, or end-to-end scenario.
