Azure Management Groups (MG) provide a governance structure above subscriptions to manage policy, access control, and compliance. Management groups exist to group subscriptions so you can apply similar access control or policy to the resources within those subscriptions.
The UW has a legacy set of Management Groups which are being phased out over time to align with a fresh landing zone that aligns with UW cloud strategy and the Microsoft Cloud Adoption Framework (CAF). What you find here is based on the Azure design circa 2024 with some details about the new landing zone approach. As time permits, this page will be updated with new details to reflect the fresh approach and emergence of new managed Azure services. We've tried to note sections which are legacy that will be phased out.
