Azure Fundamentals (AZ-900) Study Guide

Chapter 8. The Azure Management Infrastructure

In this chapter, you’ll explore the Azure management infrastructure and learn how Azure organizes and governs cloud-based resources. You’ll examine the four hierarchical layers that form the foundation for structuring, securing, and managing Azure deployments:

• Resources

• Resource groups

• Subscriptions

• Management groups

Understanding this hierarchy is essential not just for real-world Azure administration but also for success on the AZ-900 Azure Fundamentals exam. As you progress, pay close attention to:

• How each layer relates to the others

• Which layers are used for billing, policy, governance, and access control

• Why resource organization matters for scalability, cost management, security, and compliance

By the end of this chapter, you’ll be able to clearly distinguish each management layer and understand how Azure’s governance model supports secure and efficient cloud operations, knowledge that is frequently tested on the AZ-900 exam.

What Is the Azure Management Infrastructure?

Azure’s management infrastructure is the organizational framework within Azure that governs how resources are structured, managed, and accessed. It establishes a hierarchy for organizing resources, applying policies, managing access, and controlling costs. This structure simplifies administration and ensures scalability, compliance, and security for projects and applications.

The management infrastructure resembles an onion (see Figure 8-1 ...
