Overview of the AZ-900 Exam
The AZ-900 certification validates foundational knowledge of cloud concepts and Microsoft Azure services. The exam is structured across three primary domains:
Cloud concepts (25–30 percent)
Azure architecture and services (35–40 percent)
Azure management and governance (30–35 percent)
Understanding how these domains connect is essential for both exam success and practical cloud awareness
Cloud Concepts Explained
Cloud computing refers to the delivery of computing services such as servers, storage, databases, networking, software, and analytics over the internet. This model enables faster innovation, flexible resource allocation, and cost efficiency.
Key benefits of cloud services include high availability, scalability, predictable performance, built-in security, governance controls, and simplified management through automation and centralized administration.
The guide introduces the three core cloud service models:
Infrastructure as a Service (IaaS) for virtualized compute and networking
Platform as a Service (PaaS) for application development and deployment
Software as a Service (SaaS) for fully managed applications delivered via subscription
Cloud deployment models including public, private, and hybrid cloud are also explained to highlight trade-offs between control, security, and scalability.
Azure Architecture and Core Services
Azure’s global architecture is built on data centers organized into regions and availability zones, ensuring resilience, fault tolerance, and high availability.
The study notes cover essential Azure service categories:
Compute services such as Azure Virtual Machines, Azure App Services, and Azure Kubernetes Service support scalable application workloads.
Networking services including Virtual Networks, Load Balancers, and Application Gateways enable secure and efficient communication between resources.
Storage services such as Azure Blob Storage, File Storage, and Disk Storage provide flexible options for structured and unstructured data.
Database services including Azure SQL Database, Azure Cosmos DB, and managed MySQL and PostgreSQL offerings support a wide range of data workloads.
Azure Management, Monitoring, and Governance
Managing cloud environments effectively is as important as deploying them. Azure provides built-in tools to control cost, enforce standards, and monitor system health.
Cost Management tools help organizations estimate, track, and optimize cloud spending.
Governance and compliance capabilities such as Azure Policy and Azure Blueprints allow teams to enforce organizational standards and regulatory requirements.
Monitoring tools including Azure Monitor and Azure Service Health provide visibility into application performance, infrastructure health, and service availability. Azure Monitor’s architecture integrates data collection, storage, analysis, and visualization to support informed operational decisions.
Exam Preparation Resources
The guide highlights official Microsoft resources to support exam readiness:
Free practice assessments to identify knowledge gaps
The exam sandbox to experience the test interface
Microsoft Learn paths offering interactive modules and hands-on learning
Using these resources alongside structured study notes significantly improves confidence and exam performance.
Conclusion
Azure Fundamentals Study Notes provide a clear and practical pathway for understanding cloud concepts and Microsoft Azure services. By mastering these foundations, learners gain both certification readiness and essential cloud literacy applicable across modern IT and cybersecurity roles.
Achieving the AZ-900 certification demonstrates a solid grasp of cloud fundamentals and serves as a strong starting point for advanced Azure and security certifications.
