This article unpacks the foundational topics that will prepare you for AZ-900, from the core cloud concepts to the key Azure services. If you’re ready to get down to the brass tacks of cloud computing, let’s jump right in.

What Is Cloud Computing?

Cloud computing, at its essence, is about delivering computing resources over the internet instead of relying on local servers or personal devices. Think of it like renting a powerful computer in the sky, where you access everything remotely.

With cloud services, you don’t have to worry about buying, maintaining, or upgrading physical hardware. Instead, providers like Microsoft Azure manage that infrastructure, allowing you to focus on your applications, data, or development tasks. This shift leads to several advantages:

Scalability: Instantly scale resources up or down based on demand.
Cost Efficiency: Pay only for what you use, avoiding large upfront investments.
Accessibility: Access resources anywhere with internet connectivity.
Speed: Deploy and manage applications quickly without hardware delays.

Understanding these benefits lays the groundwork for appreciating why cloud adoption is skyrocketing across industries.

Different Cloud Deployment Models

Not every cloud setup looks the same. Azure operates primarily as a public cloud provider, but it’s essential to know the three main deployment models you’ll encounter:

Public Cloud

Public clouds are owned and operated by third-party providers like Microsoft. Resources are shared across multiple customers, making it a cost-effective and flexible option. Azure’s global data centers power this model, offering massive infrastructure with economies of scale.

Private Cloud

Private clouds are exclusive to a single organization, either hosted on-premises or by a third party. This model provides more control and enhanced security but usually comes at a higher cost and complexity. Businesses with strict compliance requirements often prefer private clouds.

Hybrid Cloud

Hybrid clouds combine public and private clouds, allowing data and applications to move between environments as needed. This model provides flexibility, letting organizations keep sensitive data on-premises while leveraging the public cloud for scalability.

Knowing these models helps you understand how businesses architect their cloud solutions and why different approaches fit different scenarios.

Cloud Service Models: IaaS, PaaS, and SaaS

Next up, you need to grasp how cloud services are categorized based on what the provider manages versus what the user controls. Azure offers three primary service models:

Infrastructure as a Service (IaaS)

IaaS provides raw computing resources like virtual machines, storage, and networking. You’re responsible for managing the operating system, applications, and data. Azure Virtual Machines are classic IaaS examples. This model is great for users who want control over their environment but don’t want to invest in physical hardware.

Platform as a Service (PaaS)

With PaaS, you get a ready-made platform to develop, run, and manage applications without worrying about the underlying infrastructure. Azure App Services let you deploy web apps and APIs quickly, handling OS patches, scaling, and maintenance automatically. PaaS accelerates development cycles by offloading operational tasks.

Software as a Service (SaaS)

SaaS delivers complete software applications over the internet, managed entirely by the provider. Users simply access the software via a browser or app. Microsoft 365 (formerly Office 365) is a prime example. SaaS removes the need for installation or management, making it easy to consume and maintain software.

These models show the spectrum of cloud responsibility, from full control with IaaS to zero infrastructure management with SaaS.

Core Azure Services: The Backbone of the Platform

Azure Security Features: Shielding Your Cloud Environment

Security isn’t just a checkbox; it’s woven into every layer of Azure’s architecture. The cloud brings unique risks, so Microsoft builds in comprehensive security features to protect your data, applications, and identities.

Network Security

Azure Firewall is a managed service that protects your virtual networks from malicious traffic. It acts as a central control point, filtering both inbound and outbound traffic.

Network Security Groups (NSGs) provide granular control by defining rules at the subnet or VM level, controlling what kind of network traffic is allowed or denied.

Azure DDoS Protection guards against Distributed Denial of Service attacks, which flood your resources with bogus traffic to cause downtime. It automatically detects and mitigates such attacks to keep your apps running smoothly.

Identity and Access Management

Azure Active Directory (Azure AD) is the backbone of identity management in Azure. It enables single sign-on (SSO), multi-factor authentication (MFA), and conditional access policies that enforce strict login requirements based on user location or device compliance.

RBAC (Role-Based Access Control) lets you assign precise permissions to users, minimizing risk by ensuring people only access what they need.

Data Security

Data encryption is standard in Azure, both at rest and in transit. Azure Storage Service Encryption automatically encrypts data before it’s written to disk.

Azure Key Vault provides a secure way to manage encryption keys, secrets, and certificates, preventing unauthorized access.

Security Monitoring and Management

Azure Security Center offers a unified view of your security posture, providing recommendations and threat detection. It uses AI to identify vulnerabilities and potential attacks, helping you respond quickly.

Microsoft Defender for Cloud integrates with Security Center to protect workloads across hybrid environments, detecting suspicious activities and automatically mitigating threats.

Governance and Compliance: Keeping Control in a Complex Cloud World

Managing a sprawling Azure environment can get wild without proper governance. Azure offers tools to enforce organizational policies, maintain compliance, and control costs.

Azure Policy

Azure Policy lets you define rules for resource properties during deployment or runtime. For example, you can require all resources to have tags for department tracking or restrict deployment to specific regions.

Policies can be assigned at different scopes, such as subscriptions or resource groups, and non-compliant resources can be flagged or automatically remediated.

Resource Locks

Resource locks prevent accidental deletion or modification of critical resources. You can apply “ReadOnly” locks, allowing viewing but no changes, or “Delete” locks to block deletion.

This adds a layer of safety for production environments where mistakes can be costly.

Azure Blueprints

Blueprints let you package environment configurations, policies, and role assignments into reusable templates. This helps create standardized, compliant environments quickly, perfect for large organizations managing multiple subscriptions.

Cost Management and Billing

Understanding and controlling cloud costs is vital. Azure Cost Management tools provide detailed insights into spending, budgets, and forecasts. You can set alerts when costs exceed thresholds and analyze spending by resource, department, or project.

Why Knowing Azure Management Tools and Security Is Critical for AZ-900

Mastering Identity and Access Management in Azure

When it comes to cloud security, identity isn’t just a checkbox — it’s the first line of defense. Azure’s identity services form the backbone for securing who can access what, when, and how.

Azure Active Directory: The Identity Gatekeeper

Azure Active Directory (Azure AD) is Microsoft’s cloud-based identity and access management service. It’s not just about signing in — it’s about managing identities at scale across apps, devices, and services.

Azure AD supports:

Single Sign-On (SSO): One login for multiple apps, making life easier for users and admins.
Multi-Factor Authentication (MFA): Adds a second layer of security beyond passwords, often a phone notification or biometric check.
Conditional Access: Dynamic policies that grant or deny access based on user location, device state, or risk profile.
Self-Service Password Reset: Saves admins time and lets users regain access without tickets.

Azure AD integrates tightly with Microsoft 365, Azure services, and thousands of SaaS apps, making it the heartbeat of identity in the Microsoft ecosystem.

Role-Based Access Control (RBAC): Fine-Tuning Permissions

RBAC is Azure’s way of enforcing the principle of least privilege. Instead of giving broad access, RBAC assigns specific roles with precise permissions to users, groups, or service principals.

For example, you might give a developer permission to manage app services but block access to financial records or critical VMs. RBAC roles include Owner, Contributor, and Reader, but you can also create custom roles tailored to your needs.

Using RBAC means fewer mistakes, better security, and clearer accountability.

Azure Governance: Keeping Cloud Chaos in Check

Cloud environments can grow fast — and without guardrails, they turn into a wild mess. Azure’s governance tools help organizations control costs, enforce standards, and stay compliant.

Azure Policy: Rules That Stick

Azure Policy lets you create rules to enforce organizational standards automatically. Whether it’s requiring tags on resources, restricting VM sizes, or forcing encryption, policies keep deployments in check.

You can apply policies at different scopes — management groups, subscriptions, resource groups — ensuring consistency no matter how big your environment gets.

Non-compliant resources get flagged or even remediated automatically. It’s like having a watchdog that never sleeps.

Resource Locks: Lock It Down

Resource locks add an extra layer of protection against accidental changes or deletions. You can apply:

ReadOnly lock: Prevents changes but allows viewing.
Delete lock: Prevents deletion but allows changes.

Applying locks on critical resources like production VMs or databases safeguards your environment from human error or rogue scripts.

Azure Blueprints: Repeatable, Compliant Environments

Blueprints are templates combining infrastructure as code, policies, and RBAC into reusable packages. They let you spin up compliant, secure, and standardized environments in minutes. This is a huge time saver for enterprises needing consistent setups across multiple teams or projects.

Privacy and Compliance in Azure: Staying Legit in the Cloud

Handling data responsibly is non-negotiable. Azure takes privacy and compliance seriously, with built-in features to help organizations meet strict legal and industry requirements.

Compliance Certifications and Standards

Azure meets dozens of global standards like:

GDPR (General Data Protection Regulation)
HIPAA (Health Insurance Portability and Accountability Act)
ISO 27001 (Information Security Management)
SOC 1, SOC 2, SOC 3 (Service Organization Controls)
FedRAMP (Federal Risk and Authorization Management Program)

These certifications mean Azure undergoes rigorous audits and follows best practices, helping customers stay compliant without reinventing the wheel.

Data Residency and Sovereignty

Some industries or countries require data to stay within specific geographic boundaries. Azure lets you choose regions to deploy resources, helping comply with data residency laws.

Azure also supports encryption of data at rest and in transit, giving you control over how data is protected physically and digitally.

Privacy Controls and Transparency

Azure provides tools for monitoring data access and managing consent. Azure’s Trust Center offers transparency on data handling, ensuring customers understand how Microsoft protects their data.

Managing Costs and Understanding Service Level Agreements (SLAs)

Cloud bills can spiral out of control if you’re not careful. Azure offers several ways to keep costs in check and guarantees availability with SLAs.

Azure Cost Management: Tracking and Optimizing Spend

Azure Cost Management helps you track usage and spending across subscriptions. You can set budgets, create alerts, and analyze costs by resource or department.

Regularly reviewing cost reports helps prevent surprise bills and identify inefficiencies — like unused VMs or over-provisioned storage.

Pricing Models to Know

Azure uses a pay-as-you-go model, billing you for what you consume. This includes compute hours, storage, bandwidth, and more.

Some services offer reserved instances or savings plans that reduce costs if you commit to usage over time.

Understanding SLAs: What Microsoft Promises

An SLA defines the guaranteed uptime or availability of a service, usually expressed as a percentage (e.g., 99.9%).

Azure’s SLAs vary by service, but Microsoft compensates customers if it fails to meet these guarantees.

Knowing SLAs helps you design solutions with the right availability and redundancy, balancing cost and reliability.

The Bigger Picture: Why These Topics Matter for AZ-900

The AZ-900 exam tests more than just definitions. It wants you to grasp how identity, governance, privacy, and cost control fit into real-world cloud operations.

Understanding these areas shows you how organizations protect data, enforce policies, control budgets, and build trust with customers — all critical in today’s cloud-driven business.

Mastering these topics sets you up to move beyond fundamentals and dive into specialized roles like security engineer, cloud architect, or compliance analyst.

Grasping Azure’s identity management, governance frameworks, privacy safeguards, and cost controls is like holding the steering wheel to your cloud journey.

These pillars ensure your cloud environment is secure, compliant, and efficient, ready for whatever challenges lie ahead.

Azure Pricing Models: Navigating the Cost Maze

Cloud costs can feel like a maze if you don’t know where you’re headed. Azure’s pricing structure is designed to be flexible but understanding it is crucial to avoid nasty surprises.

Pay-As-You-Go: The Default Mode

Most Azure services charge on a pay-as-you-go basis. This means you pay only for what you consume—compute hours, storage, data transfer, etc.—with no upfront commitment. It’s great for experimentation or projects with variable workloads.

However, it’s easy to rack up costs if resources aren’t managed properly, like forgetting to shut down VMs or leaving services running idle.

Reserved Instances and Savings Plans

For predictable workloads, Azure offers reserved instances, where you commit to using certain resources for one or three years at a discounted rate. This can save up to 72% compared to pay-as-you-go prices.

Savings Plans work similarly by offering discounts for committed usage across a range of compute services, giving you flexibility without breaking the bank.

Spot Instances: Bargain Compute Power

Spot instances let you use unused Azure capacity at a fraction of the price. The catch? These VMs can be evicted when Azure needs the capacity back, so they’re best for fault-tolerant or batch workloads.

Free and Trial Tiers

Azure provides a free tier with limited usage of services like Azure Functions, App Service, and Storage Accounts, plus a 12-month free trial with credits to explore paid services.

These options are perfect for newcomers wanting hands-on experience without immediate costs.

Understanding Azure Service Level Agreements (SLAs)

SLAs are the promises Microsoft makes about how reliable its services will be. They’re vital to understand for designing robust systems and setting expectations.

What SLAs Cover

Azure SLAs specify uptime percentages, usually expressed as a percentage like 99.9% (the famous “three nines”). This translates to allowed downtime per month or year.

For example, a 99.9% SLA means up to 43.8 minutes of downtime per month.

Different SLAs for Different Services

Each Azure service has its own SLA. Some core services like Azure Virtual Machines offer 99.9%, while others might guarantee higher or lower availability.

SLAs often assume you deploy resources in certain ways, like using availability zones or sets. If you don’t follow best practices, your real uptime might be lower.

What Happens if SLAs Aren’t Met

Microsoft offers service credits as compensation if SLAs aren’t met, reducing your bill based on the downtime experienced. This is rarely a full refund but helps offset the impact.

Designing for Availability

Knowing SLAs helps you architect your applications to meet business needs. Combining multiple instances, geographic redundancy, and failover strategies improves availability beyond single SLAs.
