Hello, Hoodies!

Most AZ-900 study materials are bloated, overwhelming, or written like corporate documentation.
You don’t need that — and the exam doesn’t test that.

What works best (and what dozens of students have already used to pass in the last few weeks) is something much simpler:

👉 A tight set of four synthesized lecture notes — one for each AZ-900 module — distilled from the actual Speedrun curriculum.

These aren’t 200-page eBooks.
They’re clean, structured, exam-ready summaries of exactly what you need to know.
Nothing extra. Nothing hidden. Nothing academic.
Just the stuff that makes Azure finally “click.”

This is straight from our AZ900 Speedrun in our Skool Community that has already helped several get certified, including 2 in the past 2 days!

Below is an overview of what each lecture note covers.


1️⃣ Cloud Fundamentals & Core Concepts

This guide breaks down the real foundations of cloud computing in a way Azure’s documentation never does. It’s the fastest way to make sense of the exam’s early conceptual questions.

Inside you’ll find:

  • Cloud benefits: high availability, fault tolerance, scalability, elasticity, agility

  • NIST cloud characteristics (on-demand, broad access, pooling, elasticity, measured service)

  • CapEx vs OpEx — the real mental model the exam tests

  • Shared responsibility model

  • Deployment models (Public, Private, Hybrid)

  • IaaS vs PaaS vs SaaS vs Serverless — with the exact comparisons the exam uses

This is the “vocabulary of the cloud” section — once you get this, Azure stops being confusing.


2️⃣ Azure Architecture & Core Services

This is the essential Azure overview — the part that teaches you how Azure actually fits together.

Contents include:

  • Regions, Region Pairs, Sovereign Clouds

  • Availability Zones and redundancy SLAs

  • The Azure hierarchy (Management Groups → Subscriptions → Resource Groups → Resources)

  • Compute models: VMs, App Service, Functions

  • Networking essentials: VNets, NSGs (preview), VPN Gateway vs ExpressRoute

  • Storage fundamentals: LRS vs ZRS vs GRS vs GZRS

  • Blob/File/Queue/Table storage — with exam-relevant scenarios

  • Database options: Azure SQL, Cosmos DB, PostgreSQL, MySQL

This is where people normally get lost with Azure’s terminology — the synthesized notes eliminate all that noise.


3️⃣ Azure Security, Identity, and Access Management

Identity is the #1 most important topic on the exam — and this guide makes it simple.

You’ll learn:

  • Microsoft Entra ID (Azure AD) fundamentals

  • Authentication vs Authorization (AuthN vs AuthZ)

  • RBAC roles, scopes, and role assignments

  • Zero Trust principles

  • Microsoft Defender for Cloud vs Microsoft Sentinel

  • Network security (NSGs, Azure Firewall, WAF)

  • Data encryption (transit, at rest, CMK)

  • Defense-in-depth layered model

  • Governance & compliance fundamentals

This guide clarifies nearly every “tricky wording” Microsoft likes to use in security questions.


4️⃣ Governance, Monitoring & Cost Management

This is where AZ-900 ties everything together — governance, policies, monitoring, automation, and cost.

Inside:

  • Azure Policy (definitions, initiatives, assignments, effects)

  • Management Groups for large org structures

  • Resource tags, locks, blueprints

  • Azure Monitor, Log Analytics, Application Insights

  • Cost Analysis, Budgets, and Azure Advisor

  • ARM templates, Bicep, CLI, PowerShell, Cloud Shell

  • Purview and enterprise data governance

This is the lecture note that turns Azure from a bunch of services into a well-governed system — exactly how Microsoft wants exam-takers to think.


🎯 Final Thought

You don’t need endless videos.
You don’t need massive PDFs.
You definitely don’t need to memorize every Azure service under the sun.

You need clarity.
You need structure.
You need the right information; distilled and organized.
