Cloud Concepts
AZ-900 Domain 1 · 25–30% of the exam
What the cloud actually is, why businesses moved to it, the cloud models and service types, and the benefits every Azure conversation is built on.
Example lesson
What is Cloud Computing?
Cloud computing is the delivery of computing services (servers, storage, databases, networking, software and analytics) over the internet, on demand. You use what you need, when you need it, and pay for what you use, instead of buying and running your own hardware.

AZ-900 Domain 2 · 35–40% of the exam
How Azure is physically and logically organised, and the core compute, networking, storage, identity and security services you will meet in every project.
Example lesson
Azure Regions, Region Pairs and Sovereign Regions
An Azure region is a geographical area containing one or more datacenters connected by a low-latency network, such as West Europe or Southeast Asia. Many regions are grouped into region pairs in the same geography for disaster recovery. Sovereign regions, such as Azure Government and Azure operated by 21Vianet in China, are isolated instances of Azure for specific compliance or legal needs.
Try it yourself ❯Management & Governance
AZ-900 Domain 3 · 30–35% of the exam
Keeping Azure under control: cost, compliance, policy, the tools you deploy and manage with, and how you monitor what is running.
Example lesson
Factors That Affect Azure Costs
Azure costs depend on several factors: the resource type and its settings (size, tier, redundancy), consumption (how much and how long you use it), maintenance (cleaning up unused resources), geography (prices differ by region), network traffic (outbound data transfer), the subscription type and any Azure Marketplace purchases.
Try it yourself ❯Mock Exam
A timed, 40-question practice exam weighted like the real AZ-900. Mark questions for review, see your score by domain, and learn why every answer is right or wrong.
Original practice questions. Not real exam questions.
Example question
Which order shows the Azure management hierarchy from the HIGHEST level to the LOWEST?
- Subscriptions → management groups → resources → resource groups
- Resources → resource groups → subscriptions → management groups
- Management groups → subscriptions → resource groups → resources
- Resource groups → subscriptions → management groups → resources
Try it Yourself 🧪
Practise in a simulated Azure portal and Cloud Shell. Create VMs, storage and web apps, type real Azure CLI commands and watch the cost meter, with no Azure account needed.
Azure Cloud Shell (practice)
learner@Azure:~$ az vm deallocate -g rg-lab -n web01
💰 Cost: $8.76/mo → $4.38/mo
learner@Azure:~$ az group delete -n rg-prod
ERROR: (ScopeLocked) The scope 'rg-prod' cannot perform delete operation because it is locked…

Mock interview
Interviewer
What is the difference between scalability and elasticity?You
Scalability is the ability to add or remove resources. Elasticity is when that happens automatically, in real time, based on demand.Interviewer
Can you give me a real-world example?Made for every learner
A 10-year-old should understand the idea. A 20-year veteran should still learn something new.
School students
No cloud knowledge needed. Stories about libraries, games and pizza.
College & freshers
Cloud basics linked to real IT jobs, with a quiz after every lesson.
Developers
How Azure services fit into real apps, and when not to use them.
Experienced engineers
Architecture trade-offs, cost, security and scenario interviews.
