Introduction to Microsoft Azure

Learn what Azure is, understand its service families at a high level, and recognize where organizations use Azure in day-to-day operations.

What is it? (Simple Explanation)

Microsoft Azure is Microsoft’s cloud platform for building, running, and managing applications and IT resources in Microsoft-managed data centers worldwide.

Why do we need it?

Real-world Analogy

Think of Azure as a technology city with many managed utility services: power (compute), warehouses (storage), roads (networking), and identity checkpoints (Entra ID).

How it works (Technical)

Azure offers service families: compute, storage, networking, databases, identity, monitoring, and management. Users deploy resources under subscriptions and organize them with resource groups and tags. Management is available through Portal, CLI, PowerShell, and APIs.

Visual Representation

Azure Service Landscape (Foundation View)
Compute
VMs, App Services
Storage
Blob, Files
Identity
Entra ID
Management
Portal, CLI, PowerShell

Commands / Syntax

Azure CLI (optional preview)
az login
az account show
az group list --output table

Example (Real-world Use Case)

A retail company hosts internal dashboards and public APIs in Azure, stores files in Azure Storage, and manages employee access with Entra ID groups.

Hands-on

  1. Open Azure Portal and locate "All services".
  2. Find Compute, Storage, and Monitoring categories.
  3. Open Subscriptions and identify active subscription.
  4. Open Resource groups and observe naming patterns.
  5. Note one service your team could adopt first.

Try It Yourself

Write a 3-service starter stack for a basic web app in Azure using only foundation-level services.

Debugging Scenario

Issue: New user cannot see resources in Portal. Check: correct tenant, correct subscription, and RBAC assignment scope before checking resource health.

Interview Questions

Beginner

What is Azure?

Microsoft’s cloud platform delivering infrastructure and managed services globally.

Name 3 Azure service categories.

Compute, Storage, Identity (or Networking/Databases).

Why use Azure Portal?

It provides graphical management and discovery for services and resources.

Intermediate

When prefer CLI over Portal?

For repeatable automation, scripting, and multi-resource operations.

What is tenant context?

Directory boundary where identities live; wrong tenant leads to access confusion.

What is a common Azure adoption entry point?

Start with non-critical workloads and foundation governance patterns.

Scenario-based

Portal shows no resources after login.

Verify tenant/subscription selection and role assignment scope.

Need repeatable environment setup for demos.

Use CLI/PowerShell scripts instead of manual Portal clicks.

Team is new to cloud.

Begin with Azure fundamentals, naming conventions, and RBAC basics.

Real-world Usage

Azure is commonly used for app hosting, data services, enterprise identity, and platform modernization initiatives.

Summary

Azure is a broad cloud platform; at foundation level, focus on service families, management methods, and organization model.
