Azure Fundamentals Tutorial

Introduction to Microsoft Azure

Microsoft Azure is a cloud computing platform and infrastructure that Microsoft offers for building, deploying, and managing applications and services through a global network of data centers. This tutorial will guide you through the fundamental concepts of Azure, empowering you to start your cloud journey.

We'll cover core services, architectural concepts, and best practices to get you up and running quickly.

Core Azure Concepts

Understanding the building blocks of Azure is crucial. Here are some key components:

Regions and Availability Zones: Azure operates globally, with data centers organized into regions. Each region has multiple Availability Zones for high availability and fault tolerance.
Resource Groups: A logical container that holds related Azure resources for a solution. This helps manage and organize your deployments.
Azure Resources: Any manageable item in Azure. This includes virtual machines, storage accounts, virtual networks, databases, and more.
Azure Subscriptions: A logical container for Azure services that are associated with an account. It represents a billing boundary.

Essential Azure Services

Let's explore some of the most commonly used Azure services:

Compute Services:

Azure Virtual Machines (VMs): On-demand, scalable computing resources. You can run Windows and Linux operating systems.

# Example: Creating a VM using Azure CLI
az vm create --resource-group MyResourceGroup --name MyVM --image Ubuntu2204 --admin-username azureuser --generate-ssh-keys

Azure App Service: A fully managed platform for building, deploying, and scaling web apps, mobile backends, and APIs.
Azure Functions: A serverless compute service that enables you to run code without explicitly provisioning or managing infrastructure.

Storage Services:

Azure Blob Storage: Massively scalable object storage for unstructured data like text or binary data.
Azure Files: Fully managed file shares in the cloud that are accessible via the industry-standard Server Message Block (SMB) protocol.
Azure Queue Storage: A service for storing large numbers of messages that can be accessed from anywhere in the world.

Networking Services:

Azure Virtual Network (VNet): Provides the fundamental building blocks for your private network in Azure.
Azure Load Balancer: Distributes network traffic across multiple virtual machines or services.
Azure VPN Gateway: Enables you to create encrypted connections between your on-premises networks and Azure.

Database Services:

Azure SQL Database: A fully managed relational database service built for the cloud.
Azure Cosmos DB: A globally distributed, multi-model database service.

Getting Started: Your First Azure Deployment

Let's walk through a simple scenario to deploy a basic web application.

Sign up for an Azure account: If you don't have one, you can get a free trial.

Create a Resource Group:

az group create --name MyWebAppRG --location eastus

Deploy an App Service:

az appservice plan create --resource-group MyWebAppRG --name MyWebAppPlan --sku B1 --is-linux

az webapp create --resource-group MyWebAppRG --plan MyWebAppPlan --name myuniquewebappname --runtime "python|3.9"

(Replace myuniquewebappname with a unique name.)

Access your web app: Navigate to http://myuniquewebappname.azurewebsites.net in your browser.
