Welcome to the fundamental guide to Microsoft Azure. This tutorial will introduce you to the core concepts of cloud computing and how Azure empowers you to build, deploy, and manage applications and services on a global scale.
What is Cloud Computing?
Cloud computing is the delivery of computing services—including servers, storage, databases, networking, software, analytics, and intelligence—over the Internet (“the cloud”) to offer faster innovation, flexible resources, and economies of scale. You typically pay only for cloud services you use, helping you lower your operating costs, run your infrastructure more efficiently, and scale as your business needs change.
Why Microsoft Azure?
Azure is a comprehensive cloud platform that offers a wide range of services for building and managing applications. It provides:
- Global Infrastructure: Datacenters worldwide ensure low latency and high availability.
- Hybrid Capabilities: Seamlessly integrate your on-premises infrastructure with the cloud.
- Extensive Services: From virtual machines and databases to AI and IoT, Azure has you covered.
- Security and Compliance: Robust security features and adherence to numerous compliance standards.
- Developer Tools: Integrated development environments and tools to accelerate your workflow.
Core Azure Concepts
Understanding these foundational concepts is key to navigating Azure:
1. Regions and Availability Zones
Azure organizes its services into geographic regions. Each region consists of multiple data centers. Availability Zones are physically separate locations within an Azure region that provide fault tolerance against datacenter failures.
2. Azure Resources
Everything you create and manage in Azure is a resource. Examples include Virtual Machines, Storage Accounts, Virtual Networks, and Web Apps. These resources are grouped into resource groups for easier management.
3. Resource Groups
A resource group is a logical container that holds related Azure resources for a solution. You can manage, delete, and control access to resources collectively by managing their resource group.
4. Azure Subscriptions
An Azure subscription provides a management boundary for your Azure services. It's where you manage billing and access for your Azure resources.
Getting Started: Your First Azure Resource
Let's walk through creating a simple resource – a Storage Account. This is essential for storing various types of data.
Steps to Create an Azure Storage Account:
- Sign in to the Azure portal: Go to portal.azure.com and log in with your Azure account.
- Navigate to Storage Accounts: In the Azure portal, search for "Storage accounts" and select it.
- Create a Storage Account: Click the "+ Create" button.
- Configure Basics:
- Subscription: Choose your Azure subscription.
- Resource group: Click "Create new" and give it a name (e.g.,
my-azure-basics-rg). - Storage account name: Enter a globally unique name (e.g.,
myazurebasicsstorage12345). - Region: Select a region close to you.
- Performance: Choose "Standard".
- Redundancy: Select "Locally-redundant storage (LRS)" for this tutorial.
- Review and Create: Click "Review + create", then "Create".
Once deployed, you'll have a basic storage account ready to hold your data.
Azure CLI and PowerShell
For more efficient and automated management, Azure offers powerful command-line tools:
- Azure CLI: A cross-platform command-line experience for managing Azure resources.
- Azure PowerShell: A module for PowerShell that enables you to manage Azure resources.
Example: Creating a Resource Group with Azure CLI
First, ensure you have the Azure CLI installed and are logged in (az login).
