Welcome to the foundational concepts of Microsoft Azure. This guide will walk you through the core principles, services, and benefits of using Azure to build, deploy, and manage your applications and services.

What is Microsoft Azure?

Microsoft Azure is a cloud computing platform and infrastructure created by Microsoft. It provides a wide range of cloud services, including computing, analytics, storage, and networking, to help organizations build and scale their applications. Azure offers a global network of Microsoft-managed datacenters that host the services.

Key Concepts

• Regions and Availability Zones: Azure services are deployed in geographic regions. Each region has multiple Availability Zones, which are physically separate locations within a region, providing high availability and disaster recovery.
• Resource Groups: A logical container for Azure resources. Resource groups help manage and organize related resources for an Azure solution.
• Azure Resources: Any manageable item available through Azure. For example, virtual machines, storage accounts, virtual networks, and web apps are all Azure resources.
• Azure Subscriptions: A logical container that holds Azure services and resources. It's used for billing and managing access to your Azure resources.

Core Azure Services

Compute Services

Azure offers various compute services to run your applications:

• Virtual Machines (VMs): On-demand, scalable computing resources. You can run Windows and Linux VMs in Azure.
• Azure App Service: A fully managed platform for building, deploying, and scaling web apps and mobile backends.
• Azure Functions: An event-driven serverless compute platform that allows you to run small pieces of code, or "functions," in the cloud without explicit infrastructure management.
• Azure Kubernetes Service (AKS): A managed Kubernetes service that simplifies deploying, managing, and scaling containerized applications.

Storage Services

Azure provides robust and scalable storage solutions:

• Azure Blob Storage: Massively scalable object storage for unstructured data like text or binary data.
• Azure File Storage: Fully managed cloud file shares accessible via SMB protocol.
• Azure Queue Storage: A service that stores large numbers of messages that can be accessed from anywhere in the world via HTTP or HTTPS.
• Azure Table Storage: A NoSQL key-attribute store for unstructured data.

Networking Services

Azure networking services enable secure and reliable connections:

• Virtual Network (VNet): A fundamental building block for your private network in Azure. It provides a wide range of Azure networking capabilities.
• Azure Load Balancer: Distributes incoming traffic across multiple VMs.
• Azure VPN Gateway: Enables secure, cross-premises connectivity between your on-premises networks and your Azure VNets.

Getting Started with Azure

To begin your Azure journey:

1. Create an Azure account: Sign up for a free trial or a pay-as-you-go subscription.
2. Explore the Azure Portal: The Azure portal is a web-based interface for managing your Azure resources.
3. Learn about Azure Architecture Center: Find best practices, reference architectures, and design patterns.
4. Practice: Deploy your first application or set up a virtual machine to get hands-on experience.
