Azure Fundamentals☝

This article is all about my understandings on Azure fundamentals. 

1️⃣ What is Microsoft Azure?

Azure is Microsoft’s cloud computing platform, offering services for computing, storage, networking, databases, AI, and more. It helps businesses and individuals build, deploy, and manage applications and services without needing physical hardware.

🔹 On-Premises vs. Cloud: Instead of maintaining physical servers, Azure lets you run everything in the cloud.
🔹 Pay-as-you-go Model: You only pay for what you use—no upfront infrastructure costs.

2️⃣ Key Azure Services Categories

Azure offers a variety of services across different categories. Here are some of the most important ones:

✅ Compute (Running Applications & Workloads)

  • Azure Virtual Machines (VMs) – Cloud-based servers for running applications.

  • Azure App Services – Host and manage web apps without managing the infrastructure.

  • Azure Functions – Serverless computing to run event-driven code.

✅ Storage (Saving Data in the Cloud)

  • Azure Blob Storage – Stores large amounts of unstructured data (like images, videos, backups).

  • Azure Files – Cloud-based file shares, similar to an on-premises file server.

  • Azure SQL Database – A fully managed relational database service.

✅ Networking (Connecting Applications & Users)

  • Azure Virtual Network (VNet) – A private cloud network to connect resources securely.

  • Azure Load Balancer – Distributes traffic to ensure high availability.

  • Azure VPN Gateway – Connects on-premises networks securely to Azure.

✅ Security & Identity

  • Azure Active Directory (Azure AD) – Manages users, authentication, and access control.

  • Azure Key Vault – Stores sensitive information like API keys and passwords.

✅ AI & Analytics

  • Azure Machine Learning – Train and deploy ML models in the cloud.

  • Azure Synapse Analytics – Enterprise-level data warehousing and analytics.

3️⃣ Core Azure Concepts

✔️ Regions & Availability Zones – Azure has data centers worldwide to ensure high availability and redundancy.
✔️ Azure Resource Manager (ARM) – A framework for managing Azure resources using templates.
✔️ Subscriptions & Resource Groups – Organizing resources into logical groups for better management.
✔️ Pay-As-You-Go Pricing – Costs are based on usage, and there are free-tier services for beginners.

4️⃣ Azure Certifications for Beginners 🏅

If you’re just starting out, the AZ-900: Microsoft Azure Fundamentals exam is a great first step. It covers:
✅ Cloud computing basics
✅ Azure core services
✅ Security, compliance, and pricing

5️⃣ How to Start Learning Azure?

✅ Microsoft Learn – Free interactive tutorials
✅ Azure Free Account – Get $200 free credit
✅ Hands-on Labs – Try services like VMs, Storage, and Networking
✅ YouTube & Udemy Courses – Great for guided learning

6️⃣ Why Learn Azure?

💼 In-demand skills – Cloud computing is one of the fastest-growing fields.
💰 High-paying jobs – Roles like Azure Administrator, Cloud Engineer, and Data Engineer are in high demand.
🚀 Career Growth – Learning Azure opens doors to roles in DevOps, Data Engineering, AI, and Cybersecurity.
