What is Microsoft Azure?

Microsoft Azure is a cloud computing platform launched by Microsoft in 2010, offering over 200 services, including computing, storage, databases, networking, analytics, AI, and more. Azure provides scalable, on-demand resources over the internet, enabling businesses and developers to build, deploy, and manage applications without investing in physical infrastructure. Like AWS, Azure aligns with the NIST Cloud Computing Definition (as discussed in Cloud Computing Basics), supporting on-demand self-service, broad network access, resource pooling, rapid elasticity, and measured service. It covers all cloud service models (IaaS, PaaS, SaaS) and deployment models (public, private, hybrid, community).

Azure is known for its integration with Microsoft products (e.g., Windows Server, Office 365), strong hybrid cloud capabilities, and enterprise-grade security, making it a top choice for organizations using Microsoft ecosystems.

Azure Core Concepts

1. Regions and Availability Zones

• Region: A geographical area (e.g., East US, West Europe) with multiple data centers.
• Availability Zone (AZ): Isolated locations within a region for high availability and fault tolerance.
• Use Case: Deploy an OOP-based banking app (e.g., with BankAccount class) across East US AZs for redundancy.
• Best Practice: Select regions close to users for low latency.

2. Azure Global Infrastructure

Azure’s global network ensures reliability and performance. For example, host a Git repository on Azure DevOps while deploying an app in a different region.

3. Pay-as-You-Go and Free Tier

Azure bills based on usage (e.g., VM hours, storage GB). The Azure Free Tier includes:

• 750 hours/month of Linux/Windows B1S VMs for 12 months.
• 5 GB of Blob Storage.
• 250 GB of Azure SQL Database.
• Use Case: Deploy a small Python app with OOP classes for free to practice.

• Polymorphism: Use Azure SDKs for polymorphic behavior (e.g., Payment interface with CreditCardPayment interacting with Cosmos DB).
• Example:
  python

  # BankAccount.py
  class BankAccount:
      def __init__(self, account_holder, balance):
          self.__account_holder = account_holder
          self.__balance = balance
      
      def deposit(self, amount):
          if amount > 0:
              self.__balance += amount
              # Log to Azure Monitor
              from azure.monitor.opentelemetry import export_logs
              export_logs(f"Deposited {amount} to {self.__account_holder}")
              return True
          return False
  Deploy on Azure Functions, triggered by HTTP requests.
