Overview
Azure, launched in 2010, is Microsoft's public cloud computing platform, offering a suite of services for building, deploying, and managing applications and services. It provides infrastructure as a service (IaaS), platform as a service (PaaS), and software as a service (SaaS) capabilities, supporting a wide array of programming languages, tools, and frameworks. Azure operates through a global network of Microsoft-managed data centers, enabling businesses to scale their operations, enhance agility, and reduce IT overhead.
The platform is designed to integrate with existing Microsoft technologies, making it a common choice for enterprises already invested in the Microsoft ecosystem. This includes seamless connections with Windows Server, SQL Server, and development tools like Visual Studio. Azure also emphasizes hybrid cloud solutions, allowing organizations to extend their on-premises infrastructure to the cloud and manage resources across both environments consistently. This approach is beneficial for companies seeking to maintain certain workloads on-premises for regulatory, security, or performance reasons, while leveraging cloud scalability for others.
Azure's service offerings span core computing, storage, networking, databases, analytics, artificial intelligence (AI), machine learning (ML), and Internet of Things (IoT). For developers, Azure offers comprehensive SDKs in languages such as Python, JavaScript, Java, .NET, and Go, alongside extensive documentation. This broad support facilitates application development and deployment across diverse technical stacks. The platform also provides a robust set of services for modern application development, including serverless computing with Azure Functions and container orchestration with Azure Kubernetes Service (AKS).
The platform is optimized for various enterprise use cases, from hosting web applications and data warehouses to running high-performance computing workloads and developing AI-powered solutions. Its compliance certifications, including ISO 27001, HIPAA, and GDPR, address the needs of regulated industries and organizations with stringent data governance requirements. Azure's commitment to security, global reach, and extensive service portfolio positions it as a significant competitor in the public cloud market, comparable to other major providers like Amazon Web Services (AWS) and Google Cloud Platform (GCP).

Pricing
Azure uses a pay-as-you-go model, where users are charged only for the services consumed. Pricing varies significantly across services, regions, and specific configurations (e.g., VM size, storage capacity, data transfer). Discounts are available for committed use through reserved instances, consumption plans, and specific service-level agreements. New users can typically start with a free account that includes a $200 credit and access to popular free services for 12 months. Detailed pricing information is available on the official Azure pricing page.
| Tier | Description | Details |
|---|---|---|
| Free Account | Introductory offer for new customers | $200 credit for 30 days, plus 12 months of free access to popular services like Virtual Machines, Azure Functions, and Azure Cosmos DB. |
| Pay-as-you-go | Standard consumption-based pricing | Charges incurred based on actual usage of compute, storage, networking, and other services. No upfront commitments required. |
| Reserved Instances | Discounted pricing for committed usage | Significant savings (up to 72% compared to pay-as-you-go) for committing to one-year or three-year terms for Virtual Machines and other services. |
| Savings Plans | Flexible savings for compute services | Commit to spending a fixed hourly amount for one or three years to receive discounts on eligible compute services. |

- Oracle Cloud Infrastructure (OCI): Oracle's cloud computing service, often chosen for enterprise database workloads and high-performance computing.
Getting started
To get started with Azure, you can create a free account and then deploy a simple resource, such as a web application using Azure App Service. The following Python example demonstrates how to deploy a basic Flask web application to Azure App Service using the Azure CLI.
# 1. Install Azure CLI
# On macOS: brew update && brew install azure-cli
# On Windows: Use MSI installer from Azure website
# On Linux: curl -sL https://aka.ms/InstallAzureCLIDeb | sudo bash
# 2. Log in to Azure
az login
# 3. Create a resource group
az group create --name MyResourceGroup --location eastus
# 4. Create an App Service plan (defines compute resources)
az appservice plan create --name MyAppServicePlan --resource-group MyResourceGroup --sku F1 --is-linux
# 5. Create the web app (Python 3.9 runtime)
az webapp create --resource-group MyResourceGroup --plan MyAppServicePlan --name MyPythonWebApp --runtime 'PYTHON|3.9'
# 6. Create a simple Flask application file (app.py)
# For example, create a file named 'app.py' with the following content:
# from flask import Flask
# app = Flask(__name__)
# @app.route('/')
# def hello_world():
# return 'Hello, Azure from Flask!'
# 7. Deploy the application code from local Git (assuming app.py is in current directory)
# First, set up local Git deployment
az webapp deployment source config --name MyPythonWebApp --resource-group MyResourceGroup --repository-type LocalGit
# Note: The output of the above command will provide a Git remote URL.
# Initialize Git in your project directory and add remote:
# git init
# git add .
# git commit -m "Initial commit"
# git remote add azure <GIT_REMOTE_URL_FROM_ABOVE>
# git push azure master
# 8. Browse to your deployed application
# The URL will be in the format: https://MyPythonWebApp.azurewebsites.net
# You can find the URL using:
az webapp show --resource-group MyResourceGroup --name MyPythonWebApp --query defaultHostName --output tsv
