Windows Azure logo (2010—2012)

Microsoft Azure, formerly known as Windows Azure, is a cloud computing service created by Microsoft for building, testing, deploying, and managing applications and services through Microsoft-managed data centers. It provides software as a service (SaaS), platform as a service (PaaS), and infrastructure as a service (IaaS) and supports many different programming languages, tools, and frameworks, including both Microsoft-specific and third-party software and systems.

Overview

Microsoft Azure was announced in October 2008 and released on February 1, 2010, as "Windows Azure" before being renamed to "Microsoft Azure" on March 25, 2014. Azure enables users to run virtual machines or applications in the cloud. It offers a wide range of services, including Azure Virtual Machines, Azure SQL Database, Azure Active Directory, and many others aimed at various business needs. Azure supports a broad selection of operating systems, programming languages, frameworks, databases, and devices.

Services

Azure provides more than 200 services that are categorized into 18 types, including computing, web, mobile, analytics, storage, and networking. Key services include:

• Azure Virtual Machines: Allows users to deploy a virtual machine in the cloud. This service is IaaS.
• Azure App Services: Provides a platform for hosting web applications, REST APIs, and mobile back ends. This service is PaaS.
• Azure Kubernetes Service (AKS): A managed container orchestration service based on Kubernetes.
• Azure Functions: Enables running event-driven, serverless computing functions.
• Azure Cosmos DB: A globally distributed, multi-model database service.
• Azure Cognitive Services: A collection of APIs and services that allow applications to see, hear, speak, understand, and interpret human needs using natural methods of communication.

Security

Security in Azure is a significant focus, with Microsoft implementing a wide range of security measures to protect data and ensure compliance with various standards and regulations. Azure Security Center provides unified security management and advanced threat protection across hybrid cloud workloads. With tools like Azure Active Directory for access management and Azure Sentinel for security information and event management, Azure aims to secure both applications and data.

Compliance

Microsoft Azure complies with a broad set of international and industry-specific compliance standards, such as ISO 27001, HIPAA, FedRAMP, SOC 1 and SOC 2, as well as country-specific standards like the UK G-Cloud. This makes Azure a viable option for a wide range of industries, including healthcare, government, finance, and education, which require strict compliance measures.

Development and Management Tools

Azure provides a range of tools for managing and developing applications on its platform, including:

• Azure Portal: A web-based application for managing all Azure services.
• Azure PowerShell: A set of cmdlets for managing Azure resources directly from the PowerShell command line.
• Azure CLI: A command-line tool for managing Azure resources.
• Azure DevOps Services: A suite of development tools for software teams to build, test, deploy, and manage applications and services.

Market Position and Competitors

Microsoft Azure is one of the leading cloud service providers, competing with Amazon Web Services (AWS) and Google Cloud Platform (GCP). Azure has seen significant growth and adoption across various industries due to its extensive service offerings, compliance, and security features.

Future Directions

Microsoft continues to invest in Azure, expanding its global infrastructure, introducing new services, and integrating artificial intelligence and machine learning capabilities to enhance its offerings. The focus on hybrid cloud environments, edge computing, and IoT (Internet of Things) represents key areas of growth and development for Azure.
