What is it?
Microsoft Azure, commonly referred to as 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. Azure is the largest commercial cloud vendor by revenue, although that designation stems in part from the company's "power of incumbency in Office 365 Commercial and Microsoft 365," which may artificially inflate the company's "pure cloud" revenue totals.
