Key differences between Azure and Amazon Web Services (AWS)

Azure

Azure, officially known as Microsoft Azure, is a comprehensive cloud computing service created by Microsoft for building, testing, deploying, and managing applications and services through Microsoft-managed data centers. It provides a wide array of cloud services, including those for computing, analytics, storage, and networking. Users can pick and choose from these services to develop and scale new applications, or run existing applications, in the public cloud. Azure supports a broad selection of operating systems, programming languages, frameworks, databases, and devices, allowing developers to use the tools and technologies they are familiar with. Launched in February 2010, Azure has since become one of the leading cloud platforms in the industry, competing with other giants such as Amazon Web Services (AWS) and Google Cloud Platform (GCP). Azure is designed to help businesses manage challenges and meet their organizational goals by providing cloud solutions that are scalable, reliable, and highly available.
