Please give me brief description about microsoft azure, AWS and cloud computing.

Cloud computing is internet-based computing whereby shared resources, software, and information are provided to computers and other devices on-demand.Large enterprises have been using the cloud for years to gain scalability and to move quickly to capture new business opportunities without making additional investments in IT staff and equipment. Amazon Web Services :- AWS has a diverse customer base and a broad range of use cases in enterprise and mission-critical applications. It has the largest share of compute capacity of all other providers in the market. This has enabled AWS to attract an ecosystem of open-source tools, and over a thousand technology partners that have: Licensed and packaged their software to run on AWS Integrated their software with AWS capabilities Deliver add-on services. AWS also has a tiered and competency-badged network of partners that provide application development expertise, managed services and professional services such as data center migration. That ecosystem, along with AWSâ??s training and certification programs, makes it easier to adopt and operate AWS in a best practice fashion. Microsoft Azure ;- Microsoft Azure encompasses integrated IaaS and PaaS components that operate together. Microsoft has been rapidly rolling out new features and services, and has a vision of infrastructure and platform services with leading stand-alone offerings that seamlessly extend and operate with on-premises Microsoft infrastructure. Microsoft has become less reliant on its Windows franchise, and Azureâ??s support for Linux and other open-source technologies is improving. Azure is not the size of AWS, but Microsoft has been working hard to match Amazonâ??s services and flexibility. Many organizations consider it a contender, and base their vendor decision on factors other than technical capabilities. And Microsoftâ??s brand, existing customer relationships, history of running global-class consumer internet properties and deep investments in engineering and innovation have enhanced its status as a strategic cloud IaaS provider. Azure is generally available in 26 regions around the world, and has announced plans for 8 additional regions. Geographic expansion is a priority for Azure because it enables its customers to achieve higher performance and it supports their requirements and preferences regarding data location. read less
