Amazon Web Services (AWS) is the world's largest cloud service provider. Since 2006, the company has been offering customers various elements of a virtual IT infrastructure in the form of web services. Today AWS offers about 70 cloud services deployed on the basis of more than a hundred of its own data centers located in the United States, Europe, Brazil, Singapore, Japan, and Australia. Services include computing power, secure storage, analytics, mobile applications, databases, IoT solutions, and more. Customers pay only for the services they consume, dynamically expanding or contracting cloud resources as needed.   Through cloud computing, companies do not need to pre-plan the use of servers and other IT infrastructure and pay for all this for several weeks or months in advance. Instead, they can deploy hundreds or thousands of servers in minutes and achieve results quickly.   Today, Amazon Web Services provides a highly reliable, scalable, infrastructure platform in the cloud that powers hundreds of thousands of organizations in every industry and government in nearly every country in the world.
