Amazon Web Services, Inc. (AWS) is a subsidiary of Amazon that provides on-demand cloud computing platforms and APIs to individuals, companies, and governments on a metered, pay-as-you-go basis. Often, clients will use this in combination with autoscaling (a process that allows a client to use more computing in times of high application usage and then scale down to reduce costs when there is less traffic).
These cloud computing web services provide various services related to networking, computing, storage, middleware, IOT, and other processing capacities, as well as software tools via AWS device farms. This frees clients from managing, scaling, and patching hardware and operating systems.
