Amazon Web Services (AWS), a collection of remote computing services, also called web services, make up a cloud-computing platform offered by Amazon.com. These services operate from 11 geographical regions across the world. The most central and well-known of these services arguably include Amazon Elastic Compute Cloud and Amazon S3. Amazon markets these products as a service to provide large computing-capacity more quickly and more cheaply than a client company building an actual physical server farm.
