Amazon Web Services (AWS) is a collection of remote computing services, also called web services that make up a cloud computing platform by Amazon.com. The well-known and most central of these services are Amazon S3 and Amazon EC2. The service has been advertised as providing a large computing capacity much cheaper and faster than building a physical server farm.
AWS has been located in 11 geographical “regions”: US West (northern California), US East (Northern Virginia), where the majority of AWS servers are based, US West (Oregon), Europe (Ireland and Germany), Brazil (São Paulo), Southeast Asia (Singapore), Australia (Sydney) and East Asia (Tokyo and Beijing). Every Region is totally contained within a single country and all of its services and data stay within the designated Region.
