Amazon has two primary businesses. It is probably best known as a retail giant that sells books and all sorts of other products at http://www.Amazon.com. It has another very large business as a cloud computing provider, a business that serves corporations, government, and individuals alike. (I back up my computers to Amazon S3.) Amazon delivers infrastructure-as-a-service that lets businesses and developers build and host applications in Amazon data centers.
Amazon announced today a new service, called Amazon Workspaces. Amazon will use its cloud to deliver virtual Windows desktops to any Windows or Mac computer, iPad, Kindle Fire, or Android tablet. It will allow anyone to run a Windows (virtual) computer installed in an Amazon data center even though the customer is using a Macintosh, a different Windows computer, or a tablet. Each user gets his or her own 50 gigabyte to 100 gigabyte of disk space and 3.75 or 7.5 gigabytes of memory. The remotely hosted system should be able to run any Windows programs the user cares to install.
