Amazon, the world's largest retailer, not only uses Linux, but provides numerous enterprise-level services that leverage the power of Linux. In fact, Amazon has developed and maintains their very own Linux distribution named Amazon Linux. Amazon Linux was and is specifically built for Amazon's AWS EC2 (Elastic Compute) service that allows users to spin up virtual server instances quickly while only being charged for the amount of resources that the server actually consumes. Often, for small scale operations, the consumer will likely pay little or nothing when compared to a monthly subscription model. But back to the point, Amazon's AWS EC2 service also offers a plethora of additional Linux options including CentOS, Debian, Ubuntu, SUSE, and more. It would seem as though Amazon's success with the EC2 service is is in some ways directly related to the use and offering of Linux operating systems.
