When it comes to cloud operating system popularity, Ubuntu Linux is, by far, the most popular operating system on Amazon Web Services (AWS). According to the Cloud Market’s latest analysis of operating systems on the Amazon Elastic Compute Cloud (EC2), Ubuntu has over 364,000 images with only generic Linux images surpassing it. Now, Canonical, Ubuntu’s parent company, is seeking to further its domination by offering premium Ubuntu Pro Linux images to Amazon Web Services (AWS). These images come with Canonical’s standard Ubuntu Amazon Machine Images (Amazon AMIs), plus automatically enabled key security and compliance subscriptions. In short, Ubuntu Pro is optimized by AWS Ubuntu, complete with security and support.
