This document discusses how Docker is changing IT infrastructure and processes. It notes that containers represent the next major infrastructure shift, following shifts from mainframe to PC, bare metal to virtualization, and data centers to cloud. Containers can help reduce complexity compared to traditional infrastructure by allowing applications to run consistently across various environments. The document argues that Docker can help developers build, test, and deploy applications faster and help organizations innovate more by reducing costs spent on infrastructure maintenance. It provides examples of large companies that have adopted Docker Enterprise Edition and realized benefits like increased development productivity and reduced infrastructure costs.
