This document summarizes the goals and benefits of using Docker to modernize a company's enterprise software applications. It outlines the current pain points of slow, error-prone releases and high technical debt. The short term goal is to dockerize all applications, and the medium term goal is to move to the cloud. Leveraging Docker features like environments on demand and runtime configuration injection helped simplify releases. This reduced release time from around an hour to just 5 minutes, killed technical debt, and reduced operational costs.
