As a child, I spent so much time using Lego to build things, all the while thinking that there was no way these stupidly simple and standardized 2x4 bricks could be the origin of all the awesome possibilities. Little did I know that those colorful blocks were instilling in me the fundamental principle of modern software development. Just as Lego reinvented play, containers have fundamentally changed how we develop, package, and deploy applications. Now imagine your software as if it were a Lego construction. Containers are individual building blocks, standardized and endlessly combinable, each one representing a containerized component.
