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 2×4 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. Just like the toy bricks, containers provide a standard way to bundle applications for portability across any compatible system where they run. Need to scale up? Simple: add more “bricks.” Want to update a feature? Pop out one container and snap in another, without toppling the whole tower. Lego is magical in its modularity and flexibility: easily built, broken apart, and rebuilt. In software development, containers bring the same agility to software development. They isolate applications and their dependencies, just like individual Lego bricks are self-contained units. Such isolation ensures that just like a red 2×4 brick makes no difference whether it is in a castle or a spaceship, your application will be running identically whether it is on your laptop or inside a cloud data center. In this chapter, we put the pieces of container technology together and explore how those digital building blocks have constructed a new era in computing. At the end of this, you’re going to see how containers are the doors to innovation: making developers able to build, share, and deploy their digital creations with unimaginable ease and creativity.
