Part 3. Higher-level abstractions and orchestration

This part focuses on managing systems of components by using containers. Most valuable systems have of two or more components. Managing systems with a small number of components is manageable without much automation. But achieving consistency and repeatability is difficult without automation as the system grows.

Managing modern service architectures is complex and requires automated tooling. This part dives into higher-level abstractions such as service, environment, and configuration. You will learn how to use Docker to provide that automated tooling.
