The closing post of the series. The thread that connects all six patterns, the evolution from glue spaghetti to platform control plane, and why having architectural vocabulary changes how platform teams make decisions.
Hardcoding deployment strategy into pipelines creates a hidden coupling that makes platforms less reliable. The Strategy pattern explains how to make canary, blue/green, and progressive delivery first-class platform concerns.
Every platform connects systems that weren't designed to talk to each other. That connective tissue is glue — and in most platforms, it's 60-80% of what the team actually builds. Here's what glue is, where it lives, and how to design it intentionally.
Pipelines that run kubectl apply directly are automated but invisible. The Command pattern explains why GitOps is architecturally sound — not just a convention — and what you gain from separating the definition of a change from its execution.
Platform engineers apply design patterns every day without knowing it. This series bridges the gap between software architecture vocabulary and the real decisions you make in platform engineering.
