We are used to treating coupling as the necessary evil. Hence, we aim to break systems apart into the smallest services possible, in the ever-lasting quest of decoupling everything. But what results are we getting by following this reasoning? - Instead of the promised land of evolvable systems, many such “decouple everything” endeavors lead straight into the chains of distributed monoliths. Can we do better? What if there is a better way to handle coupling in distributed systems? Or even, what if instead of fighting coupling, we can use it as a heuristic for designing systems that are actually evolvable and maintainable? That’s exactly what you will learn in this session: what coupling is, and how you can use it as a design tool. We will start by taking a journey through time, and explore the different models of evaluating coupling. Next, we will combine the existing knowledge into a coherent model - a simple function for evaluating a system’s decomposition into components. This function will allow you to assess the expected effort for evolving a system and use it as a heuristic for optimizing architectural design decisions.
