Stability, control and long-term maintainability in backend systems Dependencies are everywhere in modern software development. Frameworks, libraries, external services, and specialized tools help accelerate development and avoid reinventing existing solutions. In many situations, this is a reasonable choice. A dependency can reduce development time, provide proven functionality, and simplify complex implementations. However, every dependency also introduces a trade-off that is often invisible at first: part of the system’s behavior is no longer fully controlled by the people building it. Solving problems today, creating complexity tomorrow Adding a dependency usually solves an immediate problem. A feature is implemented faster, with less effort, and the system moves forward quickly.…
