Importance of Boundaries and Context in Software Architecture

Setting clear boundaries and defining context in software architecture are crucial for developing high-quality and scalable systems. Boundaries help in isolating different functionalities and features within a system, allowing for independent development and testing. Vertical slices, which focus on specific features or capabilities, replace traditional layer-based architectures. By organizing code based on vertical slices, teams can work more efficiently, make changes to specific features, and adopt new technologies without rewriting the entire system. Context-driven development also emphasizes the use of messaging and asynchronous communication, enabling scalable and resilient systems. Asynchronous messaging not only enables loose coupling between components but also facilitates code isolation and unit testing. Additionally, setting clear boundaries and leveraging messaging technologies enhance the governance and maintainability of the system.
