LIDNUG : Reliable applications with messaging
1 like•623 views
Dennis van der Stelt discusses the importance of reliable systems design, emphasizing separation of concerns and reducing coupling in software architectures. He argues that monolithic designs lead to tightly coupled modules and proposes using messaging for improved agility and manageability in applications. The document also highlights the benefits of asynchronous and event-driven communication for achieving loose coupling and better performance.
