🔗 When not to use event-driven architecture (EDA)

When is Event-Driven Architecture (EDA) the wrong choice? The article outlines seven scenarios where using EDA could complicate a system rather than add value. For instance, it warns against implementing EDA for simple CRUD applications or when strong consistency is critical, such as in banking or payment processing. It further emphasizes the importance of immediate user responses, stating users typically don’t want to hear that their payment is in limbo. It advises against using an event-driven approach when only a single consumer exists or when a team lacks operational knowledge necessary for managing the complexities of EDA. Ultimately, the piece serves as a guide for architects to avoid common pitfalls, promoting more coherent architectural choices.
