Event-Driven Architecture (EDA)

EDA is a software architecture paradigm promoting the production, detection, consumption of, and reaction to events. In 2025, it is the backbone of real-time, scalable, and decoupled systems.

When to Use

• When strict decoupling is required (Producer doesn't know Consumer).
• High-volume, bursty traffic (using buffering queues).
• Asynchronous workflows (e.g., "User Signed Up" -> Send Email, Create Wallet, Analytics).
• Real-time updates (WebSockets/Push).
