Exploring Event-Driven Architecture: A Beginner's Guide for Cloud Native Developers
Classical request/response architecture is driven by procedure calls, where a caller waits for the call to finish, and the call continues until the work is done. Each incoming call is broken into smaller procedure calls, which may in turn call other procedures. In contrast, event-driven architecture (EDA) is driven by events such as user actions, sensor outputs, or messages from other programs/threads, which determines the execution flow.
