Event-Driven Architecture & Messaging

Distributed Systems & Scalability, System Design /

As systems grow and move toward microservices, direct synchronous communication becomes a bottleneck.Event-driven architecture (EDA) helps systems scale by allowing services to communicate asynchronously using events and messages. In this blog, we’ll cover event-driven architecture, message queues vs event streams, and when to use each. Synchronous vs Asynchronous Communication Synchronous Communication Example:Service A calls Service
