Inside Event-Driven Architecture

When building modern distributed backend systems especially microservices, one of the most critical design decisions you will make is how those services talk to each other. If services are too tightly coupled, your entire platform becomes fragile. This communication between services is known as service interaction. Broadly speaking, interactions fall into two categories: synchronous (waiting for a the response) and asynchronous (firing a call and moving on). In this blog, we’ll explore: Different types of service interactions. Dive into Event-Driven Architecture. Real-world patterns, use cases & types. What is Service Interaction? In a microservices architecture, multiple independent services collaborate to power an application. The communication between them is called service interaction, and it can be broadly classified into 3 types: Time-Driven Interaction Request-Driven Interaction Event-Driven Interaction 1. Time-Driven Interaction (Synchronous) In a time driven system, actions ar
