Phase 8 · Serverless & Event-Driven Architecture

Topics

Event-Driven Architecture Basics

Part of the Cloud Computing Roadmap.

Summary

Designing systems where components communicate by producing and reacting to events, rather than calling each other directly — improving decoupling and scalability, at the cost of some added complexity in tracing a full flow.

How to Learn This

  • 1Diagram a hypothetical event-driven flow: an event produced by one service, consumed by another.
  • 2Learn why event-driven architecture decouples services, letting them scale and fail independently.
  • 3Understand the added debugging complexity: tracing a request across asynchronous event boundaries.
