Applicability

Use an Event-driven architecture when

  • you want to create a loosely coupled system
  • you want to build a more responsive system
  • you want a system that is easier to extend

Real world examples

  • Chargify, a billing API, exposes payment activity through various events (https://docs.chargify.com/api-events)
  • Amazon's AWS Lambda, lets you execute code in response to events such as changes to Amazon S3 buckets, updates to an Amazon DynamoDB table, or custom events generated by your applications or devices. (https://aws.amazon.com/lambda)
  • MySQL runs triggers based on events such as inserts and update events happening on database tables.
