AWS EventBridge

Introduction

This post is a hub of AWS EventBridge notes.

AWS EventBridge is a serverless event bus service that makes it easy to connect applications using data from your own applications, integrated Software-as-a-Service (SaaS) applications, and AWS services.

Key Features:

• Event-driven architecture: Simplifies the process of building event-driven applications.
• Serverless: Automatically scales and handles infrastructure management.
• Integrated with AWS services: Easily connects with other AWS services like Lambda, SQS, SNS, and more.
• Custom event buses: Create custom event buses for your applications.
• Schema registry: Automatically discovers and stores event schemas.

Example Use:

Microservices Synchronization

Case: Update the status of orders across different microservices.

Event: An order changes to “Shipped” in the inventory system.

Action: EventBridge distributes the event to logistics and billing services to initiate shipping and generate the invoice.

sample event

{
  "source": ["app.orders"],
  "detail-type": ["Order Shipped"],
  "detail": {
    "orderId": "12345",
    "status": "Shipped"
  }
}
