Overview
This objective covers the use of messaging and event services, primarily Amazon EventBridge, to build event-driven applications. EventBridge acts as a serverless event bus, enabling integrations between AWS services, SaaS applications, and your applications.
Core Concepts
- EventBridge facilitates communication between services through events, enabling asynchronous processing and scalability.
- The core architecture involves producers publishing events to EventBridge, and consumers subscribing to events based on rules.
- EventBridge does not provide strict ordering guarantees. Use a FIFO-capable messaging service when strict ordered delivery is required.
Exam Tips
- Understand the concept of event routing and how EventBridge rules are defined.
- Recognize the different targets that EventBridge can route events to, such as Lambda functions, SQS queues, and SNS topics.
