EventBridge

Priority Tier 4 Domain 2: Design Resilient Architectures

Amazon EventBridge is a serverless service that uses events to connect application components, building scalable, event-driven applications. It routes events from various sources to consumer applications and supports both many-to-many routing through event buses and point-to-point integrations via EventBridge Pipes. (source_page: 10)

Learning Objectives

Core Functionality and Purpose

Amazon EventBridge facilitates building event-driven architectures by efficiently routing events from various sources to consumer applications.

Amazon EventBridge is a serverless service that uses events to connect application components, enabling the creation of scalable, event-driven applications. It routes events from various sources, such as homegrown applications, other AWS services, and third-party software, to consumer applications across an organization.

EventBridge Components and Routing Mechanisms

EventBridge offers distinct mechanisms for event routing based on application needs, providing a consistent way to ingest, filter, transform, and deliver events.

EventBridge provides flexible routing capabilities for different integration patterns.

Event Buses

EventBridge event buses are well suited for many-to-many routing of events between event-driven services. They provide a central point to manage event flows across various application components.
Use Cases:
  • Many-to-many routing of events between event-driven services

EventBridge Pipes

EventBridge Pipes are intended for point-to-point integrations between event sources and targets. They support advanced transformations and enrichment of events during transit.
Use Cases:
  • Point-to-point integrations between event sources and targets
  • Advanced transformations and enrichment of events

Practical Use Cases and Scenarios

EventBridge supports various integration patterns across AWS services and custom applications, offering automation and event-driven capabilities.

Amazon EventBridge can be used to create scheduled rules that invoke AWS Lambda functions. This functionality allows for the automation of routine tasks, such as starting and stopping an Amazon RDS database instance on a predefined schedule. This approach is serverless, low maintenance, and cost-effective, eliminating the need for application redesign to manage such schedules.
EventBridge can be utilized in conjunction with Amazon S3 Server Access Logging to track requests made to S3 objects. It is important to note, however, that EventBridge in this context tracks requests to objects and is not designed for detecting configuration changes to the S3 bucket itself.
While not the most secure or low-overhead solution, EventBridge could theoretically be used as part of a custom solution involving Amazon S3 and AWS Lambda for database credential rotation. However, such a setup would involve significant custom rotation logic and operational burden, making it an insecure and non-optimal choice compared to purpose-built, managed services like AWS Secrets Manager for this specific task.
