Building Event-Driven Architecture with AWS EventBridge

Event-driven architecture (EDA) has become essential for building scalable, loosely-coupled systems in the cloud. But what problems does EDA actually solve, and how do you implement it effectively with AWS services?

This hands-on session is designed for builders who want practical, working examples they can apply immediately. While recent presentations have covered EDA theory, we'll focus on implementation: diving deep into EventBridge rules with real code examples, exploring integrations with multiple AWS services, and walking through a complete working demo.

We'll start with the fundamentals—what event-driven architecture is, why it matters, and the common anti-patterns teams fall into when they try to solve integration challenges without EDA. You'll see how EventBridge serves as the backbone for decoupled communication and why it's often better than point-to-point integrations or polling-based solutions.

Then we'll dive deep into EventBridge rules with multiple practical examples: content-based filtering, pattern matching with complex conditions, and routing events to different targets based on attributes. You'll see these rules implemented in both the AWS Console and as code (CDK/CloudFormation), so you can choose the approach that fits your workflow.

We'll explore how EventBridge integrates with essential AWS services including Lambda, SQS, Step Functions, API Gateway, DynamoDB, and S3—with working code examples you can reference. To bring it all together, I'll share a real-world case study from the freight industry, showing how we used EventBridge to enable EDI integrations between Transportation Management Systems.

Whether you're new to event-driven patterns or looking to deepen your EventBridge expertise, you'll leave with practical code examples, architectural patterns, and hands-on knowledge you can implement immediately.

Target Audience: Developers and architects from beginner to intermediate levels who want to build event-driven systems with AWS. Best suited for builders seeking practical, working examples beyond theoretical concepts.
