James Beswick, a developer advocate for AWS Serverless, presents an in-depth look at Serverlesspresso, an event-driven coffee ordering app built with serverless architecture. He explores the design decisions, challenges, and lessons learned in creating this production-ready application that handles thousands of orders per day. Beswick details how they combined Amazon EventBridge and AWS Step Functions to orchestrate events across microservices, creating a scalable and cost-effective solution. The presentation covers key aspects of event-driven architecture, including workflow design, real-time communication with IoT Core, and patterns for building extensible serverless applications. Beswick emphasizes the power of combining orchestration and choreography in serverless systems, demonstrating how this approach can lead to more flexible, maintainable, and cost-efficient solutions. The talk provides valuable insights for developers looking to leverage serverless technologies in building complex, event-driven applications.
