Building Distributed Applications with Event-driven Architecture • Eric Johnson • GOTO 2023

This presentation was recorded at GOTO Chicago 2023. #GOTOcon #GOTOchgo https://gotochgo.com Eric Johnson - Principal Developer Advocate for Serverless at AWS @ServerlessLand RESOURCES https://twitter.com/edjgeek https://linkedin.com/in/singledigit https://serverlessland.com https://serverlessland.com/reinvent2022/api311 ABSTRACT Event driven architecture helps companies build highly scalable, distributed applications. By decoupling application integrations, applications become more durable and easier to manage. In this session, learn common integration patterns seen in the wild and how to decouple them. Discover how you can use AWS messaging services to connect microservices and coordinate data flow using minimal custom code. Finally, you will learn how to reduce duplicate events and build in resiliency when your application has a failure by understanding and planning for idempotency.
