This post explores the process of refactoring a warehouse inventory management system using event-driven architecture on AWS. It highlights the weaknesses of the current system and demonstrates how event-driven architecture can solve those problems. The post also discusses design considerations, the benefits of using CDC events, and provides a comparison of the performance and error rate between the v1 and v2 systems. Additionally, it includes a cost estimation for operating the new system and explores different event patterns used in the refactoring process.
