Real-Life Implementations of Event-Driven Processes
summary
The talk explains how a digital platform was re-architected to event-driven microservices to avoid synchronous request dependencies, making each bounded context the single source of truth. It describes concrete implementations using Java, Kotlin, TypeScript and Python on cloud infrastructure and covers event emission, error handling, real-time monitoring of queues/processes, testing, CI/CD and language-specific handling of cloud queues, illustrated with real-life examples from market data, advertising-area assignment, offers and integrations with EDEKA.de, newsletter providers and external SOAP/REST APIs.
