Abstract
Event-driven systems are everywhere, but choosing the right approach can be tricky. Should you use simple webhooks, a message queue like Kafka, or something Go-native like Watermill? This talk explores the trade-offs between webhooks and pub/sub systems, focusing on scalability, reliability, and maintainability in Go applications. We'll walk through real-world scenarios—such as SaaS integrations, real-time notifications, and high-throughput data pipelines—and provide clear decision-making guidelines. Whether you're building a small Go service or architecting a large event-driven system, you'll leave with a solid framework for making the right choice.
