Event-driven architectures are becoming increasingly popular for building scalable and responsive systems. In this talk we will explore how WebAssembly (WASM) can enhance event-driven architecture on Kubernetes when combined with Knative and KEDA. We'll focus on building autoscaling event processing systems, showcasing practical examples, and discussing the benefits and challenges of this approach. Join us to learn about the exciting possibilities of integrating WASM into Kubernetes environments for more efficient and faster event processing at scale.
