Why KEDA Was Needed: Autoscaling Beyond CPU and Memory

In this episode we explore how Dapr and KEDA—two CNCF graduated projects—are reshaping cloud-native application development and what that means for observability. From event-driven architectures to autoscaling and service runtime, we discuss how these building blocks fit into modern systems. We discuss major capabilities around resilience, scalability, observability and even agentic AI support.

Our guest for this episode is Yaron Schneider, co-creator of both Dapr and KEDA projects, and co-founder and CTO of Diagrid. He also brings years of leadership at Microsoft on scalable cloud architecture.
