KEDA: Event Driven and Serverless Containers in Kubernetes - Jeff Hollan, Microsoft

Event driven and serverless architectures are defining a new generation of apps. However, to take full advantage of the serverless benefits of event driven, your application needs to scale and react to those events instantly - scaling from zero to potentially thousands of instances. These events may come in the form of queue and Kafka messages, or events from a cloud provider like AWS SQS or Azure Event Hubs. KEDA 1.0 is an open sourced component created in partnership with Red Hat and Microsoft Azure that provides event driven autoscaling for your Kubernetes workloads. In this demo-filled session, learn how to get started with KEDA, how customers are using it to efficiently scale and run event-driven apps, and how everything from a simple container to a serverless function can integrate seamlessly and scale natively in an event-driven and Kubernetes world.

I'm a little bit confused why scaling on queue length is better than scaling on CPU. Shouldn't the CPU increase to 100% before the queue starts to backlog? At which point the HPA will scale out the deployment. If the queue is backlogging and the CPU isn't at 100% why would scaling out (i.e. adding more CPU) help?
