Kubernetes Event-driven Autoscaling with KEDA

on YouTube ↗37m

" summary

KEDA provides event-driven autoscaling by adding a ScaleObject CRD that creates an HPA per ScaleObject and runs an operator that handles zero→one while HPA handles one→N, so workloads can scale to zero and back. Demo uses RabbitMQ + Helm and a publisher job, hits a configured max 30 replicas and returns to zero successfully. KEDA exposes Prometheus metrics, supports 50+ scalers, triggerAuthentication/cluster credentials (Vault, Azure Key Vault, pod identities), and can spawn ScaleJobs for batch workloads.
