Scaling deployments down to zero on Google Kubernetes Engine (GKE) can offer significant financial savings.
GKE does not natively offer scale-to-zero functionality, but it can be achieved by integrating the Kubernetes Event-driven Autoscaler (KEDA).
Scaling to zero is beneficial for minimizing costs in scenarios such as GPU-intensive workloads, applications with predictable downtime, seasonal applications, on-demand staging environments, event-driven applications, and development environments.
KEDA is an open-source, Kubernetes-native solution that enables scaling deployments based on various metrics and events, supporting scale-to-zero functionality.
