Scaling and Auto-Scaling Model Endpoints
Kubernetes HPA for model pods, traffic-based scaling, A/B deployment, canary releases.
Why Auto-Scaling
Inference traffic is rarely flat. Provisioning for peak load wastes money at night; provisioning for average load fails at peak. Auto-scaling adjusts the number of replicas automatically based on demand so you pay for what you use and stay responsive.
Pods and Replicas
On Kubernetes a model server runs as a Deployment of identical pods (replicas). Scaling means changing the replica count. A Service load-balances requests across whatever replicas exist.
