MLOps Platform Demo

Production-shaped inference demo for the portfolio site. The model is intentionally small: logistic regression coefficients trained with scikit-learn and exported to JSON so the runtime stays light enough for the homelab.

Endpoints

• GET /healthz reports service, track, and active model metadata.
• POST /predict scores service health risk from latency, error rate, CPU, memory, and queue depth.
• GET /metrics exposes Prometheus metrics for request count, latency, errors, model version, confidence, and drift score.

Model Rollout

• MODEL_VERSION=v1, MODEL_TRACK=blue is the stable route.
• MODEL_VERSION=v2, MODEL_TRACK=green is the canary route.
• Kubernetes service selectors choose the active track, so rollback is a service selector change instead of an image rebuild.
