Technical context

Feature store (e.g. Feast)CI/CD systems (e.g. GitLab CI, Jenkins)Serving platforms (e.g. KServe, Seldon)

Principles & goals

Separate model lifecycle management from infrastructure configuration.Automate validation, deployment and rollback steps.Ensure observable behavior and measurable SLAs for inference.

Use cases & scenarios

Compromises

  • Inconsistent model states without strict registry policies.
  • Security vulnerabilities from unprotected model access.
  • Cost overruns due to faulty autoscaling rules.
  • Use declarative configuration for reproducibility.
  • Separate staging and production paths and test automatically.
  • Instrument metrics and alerts before production rollout.

I/O & resources

  • Trained model artifacts
  • Model metadata and versioning entries
  • Serving configurations and routing rules
  • Deployed endpoints and service records
  • Monitoring metrics and audit logs
  • Release and rollback reports

Description

Model orchestration coordinates model lifecycle, deployment and request routing of ML models in production. It combines model versioning, serving, A/B testing and monitoring into repeatable workflows. The goal is high availability, consistent inference and automated rollouts across platforms. Implementations require integration with feature stores, CI/CD and observability stacks plus governance and security policies.

✔

  • Shorter time-to-production through repeatable workflows.
  • Improved availability and consistent inference routing.
  • Safe controlled rollouts and rollback mechanisms.

✖

  • Requires integration into existing platform and CI/CD stacks.
  • Complexity increases with the number of models and versions.
  • Platform dependencies can limit portability.

  • P95 inference latency

    95th percentile of response times for model endpoints.

  • Model promotion rate

    Share of successfully promoted models per time period.

  • Error rate (inference-related)

    Share of failed or rejected inference requests.

Kubeflow Pipelines example

Pipeline that orchestrates training, packaging and deployment.

KServe for serverless serving

Using KServe for scalable serving and model versioning.

MLflow model registry integration

Registry-based promotion of models from staging to production.

1

Define model registry and versioning rules; connect to CI/CD.

2

Set up serving infrastructure and routing rules.

3

Implement observability, tests and rollback mechanisms.

4

Train operations teams and establish governance policies.

⚠️ Technical debt & bottlenecks

  • Ad-hoc scripts for deployment instead of declarative pipelines.
  • Incomplete monitoring setup that drops traces.
  • No standardization of model metadata structure.
Model registry usageNetwork and latency bottlenecksObservability data volume
  • Directly overwriting running models without tests.
  • Relying entirely on proprietary platform features for critical paths.
  • Deployment without SLA and security checks.
  • Incomplete version metadata prevents reproductions.
  • Missing cost control with aggressive autoscaling.
  • Overly fine-grained canary splits without statistical significance.
