LLMOps Platform Engineering

Design and operate an internal LLM platform that supports rapid experimentation without compromising reliability, cost, or compliance.

When to Use This Skill

• Building an internal platform for teams to deploy and manage LLM-powered features
• Designing CI/CD pipelines that include model evaluation gates
• Setting up A/B testing infrastructure for model versions
• Creating Kubernetes-based model serving infrastructure
• Establishing governance workflows for model promotion

Prerequisites

• Kubernetes cluster with GPU node pools (or cloud inference API access)
• Container registry (Harbor, ECR, GCR, or ACR)
• CI/CD system (GitHub Actions, GitLab CI, or Argo Workflows)
• Observability stack (Prometheus + Grafana + OpenTelemetry)
• Model registry (MLflow or custom metadata store)

Outcomes

• Standardized path from experiment to production
• Safe model rollout with quality and safety gates
• Repeatable infra modules for inference, vector DB, and observability
• Clear ownership model across platform, app, and security teams

Reference Architecture

1. Control Plane: model registry, prompt/version catalog, policy checks, eval pipeline.
2. Data Plane: inference gateway, vector database, cache, feature store.
3. Ops Plane: telemetry, alerting, SLO dashboards, cost analytics.
4. Security Plane: IAM boundaries, secret rotation, content filters, audit logs.
