From a single LLM pilot to a governed AI platform
š When a FortuneāÆ500 sales team tried to push a single LLM proofāofāconcept into production, they soon hit a wall of latency spikes, runaway token bills and auditāaudit gaps.
That scenario is becoming the norm: legacy data silos, adāhoc model serving on isolated VMs, and missing observability turn a promising pilot into a 12āmonth nightmare.
What saved them? A disciplined enterprise AI roadmap that turned chaos into a repeatable, measurable process from MVP to a multiātenant, governed platform.
API gateway (Envoy or AWS API GW) ā terminates traffic, enforces OAuth2, injects request IDs.
Orchestration layer (Kubernetesābased Airflow/Temporal) ā coordinates pipelines, adds circuitābreakers.
Model layer ā mix of hosted LLMs (gptā4āturbo, Claude) and private fineātuned models behind vLLM.
Embedding service + vector DB (Pinecone/Qdrant) ā stores dense vectors with TTL eviction.
Observability stack ā OpenTelemetry ā Jaeger, Prometheus + Grafana for latency, token use, GPU.
š§ The impact is immediate: 95āÆ% of queries stay under 50āÆms, 30āÆ% token spend drops, and compliance logs capture every request ID for GDPR audits.
ā”ļø Latency down to subā50āÆms, token spend shrinks dramatically, and auditāready logs turn weeks of compliance work into days.
From a business angle, the roadmap delivered $1.5āÆM annual labor savings, doubled crossāsell conversion, and cut audit prep time from weeks to days.
For CTOs, the lesson is clear ā skip the āquickālaunchā LLM and embed governance, caching, and observability from dayāÆone.
Plavno helps stitch the plumbing ā from API gateways to vector stores ā so you can move from notebook to production without the 12āmonth slog.
