Cost Management Rules

OSVauco-NMTMD-GCOS | GCP Agent Master Repo

1. Budget Alerts

gcloud billing budgets create \
  --billing-account="${BILLING_ACCOUNT_ID}" \
  --display-name="Agent Platform Budget" \
  --budget-amount=500USD \
  --threshold-rule=percent=0.5,basis=CURRENT_SPEND \
  --threshold-rule=percent=0.8,basis=CURRENT_SPEND \
  --threshold-rule=percent=1.0,basis=CURRENT_SPEND

2. Resource Labeling

All GCP resources MUST carry:

Label Key	Example	Purpose
env	prod/dev/staging	Environment
team	osvaucoe	Cost attribution
cost-center	ai-platform	Finance
agent	orchestrator/rag	Per-agent tracking

3. Cloud Run Cost Controls

gcloud run deploy ${SERVICE} \
  --max-instances=10 \
  --concurrency=80 \
  --timeout=300

• CPU throttling on for non-latency-critical agents
• min-instances=1 only for latency-sensitive services

4. Vertex AI Cost Controls

• Use gemini-2.0-flash for high-volume sub-agent calls
• Context caching for repeated prompts (up to 75% savings)
• max_output_tokens=2048 for most tasks
• Monitor: aiplatform.googleapis.com/prediction/online/token_count

5. RAG Engine Cost Controls

• Delete stale documents from corpus
• Batch embedding for initial ingestion
• top_k=5 (not higher)
• Archive cold corpora to Cloud Storage lower tier

6. Memory Bank Cost Controls

• TTL: 7 days for short-lived session memories
• Firestore-backed for most use cases
• Index only user_id and session_id

7. Networking Cost Controls

• Private Google Access to avoid Vertex AI egress charges
• VPC routing for all agent traffic
• Cloud NAT only where unavoidable

8. Storage Lifecycle

{
  "rule": [{
    "action": { "type": "Delete" },
    "condition": { "age": 7 }
  }]
}

Apply with: gcloud storage buckets update gs://BUCKET --lifecycle-file=lifecycle.json

9. End-of-Day Teardown Checklist

• Run 03-teardown.sh
• Verify no active Agent Runtimes: gcloud ai agent-engines list --region=us-central1
• Verify no active Vertex AI endpoints: gcloud ai endpoints list --region=us-central1
• Check billing dashboard for anomalies
