Three production deployment strategies
- ⏱️ Setup: 5 minutes
- 💰 Cost: Free tier + pay-as-you-go
- 📊 Scaling: Automatic
- Best for: Rapid deployment, zero infrastructure management
- ⏱️ Setup: 15 minutes
- 💰 Cost: ~$10-50/month (infrastructure only)
- 📊 Scaling: Manual/Kubernetes
- Best for: Full control, on-premises, private cloud
- ⏱️ Setup: 30 minutes
- 💰 Cost: ~$5-25/month (pay-per-use)
- 📊 Scaling: 0 to 1000+ instances automatically
- Best for: Variable workloads, global deployment
Tech: Smithery, Docker, Cloud Run, FastAPI, GCP Secret Manager
Test Results:
- ✅ Smithery: 5/5 tests passed (3.04s)
- ✅ Docker: 6/6 tests passed (50ms avg)
