-## Current Differences Between Dev and Prod - -### 1. **Replicas** -- **Dev**: 1 replica per service -- **Prod**: 2-3 replicas per service -- **Impact**: Multi-replica issues (race conditions, session handling, etc.) won't be caught in dev - -### 2. **Resource Limits** -- **Dev**: Minimal (64Mi-256Mi RAM, 25m-200m CPU) -- **Prod**: Not explicitly set (uses defaults from base manifests) -- **Impact**: Resource exhaustion issues may appear only in prod - -### 3. **Environment Variables** -- **Dev**: DEBUG=true, LOG_LEVEL=DEBUG, PROFILING_ENABLED=true -- **Prod**: DEBUG=false, LOG_LEVEL=INFO, PROFILING_ENABLED=false -- **Impact**: Different code paths, performance characteristics - -### 4. **CORS Configuration** -- **Dev**: `*` (wildcard, accepts all origins) -- **Prod**: Specific domains only -- **Impact**: CORS issues won't be caught in dev - -### 5. **SSL/TLS** -- **Dev**: HTTP only (ssl-redirect: false) -- **Prod**: HTTPS required (Let's Encrypt) -- **Impact**: SSL-related issues not tested in dev - -### 6. **Image Pull Policy** -- **Dev**: `Never` (uses local images) -- **Prod**: Default (pulls from registry) -- **Impact**: Image versioning issues not caught in dev - -### 7. **Storage Class** -- **Dev**: Uses default Kind storage -- **Prod**: Uses `microk8s-hostpath` -- **Impact**: Storage-related differences - -### 8. **Rate Limiting** -- **Dev**: RATE_LIMIT_ENABLED=false -- **Prod**: RATE_LIMIT_ENABLED=true -- **Impact**: Rate limit logic not tested in dev - -## Recommendations for Dev-Prod Parity - -### ✅ What SHOULD Be Aligned - -1. **Resource Limits Structure** - - Keep dev limits lower, but use same structure - - Use 50% of prod limits in dev - - This catches resource issues early - -2. **Critical Environment Variables** - - Same security settings (password requirements, JWT config) - - Same timeout values - - Same business rules - - Different: DEBUG, LOG_LEVEL (dev needs verbosity) - -3. **Some Replicas for Critical Services** - - Run 2 replicas of gateway, auth in dev - - Catches load balancing and state management issues - - Still saves resources vs prod - -4. **CORS Configuration** - - Use specific origins in dev (localhost, 127.0.0.1) - - Catches CORS issues early - -5. **Rate Limiting** - - Enable in dev with higher limits - - Tests the code path without being restrictive - -### ⚠️ What SHOULD Stay Different - -1. **Debug Settings** - - Keep DEBUG=true in dev (needed for development) - - Keep verbose logging (LOG_LEVEL=DEBUG) - - Keep profiling enabled - -2. **SSL/TLS** - - Optional: Can enable self-signed certs in dev - - But HTTP is simpler for local development - -3. **Image Pull Policy** - - Keep `Never` in dev (faster iteration) - - Local builds are essential for dev workflow - -4. **Replica Counts** - - 1-2 in dev vs 2-3 in prod (balance between parity and resources) - -5. **Monitoring** - - Optional in dev to save resources - - Essential in prod - -## Proposed Changes for Better Dev-Prod Parity - -### Option 1: Conservative (Recommended) -Minimal changes, maximum benefit: - -1. **Increase critical service replicas to 2** - - gateway: 1 → 2 - - auth-service: 1 → 2 - - Tests load balancing, keeps other services at 1 - -2. **Align resource limits structure** - - Use same resource structure as prod - - Set to 50% of prod values - -3. **Fix CORS in dev** - - Use specific origins instead of wildcard - - Better matches prod behavior - -4. **Enable rate limiting with high limits** - - Tests the code path - - Won't interfere with development - -### Option 2: High Parity (More Resources Needed) -Maximum similarity, higher resource usage: - -1. **Match prod replica counts** - - Run 2 replicas of all services - - Requires more RAM (12-16GB) - -2. **Use production resource limits** - - Helps catch OOM issues early - - Requires powerful development machine - -3. **Enable SSL in dev** - - Use self-signed certs - - Matches prod HTTPS behavior - -4. **Enable all production features** - - Monitoring, tracing, etc. - -### Option 3: Hybrid (Best Balance) -Balance between parity and development speed: - -1. **2 replicas for stateful/critical services** - - gateway, auth, tenant, orders: 2 replicas - - Others: 1 replica - -2. **Resource limits at 60% of prod** - - Catches issues without being restrictive - -3. **Production-like configuration** - - Same CORS policy (with dev domains) - - Rate limiting enabled (higher limits) - - Same security settings - -4. **Keep dev-friendly features** - - DEBUG=true - - Verbose logging - - Hot reload - - HTTP (no SSL) - -## Impact Analysis - -### Resource Usage Comparison - -**Current Dev Setup:** -- ~20 pods running -- ~2-3GB RAM -- ~1-2 CPU cores - -**Option 1 (Conservative):** -- ~22 pods (2 extra replicas) -- ~3-4GB RAM (+30%) -- ~1.5-2.5 CPU cores - -**Option 2 (High Parity):** -- ~40 pods (double) -- ~8-10GB RAM (+200%) -- ~4-5 CPU cores - -**Option 3 (Hybrid):** -- ~28 pods -- ~5-6GB RAM (+100%) -- ~2-3 CPU cores - -### Benefits of Increased Parity - -1. **Catch Multi-Instance Issues** - - Race conditions - - Distributed locks - - Session management - - Load balancing problems - -2. **Resource Issues Found Early** - - Memory leaks - - OOM errors - - CPU bottlenecks - -3. **Configuration Validation** - - CORS issues - - Rate limiting bugs - - Security misconfigurations - -4. **Deployment Confidence** - - Fewer surprises in production - - Better testing - - Reduced rollbacks - -### Tradeoffs - -**Pros:** -- ✅ Catches more issues before production -- ✅ More realistic testing environment -- ✅ Better confidence in deployments -- ✅ Team learns production behavior - -**Cons:** -- ❌ Higher resource requirements -- ❌ Slower startup times -- ❌ More complex troubleshooting -- ❌ Longer rebuild cycles - -## Implementation Guide - -If you want to proceed with **Option 1 (Conservative)**, I can: - -1. Update dev kustomization to run 2 replicas of critical services -2. Add resource limits that mirror prod structure (at 50%) -3. Fix CORS to use specific origins -4. Enable rate limiting with dev-friendly limits -5.

Our total requests (~22.8 GB) fit in 20 GB because: - - Not all services will run at their request levels simultaneously during pilot - - HPA-enabled services (orders, forecasting, notification) start at 1 replica - - Some overhead included in our calculations - -2. **Actual Usage**: Production limits are safety margins. Real usage for 10 tenants will be: - - Most services use 40-60% of their limits under normal load - - Pilot traffic is significantly lower than peak design capacity - -3. **Cost-Effective Pilot**: Starting with 20 GB allows: - - Room for monitoring and logging - - Comfortable headroom (15-25%) - - Easy vertical scaling if needed - -### CPU Calculation Details -- Application services: 5.7 cores requests / 28.5 cores limits -- Databases: 1.8 cores requests / 9 cores limits -- Infrastructure: 0.3 cores requests / 1.5 cores limits -- Gateway/Frontend: 0.8 cores requests / 2.5 cores limits -- Monitoring: 0.7 cores requests / 1.4 cores limits -- **Total requests**: ~9.3 cores -- **Total limits**: ~42.9 cores - -### Storage Calculation -- Databases: 36 GB (18 × 2Gi) -- Model storage: 10 GB -- Infrastructure (Redis, RabbitMQ): 3 GB -- Monitoring: 25 GB -- OS and container images: ~30 GB -- Growth buffer: ~95 GB -- **Total**: ~199 GB → **200 GB NVMe recommended** - ---- - -## Scaling Considerations - -### Horizontal Pod Autoscaling (HPA) - -Already configured for: -1. **orders-service**: 1-3 replicas based on CPU (70%) and memory (80%) -2. **forecasting-service**: 1-3 replicas based on CPU (70%) and memory (75%) -3. **notification-service**: 1-3 replicas based on CPU (70%) and memory (80%) - -These services will automatically scale up under load without manual intervention. - -### Growth Path for 6-12 Months - -If tenant count grows beyond 10: - -| Tenants | RAM | CPU | Storage | -|---------|-----|-----|---------| -| 10 | 20 GB | 8 cores | 200 GB | -| 25 | 32 GB | 12 cores | 300 GB | -| 50 | 48 GB | 16 cores | 500 GB | -| 100+ | Consider Kubernetes cluster with multiple nodes | - -### Vertical Scaling - -If you hit resource limits before adding more tenants: -1. Upgrade RAM first (most common bottleneck) -2. Then CPU if services show high utilization -3. Storage can be expanded independently - ---- - -## Cost Optimization Strategies - -### For Pilot Phase (Months 1-6) - -1. **Disable Nominatim**: Use external geocoding API - - Saves: 70 GB storage, 2 GB RAM, 1 CPU core - - Cost: ~$5-10/month for external API (Google Maps, Mapbox) - - **Recommendation**: Enable Nominatim only if >50 tenants - -2. **Start Without Monitoring**: Add later if needed - - Saves: 25 GB storage, 1.5 GB RAM, 0.7 CPU cores - - **Not recommended** - monitoring is crucial for production - -3. **Reduce Database Replicas**: Keep at 1 per service - - Already configured in base - - **Acceptable risk** for pilot phase - -### After Pilot Success (Months 6+) - -1. **Enable full HA**: Increase database replicas to 2 -2. **Add Nominatim**: If external API costs exceed $20/month -3. **Upgrade VPS**: To 32 GB RAM / 12 cores for 25+ tenants - ---- - -## Network and Additional Requirements - -### Bandwidth -- Estimated: 2-5 TB/month for 10 tenants -- Includes: API traffic, frontend assets, image uploads, reports - -### Backup Strategy -- Database backups: ~10 GB/day (compressed) -- Retention: 30 days -- Additional storage: 300 GB for backups (separate volume recommended) - -### Domain & SSL -- 1 domain: `yourdomain.com` -- SSL: Let's Encrypt (free) or wildcard certificate -- Ingress controller: nginx (included in stack) - ---- - -## Deployment Checklist - -### Pre-Deployment -- [ ] VPS provisioned with 20 GB RAM, 8 cores, 200 GB NVMe -- [ ] Docker and Kubernetes (k3s or similar) installed -- [ ] Domain DNS configured -- [ ] SSL certificates ready - -### Initial Deployment -- [ ] Deploy with `skaffold run -p prod` -- [ ] Verify all pods running: `kubectl get pods -n bakery-ia` -- [ ] Check PVC status: `kubectl get pvc -n bakery-ia` -- [ ] Access frontend and test login - -### Post-Deployment Monitoring -- [ ] Set up external monitoring (UptimeRobot, Pingdom) -- [ ] Configure backup schedule -- [ ] Test database backups and restore -- [ ] Load test with simulated tenant traffic - ---- - -## Support and Scaling - -### When to Scale Up - -Monitor these metrics: -1. **RAM usage consistently >80%** → Upgrade RAM -2. **CPU usage consistently >70%** → Upgrade CPU -3. **Storage >150 GB used** → Upgrade storage -4. **Response times >2 seconds** → Add replicas or upgrade VPS - -### Emergency Scaling - -If you hit limits suddenly: -1. Scale down non-critical services temporarily -2. Disable monitoring temporarily (not recommended for >1 hour) -3. Increase VPS resources (clouding.io allows live upgrades) -4. Review and optimize resource-heavy queries - ---- - -## Conclusion - -The recommended **20 GB RAM / 8 vCPU / 200 GB NVMe** configuration provides: - -✅ Comfortable headroom for 10-tenant pilot -✅ Full monitoring and observability -✅ High availability for critical services -✅ Room for traffic spikes (2-3x baseline) -✅ Cost-effective starting point -✅ Easy scaling path as you grow - -**Total estimated compute cost**: €40-80/month (check clouding.io current pricing) -**Additional costs**: Domain (~€15/year), external APIs (~€10/month), backups (~€10/month) - -**Next steps**: -1. Provision VPS at clouding.io -2. Follow deployment guide in `/docs/DEPLOYMENT.md` -3. Monitor resource usage for first 2 weeks -4.
