Architecture Overview

Dual-Mode Server

The backend runs in dual-mode:

Flower Aggregator (Port 8080)
- Federated learning coordination
- Stake-weighted aggregation
- Byzantine tolerance (50% fault tolerance)
- gRPC-based node communication
Flask Metrics API (Port 8000)
- Real-time convergence tracking
- Prometheus metrics export
- Health checks
- Performance monitoring

Node Architecture

Each node runs a Flower client that:

Connects to aggregator at backend:8080
Trains local MNIST model
Applies differential privacy (Opacus)
Supports Byzantine mode (inverted updates for testing)
Reports metrics back to aggregator

Prerequisites

Required Software

Docker Desktop 4.0+ (with Docker Compose v2)
8GB+ RAM available
20GB+ disk space
Linux/macOS/Windows (WSL2)

Verify Installation

docker --version          # Docker 24.0+
docker compose version    # Docker Compose 2.0+

Network Requirements

For local testing: localhost only For remote staging/prod: Network connectivity to aggregator host

Local Testing (5 Nodes)

Step 1: Clone & Navigate

cd Sovereign_Map_Federated_Learning

Step 2: Build Images

docker compose -f docker-compose.full.yml build

First-time build: ~5-10 minutes (downloads PyTorch base image) Subsequent builds: ~30 seconds (cached layers)

Step 3: Start System (5 Nodes)

# Start backend + 5 node agents
docker compose -f docker-compose.full.yml up --scale node-agent=5 -d

# View logs
docker compose -f docker-compose.full.yml logs -f backend

# View node logs
docker compose -f docker-compose.full.yml logs -f node-agent

Step 4: Verify Connectivity

# Backend health check
curl http://localhost:8000/health
# Expected: {"status": "healthy", "service": "metrics-api"}

# Check active nodes
curl http://localhost:9090/api/v1/targets | jq '.data.activeTargets'

Step 5: Monitor Convergence

# Get convergence data in real-time
curl http://localhost:8000/convergence | jq .

# Expected output:
# {
#   "rounds": [1, 2, 3, ...],
#   "accuracies": [65.2, 67.8, 70.1, ...],
#   "losses": [3.42, 3.05, 2.71, ...],
#   "current_accuracy": 70.1,
#   "current_round": 3
# }

Step 6: View Dashboards

Grafana: http://localhost:3000 (admin/admin)
- Dashboard: "Sovereign Map - FL Monitoring"
- Watch: Accuracy convergence, loss reduction
Prometheus: http://localhost:9090
- Query: sovereignmap_fl_accuracy (real-time accuracy)

Step 7: Cleanup

docker compose -f docker-compose.full.yml down -v

Staging Deployment (50 Nodes)

Step 1: Configure Environment

Create .env file:

cat > .env << 'EOF'
NUM_NODES=50
BYZANTINE_NODES=2
FLASK_ENV=production
PROMETHEUS_PORT=9090
GRAFANA_PORT=3000
EOF

Step 2: Start with 50 Nodes

docker compose -f docker-compose.full.yml up --scale node-agent=50 -d

Expected startup time: 30-60 seconds Memory usage: ~4-6GB CPU usage: 2-4 cores

Step 3: Verify All Nodes Connected

# Check Prometheus targets
curl -s http://localhost:9090/api/v1/targets?state=active | jq '.data.activeTargets | length'

# Should show 50+ active targets

Step 4: Test Byzantine Tolerance

Run 2 Byzantine nodes:

# Start nodes with Byzantine flag
docker compose -f docker-compose.full.yml up \
  --scale node-agent=48 \
  -e BYZANTINE=true \
  -d

Expected behavior:

System continues learning despite 2 Byzantine nodes
Accuracy still converges (slower but stable)
See metrics for impact analysis

Step 5: Load Test

Generate continuous load:

# Run 100 FL rounds continuously
for i in {1..100}; do
  curl -s http://localhost:8000/convergence | jq '.current_accuracy'
  sleep 30
done

Step 6: Monitor Performance

# Check memory usage
docker stats sovereign-backend --no-stream

# Check aggregator response time
time curl http://localhost:8000/metrics_summary

# View latency metrics
curl -s http://localhost:9090/api/v1/query?query=sovereignmap_fl_round_duration_seconds | jq '.data.result'

Production Deployment (100+ Nodes)

Prerequisites for Production

Dedicated server: 16GB+ RAM, 8+ CPU cores
Fixed IP address (for node connections)
Docker Swarm or Kubernetes (optional but recommended)
SSL/TLS certificates (for mTLS node communication)
Persistent volumes for metrics storage

Step 1: Prepare Infrastructure

# Create data directories for persistence
mkdir -p /var/sovereign-map/{prometheus,grafana,alertmanager}

# Set proper permissions
chmod 755 /var/sovereign-map/*

Step 2: Update Docker Compose for Production

Create docker-compose.prod.yml:

version: '3.9'

services:
  backend:
    image: ghcr.io/rwilliamspbg-ops/sovereign-map-backend:latest
    environment:
      - NUM_ROUNDS=1000
      - MIN_FIT_CLIENTS=100
    volumes:
      - /var/sovereign-map/backend:/app/data
    restart: always
    deploy:
      resources:
        limits:
          cpus: '4'
          memory: 8G

  node-agent:
    image: ghcr.io/rwilliamspbg-ops/sovereign-map-backend:latest
    environment:
      - AGGREGATOR_HOST=backend
      - AGGREGATOR_PORT=8080
    deploy:
      replicas: 100
      resources:
        limits:
          cpus: '0.5'
          memory: 512M

  prometheus:
    volumes:
      - /var/sovereign-map/prometheus:/prometheus
    restart: always

  grafana:
    volumes:
      - /var/sovereign-map/grafana:/var/lib/grafana
    restart: always

volumes:
  prometheus-data:
    driver: local
    driver_opts:
      type: none
      o: bind
      device: /var/sovereign-map/prometheus

Step 3: Deploy 100 Nodes

docker compose -f docker-compose.prod.yml up --scale node-agent=100 -d

# Verify all nodes connected
sleep 60
curl http://localhost:8000/convergence | jq '.current_round'

Step 4: Enable Monitoring & Alerts

# Set up alert notifications (email/Slack)
curl -X PUT http://localhost:9093/api/v1/alerts \
  -H "Content-Type: application/json" \
  -d '{"groupBy": ["alertname"], "receiver": "slack"}'

Step 5: Setup Auto-Scaling (Optional with Kubernetes)

# Create Kubernetes deployment (if using K8s)
kubectl apply -f - << 'EOF'
apiVersion: apps/v1
kind: Deployment
metadata:
  name: sovereign-map-node
spec:
  replicas: 100
  selector:
    matchLabels:
      app: node-agent
  template:
    metadata:
      labels:
        app: node-agent
    spec:
      containers:
      - name: node-agent
        image: ghcr.io/rwilliamspbg-ops/sovereign-map-backend:latest
        env:
        - name: AGGREGATOR_HOST
          value: backend
        - name: NODE_ID
          valueFrom:
            fieldRef:
              fieldPath: metadata.name
        resources:
          requests:
            memory: "256Mi"
            cpu: "250m"
          limits:
            memory: "512Mi"
            cpu: "500m"
EOF

Prometheus Queries

# Average accuracy across all rounds
avg(sovereignmap_fl_accuracy)

# FL round duration p95
histogram_quantile(0.95, sovereignmap_fl_round_duration_seconds)

# Node participation rate
count(sovereignmap_active_nodes) / 100

# Byzantine impact (accuracy delta)
rate(sovereignmap_fl_accuracy[5m])

Health Checks

# Backend health
curl -s http://localhost:8000/health | jq '.status'

# Prometheus health
curl -s http://localhost:9090/-/healthy

# Grafana health
curl -s http://localhost:3000/api/health | jq '.status'

# Count connected nodes (from Prometheus)
curl -s http://localhost:9090/api/v1/targets?state=active | jq '.data.activeTargets | length'

Troubleshooting

Issue: Nodes Can't Connect to Aggregator

Symptom: Nodes repeatedly try to connect but fail

Solution:

# Verify backend is running
docker ps | grep sovereign-backend

# Check Flower server is listening on 8080
docker exec sovereign-backend ss -tuln | grep 8080

# Check network connectivity from node
docker exec <node-container> curl -v backend:8080

Issue: FL Rounds Not Progressing

Symptom: current_round stays at 0

Solution:

# Check backend logs
docker logs sovereign-backend | grep "FL Round"

# Verify min_fit_clients setting
# Edit docker-compose.yml: MIN_FIT_CLIENTS should be <= active nodes

# Restart backend
docker restart sovereign-backend

Issue: Out of Memory

Symptom: Containers killed with OOMKilled

Solution:

# Reduce node scale
docker compose -f docker-compose.full.yml up --scale node-agent=10

# Or increase system memory limits
docker update --memory 16g sovereign-backend
docker update --memory 1g node-agent

Issue: Accuracy Not Converging

Symptom: Accuracy stays flat or oscillates wildly

Solution:

# Check for too many Byzantine nodes (>50%)
curl http://localhost:8000/convergence | jq '.round_participants'

# Reduce Byzantine ratio
docker compose -f docker-compose.full.yml up --scale node-agent=100 -d

# Monitor convergence for 10+ rounds
for i in {1..10}; do
  sleep 60
  curl http://localhost:8000/convergence | jq '{round: .current_round, accuracy: .current_accuracy}'
done

Issue: Docker Build Fails

Symptom: PyTorch dependency timeout

Solution:

# Use pre-built image (skip build)
docker pull pytorch/pytorch:2.1.0-runtime-slim

# Or build with timeout
docker compose -f docker-compose.full.yml build --no-cache --progress=plain

# Or build specific stage
docker buildx build --target builder -t sovereign-test:builder . --load
