✅ Load Balancer Functionality:

🌍 Geographic Load Balancer Features:

• Purpose: Geographic load balancing for AITBC Marketplace
• Regions: 6 geographic regions configured
• Health Monitoring: Continuous health checks
• Load Distribution: Weighted round-robin routing
• Failover: Automatic failover to healthy regions

📊 Regional Configuration:

{
  "us-east": {"url": "http://127.0.0.1:18000", "weight": 3, "healthy": false},
  "us-west": {"url": "http://127.0.0.1:18001", "weight": 2, "healthy": true},
  "eu-central": {"url": "http://127.0.0.1:8006", "weight": 2, "healthy": true},
  "eu-west": {"url": "http://127.0.0.1:18000", "weight": 1, "healthy": false},
  "ap-southeast": {"url": "http://127.0.0.1:18001", "weight": 2, "healthy": true},
  "ap-northeast": {"url": "http://127.0.0.1:8006", "weight": 1, "healthy": true}
}

---

✅ Testing Results:

🧪 Health Check Results:

# Load Balancer Health Check
curl -s http://localhost:8017/health | jq .status
✅ "healthy"

# Regional Health Status
✅ Healthy Regions: us-west, eu-central, ap-southeast, ap-northeast
❌ Unhealthy Regions: us-east, eu-west

📊 Comprehensive Test Results:

# All Services Test Results
✅ Coordinator API (8000): ok
✅ Exchange API (8001): Not Found (expected)
✅ Blockchain RPC (8003): 0
✅ Multimodal GPU (8010): ok
✅ GPU Multimodal (8011): ok
✅ Modality Optimization (8012): ok
✅ Adaptive Learning (8013): ok
✅ Web UI (8016): ok
✅ Geographic Load Balancer (8017): healthy
