Resource Utilization

• CPU: Efficient Next.js 14.2.31 runtime
• Memory: Well within allocated limits
• Startup Time: 44-48ms average per container
• Health Status: All containers reporting healthy

Network Architecture Validation

Docker Networks

1. tengig (External/Public)

   • Type: Overlay network for external traffic
   • Purpose: Traefik ingress and SSL termination
   • Status: ✅ Operational

2. chorus-website_chorus_website_network (Internal)

   • Type: Stack-specific overlay network
   • Purpose: Internal service communication
   • Status: ✅ Operational with load balancer

Port Configuration

• Internal Container Port: 80/tcp
• External Published Port: 3100/tcp
• Port Mapping: *:3100->80/tcp (ingress mode)
• Protocol: TCP with proper HTTP/HTTPS handling

Connectivity Test Results

Local Port Access (localhost:3100)

• Status: ✅ OPERATIONAL
• Response Time: 8-15ms average
• HTTP Status: 200 OK
• Content: Full Next.js application loading correctly
• Headers: Proper security headers present (X-Frame-Options, X-Content-Type-Options, Referrer-Policy)

External HTTPS Access

Primary Domain (https://www.chorus.services)

• Status: ✅ OPERATIONAL
• Response Time: 69-76ms average
• HTTP Protocol: HTTP/2
• SSL Certificate: Valid (0 = success)
• DNS Resolution: 5-6ms
• TCP Connection: 6-7ms
• SSL Handshake: 43-58ms

Redirect Domain (https://chorus.services)

• Status: ✅ OPERATIONAL
• HTTP Status: 307 Temporary Redirect
• Redirect Target: https://www.chorus.services/
• Redirect Time: <1ms

External IP Access (202.171.184.242:3100)

• Status: ⚠️ BLOCKED (Expected - firewall protection)
• Note: Direct IP access blocked by security configuration (normal for production)

Performance Metrics

Response Time Analysis

Endpoint	Min	Max	Average	Protocol
localhost:3100	8.6ms	14.6ms	10.9ms	HTTP/1.1
www.chorus.services	69.2ms	76.2ms	73.2ms	HTTP/2

Content Delivery Performance

• Compressed Size: 20,464 bytes (87% compression ratio)
• Uncompressed Size: 162,285 bytes
• Transfer Speed: 361KB/s (compressed), 2.5MB/s (uncompressed)
• Compression: Gzip enabled and working efficiently

Caching Configuration

• Cache-Control: s-maxage=31536000, stale-while-revalidate
• ETag: "cjhbuylf93h0q" (consistent across requests)
• Next.js Cache Status: HIT (optimal caching performance)

SSL/TLS Configuration

Certificate Details

• Certificate Authority: Let's Encrypt
• Certificate Resolver: letsencryptresolver
• SSL Verification: ✅ Valid (result code: 0)
• Protocol: TLS with HTTP/2 support
• Security Headers: Properly configured

Traefik Configuration

• Routing Rule: Host(\www.chorus.services`) || Host(`chorus.services`)`
• Entrypoint: web-secured (HTTPS)
• Middleware: chorus-redirect (apex → www redirect)
• Load Balancer: Configured with passhostheader=true

Load Balancing Assessment

Service Discovery

• Replicas: 2 containers distributed across available nodes
• Load Balancer: Docker Swarm ingress with VIP mode
• Health Checks: Container-level health monitoring
• Distribution: Even traffic distribution confirmed

Container Health

All containers show consistent startup patterns:

• Next.js runtime initialization: ~44-48ms
• Network binding: 0.0.0.0:80 (all interfaces)
• Ready state: Achieved within <50ms

Security Validation

HTTP Security Headers

X-Frame-Options: DENY
X-Content-Type-Options: nosniff
Referrer-Policy: strict-origin-when-cross-origin

Network Security

• External IP direct access blocked (appropriate security posture)
• HTTPS-only access enforced through Traefik
• Proper certificate chain validation

Optimization Recommendations

Performance Optimizations

1. Compression Ratio Excellent: 87% compression achieved (20KB vs 162KB)
2. Caching Strategy Optimal: Long-term caching with stale-while-revalidate
3. HTTP/2 Benefits: Protocol upgrade providing multiplexing advantages

Infrastructure Optimizations

1. Memory Allocation: Current 128MiB limit appropriate for Next.js workload
2. Replica Count: 2 replicas providing adequate redundancy for current load
3. Health Check Timing: Container startup time <50ms is excellent

Monitoring Recommendations

1. Response Time Monitoring: Set alerts for >100ms average response time
2. SSL Certificate Monitoring: Monitor certificate expiration (Let's Encrypt 90-day cycle)
3. Cache Hit Ratio: Monitor Next.js cache performance metrics

Minor Issues Identified

1. Next.js Metadata Warnings: Viewport/themeColor metadata should be moved to viewport export
   • Impact: Minimal (development warnings only)
   • Action: Update Next.js metadata configuration

Conclusion

The CHORUS Services website deployment is FULLY OPERATIONAL with excellent performance characteristics:

• ✅ All critical endpoints responding correctly
• ✅ SSL certificates valid and properly configured
• ✅ Load balancing and redundancy working
• ✅ Performance within acceptable ranges (10-75ms)
• ✅ Security headers and HTTPS enforcement active
• ✅ Compression and caching optimized

The infrastructure demonstrates robust engineering with proper Docker Swarm networking, Traefik routing, and Next.js optimization. The deployment meets production-ready standards for availability, performance, and security.

Network Infrastructure Status: VALIDATED ✅
