Production Deployment Patterns

Pattern 1: Anycast Service Announcement

Common at: Facebook, Dailymotion, OpenDNS, BBC

Architecture:

┌─────────────┐
│ Service(s)  │
│ + Health    │
│   Check     │
└──────┬──────┘
       │
       v
  ┌─────────┐      BGP      ┌─────────┐
  │ ExaBGP  │────────────────│ Router  │
  └─────────┘   Announce    └─────────┘
                10.0.0.1/32
                when healthy

Use Cases:

• Load balancer VIPs
• DNS resolvers
• API endpoints
• DHCP servers

Pattern 2: FlowSpec DDoS Mitigation

Common at: Cloudflare, Oracle Dyn

Architecture:

┌──────────────┐
│ DDoS         │
│ Detection    │
└──────┬───────┘
       │ Attack detected
       v
  ┌─────────┐   FlowSpec   ┌─────────┐
  │ ExaBGP  │──────────────│ Router  │
  └─────────┘   Rules      └─────────┘
                            │
                            v
                        Drop/Rate-limit
                        attack traffic

Use Cases:

• Automated DDoS mitigation
• Traffic filtering
• Rate limiting

Pattern 3: Container/Kubernetes Routing

Common at: Dailymotion, Blablacar

Architecture:

┌─────────────────────┐
│ Kubernetes          │
│ ┌─────┐  ┌─────┐   │
│ │ Pod │  │ Pod │   │
│ └─────┘  └─────┘   │
│   10.1.1.1  10.1.1.2│
└──────────┬──────────┘
           │
      ┌────────────┐
      │  ExaBGP    │
      │  Watcher   │
      └─────┬──────┘
            │ Announce /32
            v
       ┌─────────┐
       │ Router  │
       └─────────┘

Use Cases:

• Direct pod routing
• Service mesh integration
• Multi-datacenter Kubernetes

Pattern 4: ECMP Load Balancing

Common at: Facebook (Katran), Microsoft

Architecture:

Multiple ExaBGP instances announce same prefix:

ExaBGP-1 ──┐
ExaBGP-2 ──┼─> Announce 10.0.0.1/32 ─> Router (ECMP)
ExaBGP-3 ──┘

Router spreads traffic across all paths

Use Cases:

• Layer 4 load balancing
• Geographic distribution
• Capacity scaling
