Load Balancing

Load Balancers

• Traffic Cops: Spread incoming requests across multiple servers, preventing any single server from being overwhelmed.
• Types:
  • Network Load Balancers (Layer 4): Route based on IP/port, good for raw speed.
  • Application Load Balancers (Layer 7): Aware of HTTP requests, making smart routing decisions on paths or content.
• Importance:
  • Scaling: Add more servers behind the load balancer as traffic grows.
  • Availability: If a server fails, the load balancer redirects its traffic.
