Load Balancer Setup Service

We recommend the load balancer that fits your architecture. HAProxy for high-throughput TCP and HTTP workloads with advanced routing rules. Nginx for applications that also need reverse proxy, caching, and static file serving. Traefik for container-native environments with automatic service discovery from Docker or Kubernetes labels.

The load balancer architecture accounts for high availability from the start. Primary and standby load balancers share a virtual IP address via keepalived. If the primary fails, the standby takes over in under a second with no client-visible disruption. DNS-level failover provides an additional layer of redundancy for multi-datacenter deployments.

We configure traffic distribution algorithms based on your application behavior. Round-robin for stateless services, least-connections for workloads with variable request duration, and IP-hash for session affinity when your application requires it. Weighted distribution enables gradual traffic shifting during deployments or A/B testing.

Health checks verify backend server availability every few seconds. HTTP health checks probe your application's health endpoint and verify response codes and body content. Failed backends are removed from rotation immediately and re-added only after passing consecutive health checks. This prevents users from being routed to a crashing server.

The load balancer handles SSL/TLS termination, offloading encryption work from your application servers. We configure modern TLS settings — TLS 1.2 and 1.3 only, strong cipher suites, HSTS headers, OCSP stapling, and certificate transparency monitoring. SSL Labs scores of A+ are standard.

HTTP/2 is enabled for improved multiplexing and header compression. WebSocket connections are proxied transparently. gzip and Brotli compression reduce bandwidth usage. Rate limiting and connection throttling protect your application from traffic spikes and abuse. The load balancer becomes your application's front door with enterprise-grade security and performance features.

Load balancers enable zero-downtime deployments by managing traffic during application updates. We configure deployment integration so your CI/CD pipeline drains connections from the server being updated, waits for in-flight requests to complete, deploys the new version, runs health checks, and restores traffic. Users never see a 502 error during deployment.

Blue-green and canary deployment strategies are implemented at the load balancer layer. Blue-green switches traffic atomically between two backend groups. Canary routes a percentage of traffic to the new version and monitors error rates before promoting. Both strategies provide instant rollback capability by reverting the traffic routing.
