Case Study: Booking.com achieves scalable, reliable load balancing with HAProxy Enterprise

Booking.com handles billions of requests per day with HAProxy

Booking.com, a global leader in online travel, faced challenges with its outdated and manually intensive load-balancing infrastructure. Their previous F5 hardware solution was difficult to automate, scale, and upgrade, creating a bottleneck as the company grew. This led them to seek a software-based approach to improve performance and manageability, partnering with HAProxy.

The solution involved implementing a custom Load-Balancer-as-a-Service platform powered by HAProxy Enterprise. This provided unprecedented visibility through a custom API and enabled smart traffic routing with Anycast. The results gave Booking.com's team the ability to scale, visualize, and route traffic in new ways, handling billions of requests per day with improved reliability and automated failover protection.
