Case Study: Betfair achieves high reliability and scalability with Citrix NetScaler ADC

Betfair finds best odds for system reliability and scalability with NetScaler ADC

Betfair, the world’s largest online betting exchange with millions of users and millions of daily transactions, needed to guarantee ultra-fast, highly available transaction processing—especially during massive traffic spikes (up to tens of thousands of HTTP requests per second) and events where even a few milliseconds of delay matter. The core challenge was maintaining consistent, reliable service and rapid response times under extreme load and protecting customer data from threats.

Betfair deployed Citrix NetScaler ADC (40 MPX appliances plus VPX for testing) to provide global server load balancing, application acceleration, data compression, health-based routing and security. The solution scaled smoothly with a pay-as-you-grow model, absorbed peak events like the Grand National without service degradation, accelerated applications (up to 5x), reduced bandwidth and avoided network upgrades, and improved failover and DDoS resilience—delivering a consistently fast, reliable customer experience.
