Case Study: Dream11 achieves 30,000 user joins per second with Akka

Dream11 scales to 30,000 joins per second with Akka

Dream11, India's largest sports entertainment streaming platform, faced a critical challenge with its failing contest infrastructure. The platform, experiencing explosive growth to over 250 million users, could not handle traffic spikes of tens of thousands of users per second attempting to join contests before major sporting events, leading to widespread registration failures and contest cancellations. With a strict deadline before the Indian Premier League season, they turned to the Akka platform for a solution.

By implementing Akka, Dream11 replaced its legacy system with a reactive architecture that delivered elastic scalability and resilience. The results were significant: the new system achieved 30,000 user joins per second at 150ms latency, launched a full month ahead of schedule, and reduced cloud infrastructure costs by 30%. This allowed Dream11 to reliably serve its massive user base through India's highest-traffic sporting events with zero infrastructure-related contest cancellations.
