Case Study: Dream11 achieves 30,000 user-joins/sec scalability and 30% cloud cost savings with the Akka Platform

Scaling Handles Massive Traffic Spikes With Ease

Dream11, India’s largest fantasy‑sports platform, grew from 1 million users in 2014 to over 80 million by 2019 and runs contests tied to real‑world matches that can attract millions of participants in the hour before kickoff. The original architecture couldn’t handle tens of thousands of concurrent join requests per second, causing registration failures, contest oversubscription risks, and threatened revenue just weeks before the Indian Premier League season.

Dream11 adopted a Reactive Architecture using the Akka Platform with support from Embedded Lightbend Engineers and Lightbend Telemetry to build self‑healing, elastic microservices. The new Contest Join app launched a month early, hit over 30,000 joins/sec at ~150 ms latency within a week, cut cloud infrastructure costs by 30%, and delivered the scalable, resilient experience needed for future growth.
