Case Study: Wargaming achieves real-time personalization and 5–10% lift in player lifetime value with Cloudera

Wargaming - Customer Case Study

Wargaming, the Cyprus‑based maker of free‑to‑play MMOs like World of Tanks, serves over 150 million registered players worldwide and relies on in‑game purchases to monetize its freemium model. The business challenge was to capture and analyze massive volumes of gameplay data (about 550 million events/day, ~3TB raw data/day) and act in seconds to personalize offers, improve player experience, and drive lifetime value.

Wargaming built a scalable enterprise data platform using a Cloudera Hadoop “data reservoir” with Oracle data marts, plus a Player Relationship Management Platform that ingests tens of thousands of events per second and uses Kafka, Spark Streaming and machine learning in a real‑time rules engine. The result: personalized, near‑real‑time recommendations and campaigns that lifted lifetime value by 5–10% versus non‑personalized interactions, enabled a tenfold increase in simultaneous campaigns, and supported data‑driven product and marketing decisions.
