Project Metamorphosis : dévoilement de la plateforme de streaming d'événements nouvelle génération. En savoir plus


Au service de millions de joueurs dans le monde avec des pipelines de données en temps réel

Demonware, a fully owned subsidiary of Activision Blizzard, designs, develops and hosts online services powering some of the most popular game franchises in the world, including Call of Duty and Skylanders. Alongside the core offerings of match-making, the services include transactions, leaderboards, data pipelines and identity management, among others for millions of users around the world.

Demonware deployed Confluent Platform and Apache Kafka® to scale their data pipeline infrastructure depending on usage as they capture and process the various types of data coming in every second from user activity. The data is sent to various teams within Demonware and Activision who use it to power the various services including diagnostics and optimizing and improving player experiences, which enables designers to adjust and make improvements in the games.

Chef d'équipe, pipelines de données

Grâce à notre pipeline de données soutenue par Kafka, nous sommes en mesure d'assister nos partenaires qui créent chaque année plus de services, plus de fonctionnalités, plus d'instrumentation de données, ainsi que des données encore plus granulaires que l'année précédente.

Powering Call of Duty, Skylanders and Many More

Ultimately, Demonware chose Kafka because is the most mature streaming solution on the market, and the team believes in the power of open source technology. Kafka enables Demonware to scale, and their peak so far has been about one-and-a-half terabytes a day of data with about 3 billion messages per day.

In addition, with a real-time data pipeline, the analysts are able to produce reports and do in-depth analysis on player experience and system diagnostics. This data is then sent back to the designers to improve the game experience and allows them to validate or invalidate their hunches on weapons, level layouts, game modes, etc., ensuring players are having the intended experience when the game is released. The data also powers Analytic Services, an internal services team at Activision Publishing, to infer insights from the raw data to share with game developers.

Everywhere the process of designing and hosting games is becoming a lot more data-driven than it has been in the past. There’s millions of different kinds of instrumentation points that they collect. And that number just keeps growing. “With Kafka, there's always more services. There's always more features. There's always more instrumentation. You can always look at existing features one level deeper than you did the year before,” said Szymanski.
