ESL Gaming, the world's largest eSports network has supported the most popular video games with high-profile, branded international leagues and tournaments for more than 20 years. Its ESL Play service has more than 11 million members and has given out more than €7million in prizes. The ESL Gaming team wanted to move critical applications that supported the company’s user services and tournaments to the cloud. For ESL, working with DataStax was the obvious choice.
