Running real-time quizzes for millions of players worldwide puts serious pressure on the backend. In this talk, I’ll walk through how we’ve scaled Kahoot as it grew — from a well-designed monolith that served us reliably, to a gradual transition toward microservices driven purely by scale and evolving needs.
