Pirate Kings`, a free-to-play mobile gaming platform with over 70 million users, was initially hosted by a third-party MongoDB service but faced performance issues and high costs. The game's developer, Jelly Button Games, decided to migrate to `MongoDB Professional` and `Cloud Manager` to better manage its growing user base. With the help of `MongoDB Professional Services`, they successfully upgraded their database in under two months, achieving a 60% cost savings and significant improvements in performance and data protection. The transition brought much-needed confidence to the development team, enabling them to focus on developing new games, with plans for two new titles per year built on MongoDB.
