These services need to be fast, reliable and highly scalable as they have a huge impact on the day-to-day experience of every Roblox user. In addition, the team owns shared libraries, infrastructure microservices, and the web infrastructure used by all other Roblox full-stack feature teams. We ship with testable and configurable features that allow for rapid experimentation, data collection, and optimize for performance and user engagement. From serving basic user information to populating content into in-experience. Core Services is integral to the Roblox experience.
