Scalable variant configuration platform for online systems

A scalable variant configuration platform separates, behind a defined interface, mechanisms for determining configurations based upon provided variants. Information regarding specific factors, or "variants" is provided and a configuration request object is generated through which services can be configured. A schema is utilized to generate an object model that can assign object-oriented properties, such as type information, to the various factors that can influence configuration. The schema is also utilized to generate a sample configuration file, which can aid in the generation of the configuration file that can specify how one or more factors can affect the configuration of the services. The generation of the configuration request object is based upon self-tuning algorithms that can adapt based upon the types of factors that will be utilized for the configuration of the services being provided.
