Systems and methods for extensible distributed configuration management of computer resources are described. Examples include a computer system including a processing unit and a storage device that stores a model definition and one or more asset plug-ins (each of the one or more asset plug-ins configured to expose at least one asset object that represents a computer resource). The computer system further includes memory that stores an asset model created based at least in part on the model definition, and a network interface configured to deploy to at least one managed system a compatible asset plug-in (the model definition including at least one conditional reference to the compatible asset plug-in). If a condition specified within the asset model is satisfied the processing unit selects the compatible asset plug-in for deployment, the condition being defined within the model definition and designated as applicable to the at least one conditional reference.
