Techniques for implementing an infrastructure orchestration service are described. In certain embodiments, a cloud infrastructure orchestration system (CIOS) is disclosed that generates customized flock configurations for services to be deployed to different regions supported by the CIOS. The CIOS receives generic configuration information describing a set of infrastructure assets associated with a service and identifies first portions of the generic configuration information for deploying the set of infrastructure assets associated with the service that are configurable. The CIOS receives region configuration information for configuring the generic configuration information and updates the generic configuration information based on the region configuration information. The CIOS then transmits the updated configuration information to set of regions managed by the CIOS.
