Abstract: Operating a microservices registry hub that automatically discovers and sorts services. A microservice architecture application includes a plurality of services, the plurality of services are each an application program interface (API) performing a piecemeal function of an overall application function. The microservices registry hub stores an index of the services. The microservices registry hub is configured to enable consumption of services in execution environments. The service hub uses observation agents to monitor particular execution environments and generate a list of unsorted service data associated services available within that environment. That list is automatically pre-sorted based on a predetermined set of heuristic rules based on the index of the plurality of services. An administrator later goes through the pre-sorted service data and confirms whether or not that pre-sorting was correct.
