An apparatus comprises at least one processing device configured to register two or more source services, wherein registering a given source service comprises executing the given source service to identify inputs and outputs of the given source service, and to select a set of outputs from the registered source services for generating at least a portion of a user interface of an application in an application client, the selected set of outputs comprising at least first and second output from first and second ones of the registered source services. The processing device is also configured to determine an orchestration of the registered source services for obtaining the selected set of outputs, to generate a custom microservice configured to execute the registered source services in accordance with the determined orchestration, and to deploy the custom microservice in an auto-scalable computing framework accessible to the application client of the application.
