Automatic discovery of microservices from monolithic applications

Abstract:

A method, computer program product, and a system to replace monolithic applications with microservices includes a processor(s) obtaining a requirement for the monolithic application. The processor(s) automatically identifies, based on a sentence comprising the requirement, a given component of the monolithic application, based on analyzing the requirement. The processor(s) determines, based on syntax of the sentence, an initial class and a responsibility for the given component. The processor(s) generates a bounded context for the given component, based on analyzing one or more additional sentences comprising the requirement, to identify additional classes beyond the initial class associated with the responsibility in the requirement. The processor(s) identifies, in a microservices architecture executing in a shared computing environment, one or more microservices within the bounded context. The processor(s) generates a stub for use by the user, via the client, for accessing the one or more identified microservices.
