A system recommends the refactoring of microservices. The system generates a graph of connected nodes including a first node, which represents a first atomic part of code in a microservice in an application, and a second node, which represents a second atomic part of code in the microservice. The system determines a nodes connection score based on any connections between the first node and the second node. If the nodes connection score satisfies a nodes connection threshold, the system determines a relative code size based on comparing a size associated with the first atomic part of code against a size of the microservice. If the relative code size satisfies a code size threshold, the system outputs a recommendation to disconnect the first atomic part of code from the microservice, create another microservice in the application, and connect the first atomic part of code to the other microservice.
