Method and system to identify and prioritize re-factoring to improve micro-service identification

A computer system wherein there is a genetic manager to apply a genetic algorithm to parent re-factoring operations selected from an initial identified set of such operations for source code to produce an offspring population of the operations as a subset of the parent re-factoring operations. A score manager measures a fitness score of each re-factoring operation including collecting runtime traces of the source code and applies the traces to the subset such that a classifier can prioritise operations within the subset based on a corresponding fitness score. Responsive to the prioritisation one or more of the re-factoring operations can be applied to the source code to produce one or more micro-service candidates. A crossover operator may be applied to generate a combination of offspring re-factoring operations, and a mutation operator may be applied to introduce variability to the generated combination. The application of the genetic algorithm and fitness score measurement may be an iterative ...
