Abstract

The microservices architecture has become mainstream for the development of business applications because it supports the adaptation of scalability to the type of demand, but, most importantly, because it fosters an agile development process based on small teams focused on the product. Therefore, there is the need to migrate the existing monolith systems to microservices. Current approaches to the identification of candidate microservices in a monolith neglect the cost of redesigning the monolith functionality due to the impact of the CAP theorem. In this paper we propose a redesign process, guided by a set of complexity metrics, that allows the software architect to analyse and redesign the monolith functionality given a candidate decomposition. Both, the redesign process and the metrics are evaluated in the context of candidate decompositions of two monolith systems.
