MOMMIV: Model for the decomposition of a monolithic architecture towards a microservices architecture under the principle of information hiding

Abstract:

The current technological changes and the need for companies to migrate their legacy applications to modern platforms have allowed to find new ways to migrate applications to other architectures such as microservices. However, there are challenges that must be considered in the migration process, such as the complexity of extracting the business logic embedded in the applications, the difficulties due to changes in the relational databases of the application that affect the transactionality of the application, the creation of duplicate microservices or that perform more than one business functionality. Up to the present time, a model has not been found in the literature that allows having a theoretical foundation that solves these problems. This research work collects important aspects of decomposition and migration through a literature review, from which a model that allows the decomposition of monolithic architectures towards microservices is born and exposed based on the Principle of Information Hiding.
