Design and Implementation of Microservices System Based on Domain-Driven Design

Abstract

PT. XYZ as an IT company has developed a basic product system for e-procurement applications to meet the needs of automation in the internal procurement process of a company. The e-procurement application system developed by PT. XYZ is designed using a monolithic architecture where the application is wrapped in a large package and dependencies between modules. The modules are an integrated whole process. If there is a change or enhancement to one particular module that is made to adjust the business process, then this will have an impact on the functionality of the other modules. Therefore it is necessary to consider other architectural alternatives so that in the future the e-procurement application system is more adaptive to change. So, it can face problems that arise with old architecture. We proposed the design the transformation process using microservices architecture. We use Domain-Driven Design (DDD) approach. The results showed that the microservices architecture design can produce a system that is more adaptive to a change in which the module is designed to stand alone.
