Abstract

The modernization of legacy systems to microservice architecture (MSA) has been a subject of interest in both academic and industrial areas. This architectural style has facilitated the development of software systems by composing them as a collection of small and loosely coupled services, each running in its process and communicating with lightweight mechanisms. In parallel, Delphi is an integrated development environment (IDE), based on the Object Pascal programming language, that enables the rapid application development of software for desktop, mobile, web, and console applications. Although the software systems developed in Delphi have considerable relevance in contemporary software, there is a lack of documented processes that facilitate the modernization of legacy systems in Delphi to MSA. This paper presents the Micro4Dephi, a modernization process based on six well-defined activities. Each activity is constituted by a step set, which may vary in number and content, thus allowing such activities to be performed. A case study was conducted to show the applicability of the process proposed in this paper. The results provide important evidence that enables a clear perspective on the process’s contribution to software modernization.
