Event Oriented vs Object Oriented Analysis for Microservice Architecture: An Exploratory Case Study

Abstract

The rapidly developing internet infrastructure together with the advances in software technology has enabled the development of cloud-based modern web applications that are much more responsive, flexible, and reliable compared to traditional monolithic applications. Such modern applications require new software design paradigms and architectures. Microservice-based architecture (MSbA), which aims to create small, isolated, loosely-coupled applications that work in cohesion, becoming widespread as one of these approaches. MSbA allows the developed applications to be deployed and maintained separately, as well as scaled on demand. However, there is no de facto method for the analysis and design of systems for these architectures. In this paper, we compared the usefulness of the object-oriented (OO) and event-oriented (EO) approaches for analyzing and designing MS-based systems. More specifically, we performed an exploratory case study to analyze, design, and implement a software application dealing with the 'application and evaluation process of graduate students at IzTech'. This paper discusses the results of this case study. We observe that the EO approaches have significant advantages with respect to the OO approaches.Keywords-microservices, event-driven process chains, eEPC, event-oriented analysis, cloud 244 2021 47th Euromicro Conference on Software Engineering and Advanced Applications (SEAA)

Effort Prediction for Microservices: A Case Study

“…Özellikle yeni nesil mimarilerin "monolitler"de olduğu gibi veri tabanı ve işlem odaklı yapıdan mikroservis ve benzeri mimarilerde kullanılan daha davranışsal ve olay odaklı yapılara evrilmeleri, özellikle çevik projelerde zaten zorlukları bulunan işlevsel büyüklük ölçümü uygulamayı daha da zorlaştırmıştır [18]- [20].…”
