A Model-Driven Approach to Microservice Software Architecture Establishment

Abstract

In this positional paper we propose a modeldriven approach which addresses challenges related to modeling, development and deployment of software applications that follow the microservice architecture (MSA) design principles. We argue in favor of a model-driven tool which can be used to resolve challenges from the MSA establishment domain by providing a domain-specific language for MSA modeling and code generators for producing: (i) program and configuration code for MSA implementation; and (ii) program procedures for MSA building, packaging and installation. We give a brief description of two approaches to software application development which emerged in the last decade: the monolithic architecture approach and the MSA approach. We focus on challenges related to MSA establishment and argue that our model-driven approach could be suitable for their resolution. We also propose a plan of research activities aimed at improving our approach and which will lead to the final implementation of a model-driven tool to support such an approach

Monolithic vs. Microservice Architecture: A Performance and Scalability Evaluation

“…It is more complex because it has an influence on the application architecture, but can offer scales that far exceed those that are possible with vertical scaling [56]. Horizontal scaling is more common with microservice applications [36], even though a monolith may be also scaled out by running many instances behind a load-balancer [6]. Nevertheless, scaling out a monolithic application may not be so effective because it commonly offers a lot of services -some of them more popular than others.…”

Eficiency of REST and gRPC Realizing Communication Tasks in Microservice-Based Ecosystems

“…Note that, today, microservices have become more and more popular, and find their way to large-scale heterogeneous deployments, such as in the Internet of Things (IoT), Industry 4.0 [3][4][5][6][7] including cyber-physical systems [8][9]. Dedicated methodologies have also been developed for this class of solutions [10]. During preliminary research, the popularity of various communication technologies that can be used in this context was analysed using, among others, Google Trends.…”
