Event-driven Architecture and REST Architectural Style: An Exploratory Study on Modularity


 Event-driven architecture has been widely adopted in the software industry, emerging as an alternative to development of enterprise applications based on REST architectural style. However, little is known about effects event-driven modularity while evolve. Consequently, practitioners end up adopting it without any empirical evidence its impacts essential indicators, including separation concerns, coupling, cohesion, complexity, and size. This article, therefore, reports exploratory study comparing style terms modularity. A realistic application was developed using through ve evolution scenarios. In each scenario, a feature added. The generated versions were compared ten metrics. initial results suggest that improved but outperformed considering metrics complexity findings are encouraging can be seen first step more ambitious agenda empirically evaluate bene ts against style.
