A Component-Based Evolution Model for Service-Based Software Architectures

摘要

Microservices architecture has emerged as an architectural style which focuses on the design and development of software systems as a set of small independent services. Although MSA is inspired by the Service-Oriented Architecture style (both are service-based architectures), it presents important differences. Likewise, software architecture must evolve as new architectural styles and software frameworks arise, and the evolution of the software architecture is considered as a central feature of any software system. In this way, this paper proposes an approach to evolve SOA to MSA architectures through the use of Sarch language. To accomplish this, the language was extended to allow the modeling of the two architectural styles from the component-and-connector view, the inclusion of a decomposition view for functional properties, and the use of a model-to-model transformation algorithm.
