From a N layers distributed system to oriented service architecture: systematic review

This article performs a systematic review on n-layers distributed systems and service-oriented architectures (SOA). Focusing specifically on answering questions such as: ¿Which are the advantages and disadvantages of implementing both a distributed N-layer system and an SOA architecture within a company or organization? ¿What characteristics, structures and components are considered elementary in n-layers distributed systems and SOA architectures? Which are the general requirements that are taken into consideration when wanting to migrate to an SOA architecture? Which are the processes and/or models considered when migrating to an SOA architecture? To answer these questions, information between 2011 and 2021 was analyzed, with an MLR (Multivocal Literature Review) methodology, based on SLR (Systematic Literature Review). The results obtained show and describe characteristics, structures and basic components that must exist within both architectures, as well as the establishment of steps, processes, and models to follow for a correct migration towards an SOA architecture.
