This document summarizes the results of a systematic literature review on microservices. 37 papers were analyzed to understand the current research trends, practical motivations, and emerging standards around microservices. The majority of research conducted were solution proposals (17 papers) and validation/evaluation research (10 papers). Most papers investigated microservices in the context of software as a service (SaaS) cloud computing models. Cost, performance, scalability, and deployment were common practical motivations studied. Emerging standards and tools discussed included REST, Docker, Kubernetes and service mesh technologies.
