Det mindre i det störres tjänst : En studie om mikrotjänster i systemutveckling

Microservices is perhaps the latest addition to the list of buzzwords in software engineering. And since 2014 the research on the subject been constantly growing. In this paper I conduct a comparative literature overview over microservices. Based on the findings and analysis of the overview, I propose a model called the microservices-triad for a better understanding what microservices are, and how it relates to other techniques in software engineering. The three legs of the triad are the following, 1) A style of designing one small service, 2) The system administrative approach, where DevOps, CI/CD and distributed computer system dictates what kind of application one build, and lastly, 3) Microservices as a new form of architectural design. Furthermore, I’ve migrated – a part of – one monolithic IoT-application into using a microservice. This migration is also benchmarked to see if the performance is better with the new, re-designed IoT-application
