Värt mödan? : En litteraturstudie om migrationer av legacyapplikationer till molnet

Sammanfattning: Abstract This paper is a thesis work during the Computer Science Bachelor programme at Malmö University spring 2022. The thesis conducts a litterature review on benefits and risks of legacy applications to cloud. What are the challenges of migrating legacy applications to cloud? Why do businesses migrate legacy applications to cloud in relation to the challenges presented in the litterature? The thesis reviews ten research articles and a number of books in order to answer and discuss the questions. It concludes that in spite of a great number of challenges presented in the litterature, both technical and operational, businesses still see the benefits of legacy application migration and perform the back breaking technical migrations of monolithic architecures in legacy applications, to modern, fast-deploying microservices. This in order to achieve cost reductions, fast deployments and reduced maintenance in software over time.
