Cloud computing seems to offer a promising solution to this problem. Researchers would benefit from acquiring the needed IT resources as a service instead of spending their limited budget on owning and maintaining those resources. How could existing scientific applications be easily modified to exploit the benefits of cloud computing?\r\n\r\nThe aim of this study is to identify methods and practices that support light-weight modernization of scientific applications into a cloud service. The study aims to find answers to the following questions: What are the motives of cloud modernization in the case of a scientific application? Which methods and practices support researchers' expectations and objectives? How can the modernization be done in practice?\r\n\r\nThe study starts with a literature review on scientific computing, cloud computing and modernization of legacy applications. Based on the review, a case study is conducted where a scientific application is modernized into a cloud service. Finally, the results combined from the literature review and the case study are used to derive conclusions on the support the observed methods and practices provide for the modernization process from the viewpoint of the researchers wanting to benefit from the advantages of cloud computing with their scientific applications.\r\n\r\nThe study provides a set of findings on the methods and practices that support the cloud modernization of scientific applications.
