Cloud services offer several benefits from the customers perspective, such as scalable resources, continuous updates, and flexible licensing. Although companies leverage cloud services in many of their operations, the most mission-critical systems in their core business are still typically on-premise systems. The topic of this thesis is in companies' experiences of software-as-a-service model cloud services, as well as views on moving business-critical systems to the cloud.\n\nThe thesis introduces the topic with an extensive literature review that explores traditional on-premise systems, different forms of cloud services, and the transition to cloud services. The empirical part has been carried out by interviewing representatives of six companies. All interviewees had extensive experience with the needs of business-critical systems, as well as experience with the use of modern cloud services in corporate support functions. The results of the thesis reflected the varying needs and experiences of companies with cloud services. The results provided indications that companies are not yet ready to move their core systems to the cloud. The degree of cloud maturity was not yet seen as sufficient for business-critical applications.", "language": "en", "element": "description", "qualifier": "abstract", "schema": "dc"}, {"key": "dc.description.provenance", "value": "Submitted by Paivi Vuorio (paelvuor@jyu.fi) on 2020-06-05T08:07:53Z\nNo. of bitstreams: 0", "language": "en", "element": "description", "qualifier": "provenance", "schema": "dc"}, {"key": "dc.description.provenance", "value": "Made available in DSpace on 2020-06-05T08:07:53Z (GMT).
