This thesis presents the essential characteristics of cloud computing such as on-demand self-service, broadband access, resource pooling, rapid elasticity and the measured ser-vice. The study also discusses service delivery models and deployment models, which define how services are delivered to the customer. Cloud computing has security issues just like every computing technology. Because these security problems lie in data transfer and software interfaces, as well as data which has been stored and user access control, they are analyzed in this study. This thesis presents technologies which enable cloud computing such as virtualization and hypervisors that are used to virtualize the servers and which can be used to deploy the services. This thesis was made for a large international IT-company as a part of a customer project. The study presents company products that were used in the project to deliver cost-efficient customer solutions. Cloud computing is a relatively new trend in modern information tech-nology, especially in the constantly evolving Finnish market. This study compares global benefits acquired with cloud computing as well as the effects of this technology to the qual-ity of service and costs. Technologies compared in this study are hypervisors used in
