Introduction Cloud Computing, that is providing computer resources as a service, is a technology revolution offering flexible IT usage in a cost efficient and pay-per-use way. As for the evaluation of companies to whether which technology solution to use, it would be necessary to decide whether or not the evaluation of cloud computing would actually differ to the traditional way of IT outsourcing. Problem Discussion Outsourcing IT capabilities are a crucial and inevitable step for enterprises that want to survive in the currently high competitive climate. Until now most of the researches, that has been done so far, only consider the XaaS model only from a traditional IT outsourcing point of view rather than in the cloud computing context. This research will now include the evaluation of cloud solutions giving companies another possibility to outsource their IT resources. Purpose The purpose is now to see how the evaluation of cloud computing possibilities as an outsourcing option actually differs to traditional IT outsourcing. One aspect that needs to be covered with this purpose, is whether it is possible to evaluate the source through a cloud computing solution with the same concepts and theories used to evaluate traditional IT outsourcing. It will also be the purpose to see, which aspects need to be added or removed when considering a cloud computing opportunity compared to the traditional IT outsourcing. Method With help of the theoretical framework, interviews have been launched with three companies to see what their general opinion and knowledge is on the evaluation of cloud computing and its maturity. Questions have been asked openly so that answers could not be directed or manipulated by the authors of the research. Conclusion After challenging the theoretical framework against the data collected, the traditional IT outsourcing theories appeared to be valid also for the evaluation of cloud computing solutions. Some important concepts are added to the evaluation of cloud computing solutions in consequence of particularities present in the model.

This thesis is focused on analyzing the current state of SaaS (Software as a Service) and impact of SaaS on corporate's ICT as a whole. The aim is to explain the concepts and implications of modern forms of providing services, to describe and to evaluate their benefits and risks and to assess future developments in this area. The attention will be paid on specifics of the environment of Czech companies. The first part of this work deals with the current SaaS solutions and related technologies. Emphasis is placed on acquainting the reader with currently available (or introduced by mid-2011) technologies and their mutual relationships. This section also summarizes the current level of knowledge of the field and on this basis provides definitions of areas and technologies. The next part of the thesis focuses on a particular cloud and SaaS solutions available on nowadays market. The next part of this section is based on a specific case study of a small company, which considers the move to SaaS solutions. This section is focused on the practical application of the preceding conclusions. Last section aims at the prediction of development of ICT business in the upcoming years, with an emphasis on SaaS and related technologies. The second part is trying to find answers to the questions "Whether," "When" and "How" will SaaS affect the market of information technologies, their deployment and business models of future anticipated expansion model of Software as a Service. SaaS maturity model is also discussed as well as specificity of the Czech market.
