Cloud computing and its application in practice
Kozák, Jaroslav ; Svoboda, Jiří (advisor) ; Kunstová, Renáta (referee)
Goal of this work is to define the concept of cloud computing. Then I analyzed the market for cloud computing, the use in business for small and medium enterprise. The work deals with the analysis of the Czech market, SaaS, IaaS and for the world market we provide an overview of catalogs, which provides cloud computing providers. After analyzing the markets deal with a case study to compare the solution of the classical way and the use of technology solutions for cloud computing. The definition of cloud computing, I used the definition of many foreign authors, and the definition of NIST. When analyzing the market, I searched online applications and SaaS applications and evaluate whether the SaaS model, or ASP. In the case study I conducted an analysis of TCO costs for ICT / IT solutions in the classical pathway and the use of cloud computing. When we came out in the analysis as a better solution using cloud computing. As the main contribution of the paper I define a case study that compares the address ICT / IT in a classic way, using cloud computing. In this case the forecasts were to materialize, that cloud computing is based on the cheaper end customer. The structure of work is the definition of the concept and its distribution for better understanding. Then I planted the notion of cloud computing in its historical context, I can answer two questions, namely whether it is a buzzword, and why cloud computing flourishes today. Then I conducted a market analysis, cloud computing, when I tried to search and select products that I use for finding work in the case study, comparing two solutions.

Cloud Computing as a BCM tool
Lukášová, Pavlína ; Chlapek, Dušan (advisor) ; Dotlačil, Jaroslav (referee)
This thesis deals with possible interconnections between two concepts playing a big role in contemporary business and IT world. These concepts are Business Continuity Management and Cloud Computing. In the scope of this thesis there are certain areas identified where both concepts are complement, where Cloud Computing brings new opportunities for Business Continuity Management and where could possible problems arise during particular implementation. From the BCM perspective the impact lies on IT services, from the Cloud Computing perspective the thesis deals especially with security aspects. The thesis is also aimed at the characteristics of higher education and basic differences from commercial sphere. Based on defined differences and identified interconnections between BCM and Cloud Computing, the thesis argues for usage of suitable Cloud Computing solution for higher education regarding Business Continuity improvement. The multi-criterion comparison of several Infrastructure-as-a-Service solutions stems from this analysis focusing on technical, financial, and Business Continuity aspects. The result from this comparison together with conclusions from previous chapters serve as an input for subsequent practical proposal of Cloud Computing solution and its verification against Business Continuity improvement in specific conditions on University of Economics in Prague. The proposal is also represented by strategic map.
