Effects and problems of cloud computing
Hanzlová, Marie ; Pour, Jan (advisor) ; Kačmář, Dalibor (referee)
This thesis focuses on effects and problems from a customer perspective. The main objective of this work is to create a fair idea of cloud computing services. Fair idea means primarily effects, which can occur while using cloud services, but also effects to which entities must face before and after they decide to use these services. The main part of the work is devoted to the problems and effects of cloud preceding section which focuses on general information such as main idea, principle of operation and characteristics of cloud computing. This section includes characteristics of deployment and delivery models of cloud computing. The general information section is followed by chapters containing summary (operational, economic and personal) effects and problems. These issues mean both security issues and technical problems such as blackouts, legal aspects and other issues that should be considered before launching cloud computing services. This follow-up analysis shows the appropriateness of deploying cloud services in three specific environments. These are small companies whose main activity is not associated with an IT area. The interview was done in these companies and it was collected basic information about the company on core business and IT functions. Analysis was performed based on information and dismantled effects and problems in the theoretical part which shows mainly for selected businesses, whether it has a sense to deal with cloud computing services.

Providing ICT services in the cloud
Neumann, Jiří ; Voříšek, Jiří (advisor) ; Kopecký, Roman (referee)
This thesis focuses on the ubiquitous cloud computing trend and particularly Software as a Service. The main goal is to specify all pros and cons of this concept for its customers and also cloud providers. The global perspective is then specified to Software as a Service and deployment of SaaS ERP products. The next goal is to define an appropriate method to analyze a company's needs prior to switching to the cloud. Furthermore, recommendations as to whether the cloud is better than an on-premise version should result from the previous analysis. Another aim is to form a process for successful switch to the cloud and ensure all important aspects of using cloud services are covered. Theoretical findings and recommendations are used in a practical example of SaaS ERP deployment. To reach all goals, a theoretical analysis of all available monograph and electronic sources, covering cloud computing and consultations with experts from the company; Algotech BSC, were used. The main added value is in the dual point of view on the topic, from customer's and provider's viewpoints with a more detailed focus on ERP. The author suggests the right procedure for switching to the cloud, guidance with calculating ROI, TCO and preparing all necessary contracts and agreements.

Běloch, Tomáš ; Kunstová, Renáta (advisor) ; Kapitán, Petr (referee)
Focus of this diploma thesis is on cloud computing topic. Cloud computing is current trend that changes the method of IT services providing. The concept of cloud computing model is based on a provision of IT resources through services. This model offers companies many advantages. The aim of this diploma thesis is to provide an overview of the motivational forces, barriers and their solution in the transition of small and medium businesses to products in the cloud. The theoretical part deals with economic and technological aspects arising from the use of cloud computing model. The next stage is provided with an overview of adoption of cloud computing services in the Czech Republic and current trends. The practical part is focused on the research of motivation aspects and barriers resulting from adoption services built on the cloud computing concept. The main contribution of this thesis is primarily in providing an overview of motivational aspects and research-based barriers in the environment of Czech companies. This overview could help to these company representatives, who are considering deployment of cloud based services, but are struggling with the barriers that this model brings.

Cloud computing with regard to technological aspects and changes in infrastructure
Vítek, Daniel ; Donát, Jiří (advisor) ; Bruckner, Tomáš (referee)
This thesis discusses the new way of delivering IT services over the Internet widely known as cloud computing. In its opening part, cloud computing is put into a historical context of the evolution of enterprise computing, and the dominant issues the IT department faces today are mentioned. Further, the paper deals with several components that make up the architecture of cloud computing and reviews the benefits and drawbacks an enterprise can have while it adopts this new model. One of the primary aims of this thesis is to identify the impact of the technology trends on cloud computing. The thesis brings together four major computing trends, namely virtualization, multi-tenant architecture, service-oriented architecture and grid computing. Another aim is to focus on two trends related to IT infrastructure that will lead to fundamental changes in IT industry. The first of them is the emergence of extremely large-scale data centers at low cost locations, which can serve tremendous amount of customers and achieve considerable economies of scale. The second trend this paper points out is the shift from multi-purpose all-in-one computers into a wide range of mobile devices dedicated to a specific user's needs.

Cloud computing and its model Platform-as-a-Service
Theier, Radek ; Burkoň, Lukáš (advisor) ; Feuerlicht, Jiří (referee)
This paper deals with the way of providing IT services via the Internet, which is nowadays known as cloud computing. It further focuses on the model Platform-as-a-Service (PaaS), in which vendors offer Web-based development-platforms for developing and deploying full programs online. The main objective of the paper is to introduce this relatively new approach to developing applications as well as to shed light on related advantages and obstacles, thus contrasting with traditional ways of developing applications. The thesis also contains a market analysis of contemporary PaaS platforms, which divides possible solutions into three basic categories. The purpose of the analysis is to make it easier for potential customers to orientate on the market and help them to pick the right platform which suits their requirements best. In the practical part there is a demonstration of the process of creating a simple database application using one of the platforms described earlier in this paper. At the end of the thesis the author makes an attempt to forecast the future of the whole area of cloud computing and the model Platform-as-a-Service.
