Rozšíření SOA do platformy Cloud Computing
Qylafku, Denis ; Svatá, Vlasta (advisor) ; Toman, David (referee)
The aim of my diploma thesis is to introduce cloud computing as an alternative to traditional internal information technology and its benefits for a company. Diploma thesis focuses on three main goals. The first one concerns advantages and disadvantages of cloud computing in comparison to internal information technology. The second one is identification of possible processes and services available for migration into cloud computing. The third goal of the diploma thesis is development of investment analysis which compares not only initial costs on internal information technology and cloud computing, but also costs of both variants within three years. The main contribution of the diploma thesis is to define whether the cloud computing is economically beneficial for the company or not. The argument for categorizing cloud computing is in the reason that the company does not have to use all services within the cloud computing but only these, which the company considers as the most beneficial from cost and operation point of view. Another contribution of the diploma thesis is deployment of data, services and processes into a chosen cloud computing platform. Investment analysis allows through cost comparison of both options understand whether it is more beneficial to choose cloud computing or internal Information Technology platform. During this decision making the company also considers its business character and the fact whether the company operates locally or globally.

Integration of SaaS applications into business information systems
Randová, Libuše ; Gála, Libor (advisor) ; Burkoň, Lukáš (referee)
The thesis deals with an analysis of approach methods, that can be used in integration of SaaS model applications into business information systems. To this end it presents business information systems. Description of these was performed from a general viewpoint. A description of what business information systems are was provided as well as a description of their architecture and service-oriented architecture. Business information sysstems were then described from a development/operation point of view, particular phases of the corelation between business and ICT were summed up, as well as ICT service supply models and development and operation alternatives. At the end of the chapter, a description of business information system components was performed. Services were described in the next chapter - first generally, with special interest in service characteristics and categorization. Furthermore I explored the concept of 'Anything as a Service' (XaaS), providing a summary of what can be provided as a service. Then a distribution model for Software as a Service (SaaS) was described along with its characteristics, parameters, benefits and limitations. At the end of the chapter cloud computing, its characteristics and models of implementation were described and the most notable providers were presented. The next chapter contains a description of integration and is targetted mostly on the description of system integration, on the system integrator as a person, on a description of technological means, usable in the integration itself. The next chapter is dedicated to a description of integration scenarios of business IS using SaaS applications. In the next chapter, an approach to the analysis of integration scenarios is defined, based on various viewpoints. The last chapter contains an assesment of particular integration scenarios and a consequential evaluation performed along evaluation criteria.

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.

Classification of Services in Cloud Computing
Osecký, Michal ; Burkoň, Lukáš (advisor) ; Feuerlicht, Jiří (referee)
From the fact that there are different approaches to the definition of the term cloud computing follows that the approaches to the description of its inner organization also vary. In the next part, the thesis looks into these approaches and briefly compares them. It further describes the economical model of this way of providing IT services, which is a result of the approach developed within the technological and economical Software-as-a-Service model. Attention is paid to the basic technological questions of cloud computing, i.e. mainly to the design of services, management of databases, data safety and scaling of the computing resources. The final analysis of services provided within cloud computing is first done vertically, i.e. it is a comparison of the different types of services relating to the individual layers of the technological model, starting with the provision of hardware and computing services, over platform services to the Software-as-a-Service layer of the model. Subsequently, a comparison of services of several big players is made in the individual layers, i.e. horizontally. The thesis focuses on the on-demand way of providing IT services, currently known as cloud computing. Attention is paid specifically to the organization and interoperability of the provided IT services within cloud computing, as understood today by the expert public and commercial sphere. First the thesis deals with various possible definitions of the term cloud computing, it summarizes these approaches and attempts to outline the term and its determining attributes. This outline is then followed by describing the historical development of the distributed applications and older models of providing ICT services, from which cloud computing originates. The goal of the thesis is to describe the issue of classification of services in cloud computing and make the above-mentioned comparisons in an clear way and based on suitable metric. As a conclusion, the author presents his view on the future of the cloud computing and sums up the whole thesis.
