Practical testing of current virtualization technologies, comparison of services on Czech and foreign market
Rudolf, Michal ; Bruckner, Tomáš (advisor) ; Pavlíček, Luboš (referee)
The main objective of this work is to provide information on the newest trends in hardware virtualization technologies and Cloud computing. At first, the work provides information on the functioning principles of all types of virtualization technologies. Key terminology relating to virtualization technology is explained here. The main part of the work comprises practical testing of chosen virtualization technologies performance. Performance testing is done by means of benchmark applications that measure the performance of the most important system parameters. During the testing, virtualization technologies are compared according to the attained results. The result of the testing is a summary of performance overhead of individual virtualization technologies compared to physical server without a virtualization layer. The last part is focused on identification of main players on expanding Cloud service market, whose services present an alternative to purchasing one's own hardware.

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. The last aim of this thesis is to clarify the economic impact of cloud computing in terms of costs and changes in business models. The thesis concludes by evaluating the current adoption and predicting the future trend of cloud computing.

Comparison of Microsoft Hyper-V and Citrix XenServer
Ferbr, David ; Pavlíček, Luboš (advisor) ; Palovský, Radomír (referee)
This work aims at comparison of the two freely availabe virtualization solutions developed by commercial companies. It analyses the possibilities provided ty these products, their management tools and procedures and the consequences resulting from their differences. These goals are achieved through studying the available resource about the products and virtualization in general, followed by doing a practical test of running the products. The work provides the reader with guide to choosing the right virtualization tool and shows the ways how to work with it. It starts with explaining the basic terms in the area of virtualization and continues by introducing the products and their features and how to manage and use them, finishing with the conlusive evaluation.

Business continuity management and virtual machines
Salák, Ondřej ; Pavlíček, Luboš (advisor) ; Martanová, Kateřina (referee)
The aim of this work is to provide a basic overview of ways to improve business continuity management and planning using virtualization. First, the reader is briefly introduced to the concept of Business continuity management and the concept of virtualization. Then the relationship between these two areas is analyzed. Finally, I chose to analyze a set of utilities, which come with VMware vSphere product, which is the product of VMware Company. The aim of the practical part is to verify the functionality of some of these tools.

Selected consequences of society‘s informatization
Zíma, Stanislav ; Rosický, Antonín (advisor) ; Pavlíček, Antonín (referee)
The aim of the thesis is to describe selected consequences of informatization on the basis of three different views' critical synthesis. First view is an historical perspective focused on medialisation of information and its influence on shaping of man's thinking. On the background of technological progress are shown the milestones in changing of social reality. Another view is to describe the infromation society as a present phenomenon with its general characteristics. The last point of view is based on the hypothesis sof Global brain, which describes mankind as a network of nerve cells, connected to global computer network. Thesis is not intended to be a comprehesive overview of the informatization's consequences but it tries to explain basic issues related to information society.

Virtualization aplication for monitoring networks
Kafka, Jan ; Pavlíček, Luboš (advisor) ; Gála, Libor (referee)
Virtualization is a promising information technology industry today. Whether for reasons of economies, achieve high availability of services, or facilitate the administration etc., gets more and more benefits.With the development of virtualization has been the transition from simple emulation, which was simply procesed as the code processor and simulated a complete computer, the hardware assisted emulation or Paravirtualization make the directing of this process has become almost negligible - literature generally indicates less than three percent. Virtualization also opens the way into the most demanding server applications, where in addition to high availability of services depends also on the optimal use of available hardware resources.The first part is a description of the reasons brought the benefits of deploying a virtualization server environment. The following section discusses virtualization techniques, their characteristics, advantages and disadvantages and most common server virtualization products. In the next chapter are explained the ways to achieve high service availability in a virtualized server environment, and examples of products of VMware, which is the industry leader. Chapter discussed concepts such as cold migration, live migration, technology VMware High Availability, VMware Fault Tolerance, and more. The last chapter is devoted to the practical part of the bachelor thesis. Describes hardware preparation for the experimental environment, the setup, configuration, problems during preparation laboratory network and the installation of dedicated virtualization product, VMware ESX 4.0 64bit. In last part will be describe installation and configuration monitoring software, OpenNMS on server virtualization. At the end, will be examination how fail activities impact on virtualization monitoring software and how rescue this software application VMware ESX 4.0.

Virtualization in IS/ICT
Naiman, Michal ; Gála, Libor (advisor) ; Kašpar, Jaromír (referee)
The goal of the thesis is to examine and assess actual portfolio of products on the market for server visualization and to compare performance of individual products with performance of the physical machine. The research and the assessment of the actual portfolio will be carried out with the focus on current trends in the area of server virtualization, reasons for realization, and important aspects for their successful implementation. The comparison will be carried out in areas of supported platforms, hardware emulation spectra, hardware limitations, licensing and prices. Further it will be performed comparison in the form of benchmark performance in areas of CPU, RAM, hard-drive throughput, and network throughput of most commonly used products for server virtualization.
