The increasing performance of Platform as a Service using virtualization
Schramm, Michal ; Voříšek, Jiří (advisor) ; Sokolovský, František (referee)
This thesis discusses the increasing performance of Platform as a Service using virtualiza-tion. It focuses on the new trends in the provision of IT services, which is virtualization. Possibility of huge savings and improvement of performance of the hardware is interesting for every company, that's why a lot of companies want to migrate to the vir-tual infrastructure. The first part defines IT service and its categories. It describes the development of IT service and brings definitions based on multiple resources. The second part characterizes cloud computing services. This part focuses on the actual composition of the various forms of technology deployments and distribution models. Further focuses on the main benefits and disadvantages of the types of cloud computing. The focus of third part is virtualization. This part presents a five-step procedure for that matter the transition to virtualization. Chapter helps to understand the value that may pose to the enterprise virtualization. The fourth section deals with virtualization in a particular environment. This part brings specific solution of infrastructure virtualization together with the creation of the virtual machine for a new user.

Comparison of virtualization platforms from Microsoft and VMware
Kos, Jakub ; Nedzelský, Roman (advisor) ; Novotný, Ota (referee)
This bachelor thesis deals with the comparison of virtualization tools of two leading com-panies in the field of virtualization, namely Microsoft Hyper-V and VMware Workstation. In the introduction is summarized historical development, basic concepts and defined the concept of virtualization. The larger part of the thesis deals with the theoretical foundations and descriptions of the various types of virtualization. In this part, the reader is acquainted with the different type's virtualization. Explains the types sectors and virtualization, the reader gets a wider awareness on the topic virtualization. In the practical part are presented and compared both programs. The programs were compared in the performance but also in terms of user-friendliness. The systems achieved according to the total score of approxi-mately same performance, but there are differences in some areas.

Server and application virtualization via Docker
Tomášek, Patrik ; Pavlíček, Luboš (advisor) ; Bruckner, Tomáš (referee)
This bachelor thesis covers virtualization at level of operation system using a new solution called Docker. The aim is to introduce the topic and to describe how to create Docker container. The key to achieve those objectives lies in identifying and studying available relevant materials and processing the information gained from the study in order to create an application container. As an introduction to the topic of Docker, the theses briefly mentions the history of virtualization and currently used sorts of virtualization. It describes Docker and necessary knowledge for basic understanding of the issue and further practical sections of thesis. The main part of this thesis sheds light on installation and configuration of Docker, download and launch of already existing Docker container. Furthermore it documents how the author designs and creates his own application container with preselected app.

The use of cloud computing technology in practice
CHALUPSKÝ, Petr
This bachelor thesis is in its theoretical part focused on the concept of the cloud computing and the technologies associated with this phenomena of this modern era. The reader will be introduced to commonly used terms and practical examples. The thesis also deals with the platform of Windows Azure in more detail. The practical part is based on the evaluation of the survey focused on the use of cloud computing in practice, particularly in an environment of Czech companies. This is followed by the design and evaluation of solutions in a model company where they competes on-premise and SaaS solutions for the same purposes.

Sustainability Analysis of Small and Medium Enterprises
Vojtěšek, Cyril ; Basl, Josef (advisor) ; Gála, Libor (referee)
The Diploma thesis analyzes the attitude of small and medium Czech enterprises towards the Green IT and sustainability concept. Several practices such as consolidation and virtualization of servers, desktop virtualization, cloud computing, energy management, dematerialization and recycling are discussed with regards to their contribution to global sustainability. The common denominator of most of the Green IT practices is the energy consumption reduction. The increasing information technology's demand for energy is viewed as a major contributor to the global carbon footprint and Green IT practices are assessed in terms of how much energy can be saved by incorporating them in a company policy. Besides energy consumption material aspects are another significant part of Green IT. Both the toxicity of certain materials used in the manufacturing process and the increased need for proper recycling of electronic waste are discussed in respective chapters. Information technology does not only add to the global carbon footprint, but it can also provide means to reduce the emissions of other sectors. Companies can reduce their energy consumption by improving logistics (smart logistics) or buildings (smart buildings) efficiency. Teleworking is another practice which enables millions of people work outside their office and contributes to global sustainability. The analytical part presents a survey of Czech small and medium enterprises and their attitude to Green IT. The main objective of the survey is to find out how many companies have implemented Green IT into their company policy. Company representatives report on which Green IT practices they have adopted and why. Responses are analyzed and findings and conclusions are presented.

Comparison of virtualization systems technologies
SLÁDEK, Lukáš
This bachelor thesis deals with the description of virtualization technology systems commonly used in IT practice. It discusses basic concepts, defines the term virtualization. The larger part is devoted to analysis of the principles on which the virtualization works. We can find here the concept of hardware virtualization, software virtualization, paravirtualization, hypervisor and other. All of these concepts are explained. The following is a description of products that are in common practice used to virtualization, including the description of their architecture and components of virtualization systems. Three representatives of hardware virtualization are described in detail -- VMware ESXi, Microsoft Hyper-V, Xen Hypervisor and two representatives of the software virtualization -- Oracle VM VirtualBox and VMware Workstation as well. These five products are tested and evaluated in the last part of the thesis. Based on the overall benchmarking are systems approximately the same performance, but in particular tests we can find differences.
