Available Solutions for Server Clustering
Bílek, Václav ; Čejka, Rudolf (referee) ; Kašpárek, Tomáš (advisor)
The goal of this master thesis is to analyze Open Source resources for loadbalancing and high availability, with aim on areas of its typical usage. These areas are particularly solutions of network infrastructure (routers, loadbalancers), generally network and internet services and parallel filesystems. Next part of this thesis is analysis of design, implementation and plans of subsequent advancement of an fast growing Internet project. The effect of this growth is necessity of solving scalability on all levels. The last part is performance analysis of individual loadbalancing methods in the Linux Virtual Server project.

Virtualisation and Optimalisation of IT in a Production Company
Popelka, David ; Hégr, Robert (referee) ; Ondrák, Viktor (advisor)
The master‘s thesis deals with the implementation of server virtualization in the Entity production, s.r.o., which is a small company by it’s size, but needs modern IT technologies for the normal operations. The thesis shows how to reuse the server virtualization technologies from large corporations, that have been unavailable to small business companies in past. It also design show to optimize the current IT environment.

High availability Microsoft Sql Server
Pyszko, Pavel ; Lattenberg, Ivo (referee) ; Zeman, Václav (advisor)
The thesis contains a complete theoretical overview of high availability technologies in Microsoft SQL Server. For each technology, guidance is provided for the deployment of technologies. Technologies are analyzed from a security perspective, they are determined advantages and disadvantages of using technology in practice and is determined the optimal variant of use of the technology. High availability technology are compared with each other and is given the availability of individual technologies in versions of MS SQL Server. The thesis contains three scenarios with practical examples of using technology for high availability in practice. It provides an analysis of high-availability features in Oracle and are subsequently compared high availability features in Oracle environments with high availability technology in MS SQL Server.

QoS in a computer network of VŠE
Kalina, Tomáš ; Pavlíček, Luboš (advisor) ; Beneš, Jiří (referee)
The diploma thesis is focused on analysis and deployment of Quality of Services (QoS) in a computer network of The University of Economics in Prague (VŠE). The thesis describes the main QoS technologies focusing on technology Diffserv and its deployment with using available network devices in computer network of VŠE. In thesis the needs of network services and protocols for quality of services with division into different classes of services according to priority are discussed. The thesis explains the benefits and drawbacks of deploying QoS in the environment of VŠE with regard to wired and wireless network. In the practical part recommendations are applied to the production network and subsequently the benefits of modification are evaluated.

High-availability solutions for network filesystems in Linux
Kravec, Martin ; Pavlíček, Luboš (advisor) ; Vadinský, Ondřej (referee)
The goal of this paper is to inform readers about high availability problematics and provide basic overview of free technologies you can use to achieve high availability. I focus mainly on solution of problems caused by hardware failures. Document can by used to gain basic knowledge needed for configuration of your own solution. In practical part I will try to realize high available cluster using free technologies and compare performance of different filesystems on this platform. Document will provide instructions for choosing and testing appropriate filesystem for specific configuration that can be used in production environment.

Redundancy in data networks
Šoun, Jan ; Pavlíček, Luboš (advisor) ; Beneš, Jiří (referee)
This thesis focuses on redundancy in data networks and on technologies which are used to achieve high availability in network infrastructure. This thesis is based on industry standards published by well-known standardization authorities. One proprietary technology which can effectively replace these standards and simplify the whole network is also presented in more detail. The theoretical part individually describes all such technologies and standards. The practical part deals with an appropriate combination of these technologies and their application in a specific product environment. This work is meant to describe the whole concept of high availability in network infrastructure and should be instrumental in understanding how these technologies are deployed in practice.

virtualization stations
Vlček, Michal ; Pavlíček, Luboš (advisor) ; Havlíček, Jan (referee)
This thesis aims to explain virtualization and its use for the implementation of virtual classrooms. Reader is gradually introduce, what is virtualization, how virtualization works, what has parts, what are the technologies used and how many is this virtualization. Reader is gradually acquaint with the concept of virtual classroom, how virtual classroom works and what are the solutions of virtual classrooms. Individual solutions of virtual classroom are explained and compared. At the end of this work is the selection of solutions virtual classrooms, and example of actual implementation of virtual classrooms, including the price of solution. The work has to show possible and effective solution of the virtual classrooms.

High availability storage for virtualized servers
Zvala, Tomáš ; Pavlíček, Luboš (advisor) ; Borka, Michal (referee)
This thesis aims at providing basic overview of technologies capable of providing high-availability for virtualized servers. It focuses mostly on technologies that are cheap and available even to the smallest companies. Reader is presented with an introduction to hardware technologies, that can be used to connect storage, software technologies available to share the storage and finaly there is a quick introduction to virtualization solutions of major market players. Aim of the project part of this thesis is to explore the options of building small virtualization cluster based only on common hardware and opensource technologies on Linux platform.

Zajištění dostupnosti IT infrastruktury pro podporu firemních procesů
Zima, Radek ; Pavlíček, Luboš (advisor) ; Dušek, Daniel (referee)
Cílem práce je podat ucelený přehled o aktuálních technologiích sloužících k zajištění dostupnosti IT infrastruktury v podniku. Autor má zkušenosti nejen s konkrétními technologiemi a přístupy k zajištění vyšší odolnosti jednotlivých komponent serveru vůči výpadku (ukládání dat, napájení, řízení toku vzduchu, ochrana paměti, ?) , ale i se softwarovými produkty, které zajistí redundanci celého serveru. Tento přístup byl otestován i v případové studii, kde proběhla analýza stávající situace ve vybrané společnosti a nalezeny funkce poskytované jednotlivými komponentami infrastruktury. Kromě detailního zmapování situace byla nalezena i slabá místa a doporučeno řešení.
