Portability of Distributed Computing in Cloud Infrastructures
Duong, Cuong Tuan ; Ondrák, Viktor (referee) ; Kříž, Jiří (advisor)
The master’s thesis focuses on analysis of solution to distributed computing of metage-nomics data in cloud infrastructures. It describes specific META-pipe platform based onclient-server architecture in infrastructure of public academic cloud EGI Federated Cloud,sponsored by european project ELIXIR-EXCELERATE. Thesis is focusing especially onopen-source software like Terraform and Ansible.

Design of laboratory exercises in the field of network programmability
Dubovyi, Dmytro ; Polívka, Michal (referee) ; Škorpil, Vladislav (advisor)
The aim of the graduation thesis is to evaluate the current development in the field of SDN and the possibility of programmability of SDN elements using the application programming interface. The first theoretical chapter describes the following: the basic architecture of SDN, the traffic within SDN between its individual layers, the communication protocols Southbound interface and Northbound interface. The second chapter of the thesis deals with the programmability of SDN elements with the help of API. The third theoretical chapter describes the current development in the field of SDN. The practical part of the thesis is devoted to creation of two laboratory tasks dealing with the programming of the SDN API. Laboratory tasks include BIG-IP programming from F5 Network and routers from Arista Network. Programming is done using Python via REST API for BIG-IP, or eAPI for Arista EOS. The Ansible setup tool is also used for the same purpose.

Utilization of Linux Containers for HW/SW Co-Design
Juřica, Jiří ; Přikryl, Zdeněk (referee) ; Hruška, Tomáš (advisor)
In this bachelor thesis a way of replacement standard virtual machines by Linux containers is described. The goal is to create a~fully working system for performing parallel jobs with prepared environments for software build and test purposes. For containerization the Docker platform was chosen, which is used with automation tool for computers preparation. The system is also connected with continuous integration tool called Jenkins. This solution proves that usage of the Linux containers is more efficient than older virtualization technologies. The due time of each job was shortened about 24 % in average. The main benefits of this thesis is the comparison of two ways of virtualization and the introduction to the Docker technology.

Operator for MariaDB Galera Cluster in OpenShift
Javorský, Lukáš ; Malinka, Kamil (referee) ; Januš, Filip (advisor)
Hlavným cieľom bakalárskej práce je vytvoriť riadený systém databázových serverov, ktorý je schopný sa adaptovať a reagovať na ich aktuálne zaťaženie. Riešenie tohto problému nachádzame práve v najnovšej platforme, určenej pre riadenie a nasadenie OpenShift 4 postavenej na základoch softwaru Kubernetes. Použitím operátora ako mysle celého OpenShift clustra, zodpovedného za nasadenie, vyvažovanie záťaže, detekciu zlyhaní a zotavenie po zlyhaní MariaDB kontajneroch, môžeme zabezpečiť, že bude databáza bezproblémovo fungovať, dokonca aj pri najvyšších špičkách záťaže počas dňa. Na replikáciu medzi databázovými servermi sa využíva softvér Galera vo vnútri každého MariaDB servera, ktorý zabezpečuje konzistentný obsah.

A tool for generating a random configuration of a cyber arena
Matisko, Maroš ; Kolařík, Martin (referee) ; Uher, Václav (advisor)
The master's thesis is focused on the design and implementation of a tool for generating configuration named Ansible. The result of using this tool is generated configuration, which contains random values chosen according to specified parameters and it was deployed on a virtual testing infrastructure. The theoretical part describes approaches of network automation in the process of deploying and configuration of network devices called Infrastructure as code. It also describes programme Ansible, which will be using the output of the implemented tool. The practical part of the thesis is focused on designing the functionality and internal structure of the tool, implementation of the tool and testing implemented tool as well as generated configuration.

MITM Attack Automation Using Single-Board Solution
Podlesný, Šimon ; Letavay, Viliam (referee) ; Pluskal, Jan (advisor)
Thesis is focused on design of MiTM attack with use of modern approaches in IT infrastructure. Especially it's focused on how to simplify configuration of single-board computer for penetration testing purposes by creating scalable infrastructure for device configuration and control. Proposed solution allows the usage of complicated attacks by trained staff while not limiting users with experience in network security. While today, applications capable of MiTM attacks are monolithic and device-centric, proposed solution considers the device providing MiTM just as one part of the solution and also focuses on other problems like data exfiltration or hash cracking.

Cluster Management
Hlaváč Ďurán, Dominik ; Očenášek, Pavel (referee) ; Trchalík, Roman (advisor)
The bachelor thesis focuse on the design of a system for complex administration and monitoring server cluster based on the Red Hat Enterprise Linux/CentOS operating system using the Ansible tool. In the thesis there is a brief description of used technologies and issues of management of server cluster. The tool, that was implemented by us, provides preparation of the environment for system deployment, remote installation and configura- tion of applications, hardware registration, software and hardware system monitoring and much more. Consequently, there is a comparison of the resulting system with existing tools. Practical examples of the issue dealt with is also part of the thesis.

Virtualization platform for cyber range
Horváthová, Estera ; MU, Pavel Šeda, KPSK FI (referee) ; Lieskovan, Tomáš (advisor)
The bachelor thesis deals with the creation and operation of sandboxes for selected scenarios using the sandbox-creator tool, which is compatible with the KYPO project and uses the OpenStack platform. The theoretical section describes the technologies and tools used to create training platforms. Virtualization, containerization and cloud computing are described in the technologies and VirtualBox is described in the tools, Docker or OpenStack. The work also describes selected cyber range platforms that use these technologies. The practical part describes the compatibility of the selected platform with the KYPO project, the configuration tools used, the preparation of the experimental environment, the creation and operation of sandboxes for laboratory exercises, which are listed in the annex.

Automatic configuration of virtual infrastructure
Kadlíček, Jan ; Mašek, Jan (referee) ; Uher, Václav (advisor)
This master thesis focuses on the issue of automation of virtual infrastructure and available tools such as Ansible, Terraform and Puppet. The individual tools are compared here in sequence for installations or configuration creation. The result of this semester thesis is the selection of a suitable tool for automation of virtual infrastructure.
