Distributed Tasks in an Enterprise Computing Environment
Tichavský, Milan ; Rychlý, Marek (referee) ; Burget, Radek (advisor)
V architektuře orientované na mikroslužby jsou zprávy běžně používaným prostředkem pro komunikaci mezi jednotlivými službami. Obecně je zde potřeba naslouchat zprávám odeslaným na sběrnici a reagovat na ně spouštěním úloh. Tato práce prezentuje všechny podstatné úvahy k vyřešení tohoto problému. Přichází s rámcem pro spouštění úloh, který vykonává úlohy v libovolných kontejnerech na OpenShiftu. Řešení se skládá z API napsaného ve Flasku, které obsahuje spouštěcí logiku, a klienta, který přes STOMP příjmá zprávy ze sběrnice a poslílá je na API. Součástí jsou i testovací scénáře, které předvádějí funkčnost celého systému. Řešení je vyhodnocováno porovnáváním s existující aplikací postavené na nástroji Jenkins. Rovněž je diskutovaný alternativní návrh využívající Tekton. Druhým problémem, kterým se tato práce zabývá, je provádění pravidelně naplánovaných úloh. Namísto implementace vlastního řešení navrhuje použití Kubernetes objektů CronJob.

Automation of Cyber Arena backup and recovery processes in Ansible AWX
Fišarová, Veronika ; Lieskovan, Tomáš (referee) ; Stodůlka, Tomáš (advisor)
The master thesis focuses on the cyber range Cyber Arena and the OpenStack cloud platform, on which the Cyber Arena is built. The theoretical part of the work is dedicated to three essential technologies used in the construction of cyber ranges. These technologies are virtualization, containerization, and cloud computing. In the next part, the analysis focuses on the OpenStack platform and its essence in the Cyber Arena. This is followed by an introduction to the Ansible AWX automation platform, which acts as an intermediary between the Cyber Arena and OpenStack. The last part of the theory is dedicated to the issues of backups and recovery of OpenStack with the aim of improving the life cycle of the Cyber Arena. In the practical part, the creation of a development environment is described, consisting of the OpenStack platform and the AWX platform, in such a way as to best match the environment with the Cyber Arena. In this environment, an Ansible project is then implemented, which automates the creation of backups and subsequent recovery of the main OpenStack services. The project is implemented in such a way that the processes are transferable to new versions of OpenStack while maintaining the same deployment method.

Framework for a Web Internet Service
Hájek, Filip ; Smrčka, Aleš (referee) ; Hrubý, Martin (advisor)
The goal of this thesis is to design and implement a containerized web service, which provides the ability to create and run users' tasks. The task is only an abstraction over some particular implementation of computation. The task runs as a Docker container. The thesis also implements user management and the method of running task charging. The system architecture consists of a REST API web server and a user web environment. Worker applications are an essential component of the system. They start user tasks assigned by the server. The system was implemented using the .NET 6 framework in programming language C#. The run of the service has been simulated in a Docker environment. The service integrates existing Auth0 and Google Cloud Storage services. The result is an internet service deployed on a public cloud server.

Web application for training and validation of machine learning models
Svoboda, Jan ; Mucha, Ján (referee) ; Galáž, Zoltán (advisor)
The delegation of resource-intensive operations to the server-side computers is an ongoing trend. Containerized applications serve as an abstraction over the servers and provide needed scalability. The architecture of the implemented application utilized as a platform for an asynchronous execution of training and validation of machine learning models is heavily influenced by the containerization. Individual users of a web application are given a separate container with prepared environment for running a model with selected parameters. Status of the training process is monitored by the application. After the result is obtained the analysis takes place and components providing visualization are rendered in the user interface.

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.

Communication infrastructure virtualization platform
Stodůlka, Tomáš ; Martinásek, Zdeněk (referee) ; Uher, Václav (advisor)
The thesis deals with selection of infrastructure virtualization platform focusing on containerization with sandboxing support and with following examination of its difculty. The work begins with an explanation of the basic technologies such as: virtualization, cloud computing and containerization, along with their representatives, that mediate the technology. A special scope is defned for cloud computing platforms: Kubernetes, OpenStack and OpenShift. Futhermore, the most suitable platform is selected and deployed using own technique so that it fullflls all the conditions specifed by thesis supervisor. Within the difculty testing of the selected platform, there are created scripts (mainly in the Bash language) for scanning system load, creating scenarios, stress testing and automation.

Containerization of Database Detectors
Oberreiter, Michal ; Kočí, Radek (referee) ; Smrčka, Aleš (advisor)
This thesis deals with containerization of command-line applications including containerization of existing tools for database content analysis. The thesis is a part of Testos platform, which aims at software testing automation. The goal was to design and implement a solution that would be both universally usable for command-line applications and at the same time flexible enough to accommodate database detectors and their specific requirements. Docker was chosen as the containerization platform, on which a management system was built. This system provides both a graphical user interface and an application programming interface. The result allows for easy application management and output retrieval. The primary contribution of this thesis is the streamlining and simplification of running command-line applications with specific dependencies. These features come in form of abstracting the underlying mechanisms and providing a graphical user interface.

Rail transportation as an alternative to maritime transport for freight forwarding company
Herain, Jan ; Kolář, Petr (advisor) ; Estrade, Vanda (referee)
This thesis addresses various concerns of maritime and rail transport of goods between East Asia and the Czech Republic. Its conceptual part outlines the present situation of sea freight transportation with the emphasis on the container use. Furthermore, the thesis describes the rail infrastructure between East Asia and Europe. In the how-to part, the author describes working procedures of an actual freight forwarding company carrying out an import shipment from China into the Czech Republic, utilising ocean and rail carriers. The last part of the thesis contains a summary of the main differences when employing various types of transport, and of their comparison based on the time of the shipment and on its cost.

Kuncová, Andrea ; Novák, Radek (advisor) ; Mádl, Jan (referee)
The thesis is divided into two parts. The first theoretical part defines the basic concepts related to combined transport and its current trends and supporting projects. It is focused on the structure of the European transport networks, with emphasis on road and rail transport. The practical part was developed in collaboration with the company PELMI, Ltd. and is focused on the analysis of the current situation of combined transport and price comparison of straight road and combined transport of containers. There is evaluation and definition of the conditions in which is advantageous / disadvantageous to move the containers road carriage to continental combined transport involving rail in conclusion.
