Module Orchestration of Multitenant Systems
Freyburg, Petr ; Pavela, Jiří (referee) ; Smrčka, Aleš (advisor)
This thesis deals with the creation of multitenant systems and their orchestration. The creation process is based on the transformation of an existing monolithic but modular system in order to extract a selected module. The resulting solution includes an infrastructure that enables secure transmission between the information system and the extracted module. This infrastructure isolates the individual tenants from each other. The individual modules are containerized in Docker technology and orchestrated using Kubernetes. The proposed solution supports several interfaces between the module and the system. Supported interfaces include, for example, a standard client-server architecture or a standard input/output to allow the single-running of console applications.

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.

Web Page Archiving Tools
Kvačkaj, Matúš ; Rychlý, Marek (referee) ; Burget, Radek (advisor)
This bachelor thesis deals with the issue of archiving and reproduction of web pages. The aim was to provide a tool that, after specifying the URL and parameters, creates an archive in WARC format of a given page and also generates its textual description, suitable for further processing and analysis. The tool also supports the reverse process - replaying a site from a WARC archive and generating a textual description of the page. When implementing the tool, it was intended that it would be applied to an existing dataset and would be part of a bulk data processing. The Webis-Web-Archive-17 dataset was used, which contains approximately 10,000 WARC archives collected since 2017. To ensure maximum portability of the tool, Docker containerization was used.

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.

Secure data archiving using cloud computing
Šulič, Martin ; Sikora, Marek (referee) ; Člupek, Vlastimil (advisor)
This master’s thesis is focused on detailed analysis of possibilities of implementing a private cloud and secure data archiving for a long period of time using open-source tools. It describes the individual standards and processes of data preparation, as well as the OAIS reference model for long-term preservation. From the analyzed information, a complete design of the final solution is created, with a description of the functionality and the method of deployment in the environment of Docker containers. The design implementation and the main functionality of individual systems such as Archivematica or Nextcloud are thoroughly described and also the hardware requirements and cryptographic security were evaluated.
