MMO Plugin for Deployment of Microservices into the Cluster
Kulich, Jakub ; Beran, Vítězslav (referee) ; Herout, Adam (advisor)
Orchestration of applications with microservice architecture is difficult. Available tools do not allow deployment of an application to the user without deep knowledge of target platform. Another problem is that many mistakes are done when these tools are used. MMO - Monorepo Microservice Orchestrator is a tool that makes the development of applications with microservice architecture easier. MMO can be extended with parts that can help the user to avoid problems mentioned above. One part is used for generation of the configurations for deployment of the application to Kubernetes and second part is used for deployment of the application the Kubernetes cluster. A result of using MMO extension is an ability of beginner users to create deployment configurations, faster creation of deployment configurations by advanced users and decreased number of mistakes done when the application is deployed manually by Kubernetes users.

Memory Reduction of Stateful Network Traffic Processing
Hlaváček, Martin ; Puš, Viktor (referee) ; Kořenek, Jan (advisor)
This master thesis deals with the problems of memory reduction in the stateful network traffic processing. Its goal is to explore new possibilities of memory reduction during network processing. As an introduction this thesis provides motivation and reasons for need to search new method for the memory reduction. In the following part there are theoretical analyses of NetFlow technology and two basic methods which can in principle reduce memory demands of stateful processing. Later on, there is described the design and implementation of solution which contains the application of these two methods to NetFlow architecture. The final part of this work summarizes the main properties of this solution during interaction with real data.

Design and Implementation of SAP CAR with Automatic Disaster Recovery Function
Svitálek, Petr ; Dierzé, Lukáš (referee) ; Luhan, Jan (advisor)
The main purpose of this master's thesis is to propose and implement a SAP CAR (customer activity repository) solution as an application into the current enterprise information system. Following the analysis of the existing system, there will be a solution created, which is fulfilling the customer demands and at the same time it is feasible under given conditions and in the current environment. This project is closely related with addressing the disaster recovery issue for making the system highly available. The final design is implemented, tested and then handed over to the customer.

Asynchronous Task Processing in PCS Project
Pospíšil, Michal ; Pavela, Jiří (referee) ; Rogalewicz, Adam (advisor)
Projekt PCS je distribuovaná aplikácia. Z toho vyplýva, že potrebuje spôsob ako spúšťať akcie vo vzdialených inštanciách PCS. Cieľom tejto práce je vyvinúť minimálne životaschopné riešenie pre spúšťanie akcií cez REST API, ktoré je implementované metódami asynchrónneho programovania. Tieto akcie však nie sú implementované asynchrónne, takže nemôžu byť spustené priamo z asynchrónneho kódu. REST API je preto napojené na asynchrónny plánovač, ktorý obchádza toto obmedzenie spúšťaním akcií v sade procesov (process pool). Plánovač skrýva akcie za abstrakčnú vrstvu úloh, ktoré uchovávajú informácie o stave a výsledkoch akcií. Všetky akcie potrebujú posielať aktualizácie svojho stavu klientom v reálnom čase. Toto je dosiahnuté jednosmerným komunikačným kanálom medzi akciami a plánovačom, ktorý správy od akcií ukladá do úloh. REST API umožňuje vytváranie, kontrolu stavu a rušenie spracovania úloh. Klient teda môže opakovane žiadať o stav úlohy a takto zobrazovať aktualizácie stavu z akcií. Klient tiež môže zrušiť spracovanie úloh, ktoré bežia príliš dlho.

Cluster Solution for HA OpenVPN
Dokoupil, Jiří ; Kašpárek, Tomáš (referee) ; Halfar, Patrik (advisor)
The aim of this bachelor's thesis is to analyze the possibilities for running the OpenVPN daemon in a cluster and to implement such a solution. At first, the thesis analyzes current technologies and possible approaches to this matter. Next there's one possible solution described more and implemented. In the end there are results being analyzed, mostly by describing the tests, that took place with the implemented solution.

Study Statistics for Portal
Gruzová, Michaela ; Eysselt, Miloš (referee) ; Marušinec, Jaromír (advisor)
The master's thesis discusses the project and implementation of study statistics of the Portal of Brno University of Technology. It analyses the structure of the BUT portal and the technologies used for its creation. The technologies we are speaking about are the server-side scripting language PHP, query language SQL and cascading style sheets CSS. It describes the Oracle database technology and the st01 database scheme, a large scheme containing data used by information systems. It analyses the initial state of web applications and the situation at single faculties. The thesis analyses different solutions of certain parts of the application and studies the most appropriate ones. At the end it describes the implementation of study statistics and its integration into the central information system.

Cluster analysis of data traffic
Nagyová, Simona ; Martinásek, Zdeněk (referee) ; Blažek, Petr (advisor)
This thesis is meant to present the methods of cluster analysis, their use for detecting network traffic anomalies. It deals with various types of cyber attacks particularly DoS (DDoS) attacks. It contains a list of well-known DoS attacks. Also includes a program in Python, using the k-means method for detection of anomalous traffic.
