Cloud computing governance a management from consumer point of view
Karkošková, Soňa ; Feuerlicht, Jiří (advisor) ; Hynek, Josef (referee) ; Voříšek, Jiří (referee)
Cloud computing brings widely recognized benefits as well as new challenges and risks resulting mainly from the fact that cloud service provider is an external third party that provides public cloud services in multi-tenancy model. At present, widely accepted IT governance frameworks lack focus on cloud computing governance and do not fully address the requirements of cloud computing from cloud consumer viewpoint. Given the absence of any comprehensive cloud computing governance and management framework, this doctoral dissertation thesis focuses on specific aspects of cloud service governance and management from consumer perspective. The main aim of doctoral dissertation thesis is the design of methodological framework for cloud service governance and management (Cloud computing governance and management) from consumer point of view. Cloud consumer is considered as a medium or large-sized enterprise that uses services in public cloud computing model, which are offered and delivered by cloud service provider. Theoretical part of this doctoral dissertation thesis identifies the main theoretical concepts of IT governance, IT management and cloud computing (chapter 2). Analytical part of this doctoral dissertation thesis reviews the literature dealing with specifics of cloud services utilization and their impact on IT governance and IT management, cloud computing governance and cloud computing management (chapter 3). Further, existing IT governance and IT management frameworks (SOA Governance, COBIT, ITIL and MBI) were analysed and evaluated in terms of the use of cloud services from cloud consumer perspective (chapter 4). Scientific research was based on Design Science Research Methodology with intention to design and evaluate artifact methodological framework. The main part of this doctoral dissertation thesis proposes methodical framework Cloud computing governance and management based on SOA Governance, COBIT 5 and ITIL 2011 (chapter 5, 6 and 7). Verification of proposed methodical framework Cloud computing governance and management from cloud consumer perspective was based on scientific method of case study (chapter 8). The main objective of the case study was to evaluate and verify proposed methodical framework Cloud computing governance and management in a real business environment. The main contribution of this doctoral dissertation thesis is both the use of existing knowledge, approaches and methodologies in area of IT governance and IT management to design methodical framework Cloud computing governance and management and the extension of Management of Business Informatics (MBI) framework by a set of new tasks containing procedures and recommendations relating to adoption and utilization of cloud computing services.

SOA and cloud computing
Křepela, Josef ; Karkošková, Soňa (advisor) ; Feuerlicht, Jiří (referee)
The primal goal of the bachelor thesis is describe principles of cloud computing, properties of SOA (service oriented architecture), their synergy following SOA Governance. At the beginning theoretical part will be described some important concepts and principles of cloud computing, there will be described deployment models and service models, SWOT analysis. In the next chapter is analyzed service oriented architecture. The third chapter describe the common features of cloud computing and SOA, synergy. The last chapter deals with governance of SOA (SOA Governance). Practical part of the work is modeling of SOA governing processes continuity with service cloud provider.

Protection against DDoS attacks in the cloud computing
Vavroch, Zdeněk ; Karkošková, Soňa (advisor) ; Jelínek, Ivan (referee)
DDoS Attacks are nowadays huge threat on the internet. Many people and companies are dependent on accessibility of their data, services or applications. And that is what attackers try to abuse. In some cases, site or application that is not working, can make very bad name for the company in public. DDoS attacks are dangerous for people working at home, for corporate networks and mainly for huge clouds. Cloud are often targets of attacks because of how many people are affected by it. This thesis is focused on types of DDoS attacks we know and goal of the thesis is to find best defense solutions, mainly for defending the cloud computing. I will choose and describe the most common methods we know and use. In theoretical part I will describe what is cloud computing and DDoS attacks and what types of DDoS we know. In practical part I will describe the most common and efficient methods of defense.

Usage of unstructured data in Business Intelligence
Rakhmanova, Malika ; Šperková, Lucie (advisor) ; Karkošková, Soňa (referee)
The aim of the thesis is to identify the main trends that are occurring in the market of Business Intelligence and related to unstructured data, to describe the possibilities for integrating unstructured data, to clarify what the impact on the company have the results that can be obtained using these solutions and how generally incorporate an analysis of unstructured data into BI. Another aim is to show the current situation of processing unstructured data on the example of BI system. The thesis is divided into several parts. First part is describing of the Business Intelligence area and the basic components of Business Intelligence, as well as identifying market trends. Then, there is the next part: separating the data into structured and unstructured. Here is the part about how you can access and analyse unstructured data and what is their place in BI systems. This is the end of a block of unstructured data and the beginning of a description of the enhanced version of BI. Finally, the current market situation and BI tools, which include unstructured data, are introduced. This section provides an overview of how BI tools approach to analyse unstructured data. Existed literature, professional and freely available Internet resources are used for writing the work. The purpose is to serve as a source of information for quickly orienting in the current situation, to serve as a guide to the world of BI solutions and to show potential users what are the options and functionality of these BI solutions.

Evaluation of the quality of IT services through the analysis of unstructured data
Zimmermann, Radim ; Vencovský, Filip (advisor) ; Karkošková, Soňa (referee)
The aim of this work is to obtain and analyze unstructured data from Web sites ( http://www.ispreview.co.uk ) ISPs in the UK using the analytical program KNIME Analytics Platform. In the first 7 chapters I described the theoretical tools that enable me to attain my goals . In the practical part I downloaded the data using a Web crawler, and then I analyzed the indexed search keywords and compare the two providers from the customer's perspective. The results were visualized using graphs and describe it . Contribution of my work is in the form of feedback or reports for business executives .

Fog computing
Poplštein, Karel ; Karkošková, Soňa (advisor) ; Feuerlicht, Jiří (referee)
The purpose of this bachelor's thesis is to address fog computing technology, that emerged as a possible solution for the internet of things requirements and aims to lower latency and network bandwidth by moving a substantial part of computing operation to the network edge. The thesis identifies advantages as well as potential threats and analyses the possible solutions to these problems, proceeding to comparison of cloud and fog computing and specifying areas of use for both of them. Finally, it examines the perspective of fog computing technology and its possible future development.

Karkošková, Soňa ; Mervart, Michal (advisor) ; Lafata, Pavel (referee)
Master thesis "Impact of Cloud Computing on Supply Chain Management" analyses the provisioning of IT resources in the form of cloud computing services and their impact on supply chain management environment. Attention is focused particularly on providing SaaS model of public applications delivery. The Cloud SCM implementation offers many advantages especially for small and medium sized companies. In this thesis I analysed the specifics of the deployment of Cloud SCM in highly unstable market environment, where a number of business partners share with each other relatively large amount of information. I identified factors of cloud computing, which have a significant impact on supply chain management. At the end of this thesis I analysed the trends of market supply, determined the leading providers of Cloud SCM and identified the specifics of selecting a suitable provider.
