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.

The thesis is focused on the introduction to issue of cloud computing and cloud computing services. The main objective is to categorization of services in accordance to several parameters, which tends as crucial factors of choosing cloud computing services. The conclusion is achieved by analyzing various cloud computing services and subsequent synthesis of the most important parameters. The results of this thesis are the definitions of relevant categories common for the distributed models of service. According to these a potential consumer may choose from provided cloud computing services. Individual categories are divided by their technological or organizational characteristics. The categories are further defined from the infrastructure-as-a-service model view. The thesis is divided into a theoretical and a practical part. While the theoretical part describes basic terminology, characteristics and division of models, the practical part is defined by three sections. The first section contains the definitions of the most important categories with given parameters of distribution models. In the second section, categories from the infrastructure-as-a-service view are defined. In the last section, an analysis of globally accessible services focused on the infrastructure-as-a-service is provided.
