The analysis of modern cloud solutions
Kis, Matej ; Burda, Karel (referee) ; Rosenberg, Martin (advisor)
This thesis describes existing cloud storage systems. Description of the prerequisites of developing cloud and distributed systems are presented. Current storage systems such as Dropbox, iCloud and Google drive are described. Description is mainly focused on the resources of both protocols and derive a conclusion for the use in the cloud storage systems. The practical part of this work is focused on creating two labs, what will be implemented in the teaching syllabus of Projecting, Administration and Security of Computer Networks subject. The first of the labs is focused on the implementation of own cloud services. In the last lab students attention will concentrate on interception of communication secured with SSL protocol.

Dynamic resource balancing in virtualization clusters
Grafnetter, Michael ; Yaghob, Jakub (advisor) ; Děcký, Martin (referee)
The purpose of this thesis was to analyze the problem of resource load balancing in virtualization clusters. Another aim was to implement a pilot version of resource load balancer for the VMware vSphere Standard-based virtualization cluster. The thesis also inspected available commercial and open source resource load balancers and examined their usability and effectiveness. While designing the custom solution, a modification of the greedy algorithm has been chosen to be used to determine which virtual machines should be migrated and to select their target hosts. Furthermore, experiments have been conducted to determine some parameters for the algorithm. Finally, it was experimentally verified that the implemented solution can be applied to effectively balance virtualization server workloads by live migrating virtual machines running on these hosts.

Project management in cloud
Šťastný, Jan ; Svatá, Vlasta (advisor) ; Kalina, Jaroslav (referee)
Goal of this thesis is to provide a summary of information connected to cloud project management. The thesis describes, what cloud is, what types of cloud there are and also describes project management methodologies and their specifics. In the practical part of this thesis one of the methodologies is applied to a practical project. The thesis contains also a summary of practical information about cloud projects and risks associated with cloud projects.

Adoption of Cloud computing in the corporate sector
Malík, Tomáš ; Donát, Jiří (advisor) ; Koubský, Petr (referee)
This work is focused on the newly emerging field of Cloud computing and view of adoption of this technology in various industrial sectors. The first section explains the concept of cloud computing, its characteristics and individual models. The following part is a brief analysis of the size and development of the current market for cloud services. Next section focuses on the creation of industry categories acording to area of their business, together with their description. The actual categories are examined in part four, along with their expenditures on IT and state of Cloud's adoption, in addition with specific advantages and obstacles. Results from previous section are summarized in part five. In conclusion, the hypothesis is verified and the main findings summarized.

Providing ICT services in the cloud
Neumann, Jiří ; Voříšek, Jiří (advisor) ; Kopecký, Roman (referee)
This thesis focuses on the ubiquitous cloud computing trend and particularly Software as a Service. The main goal is to specify all pros and cons of this concept for its customers and also cloud providers. The global perspective is then specified to Software as a Service and deployment of SaaS ERP products. The next goal is to define an appropriate method to analyze a company's needs prior to switching to the cloud. Furthermore, recommendations as to whether the cloud is better than an on-premise version should result from the previous analysis. Another aim is to form a process for successful switch to the cloud and ensure all important aspects of using cloud services are covered. Theoretical findings and recommendations are used in a practical example of SaaS ERP deployment. To reach all goals, a theoretical analysis of all available monograph and electronic sources, covering cloud computing and consultations with experts from the company; Algotech BSC, were used. The main added value is in the dual point of view on the topic, from customer's and provider's viewpoints with a more detailed focus on ERP. The author suggests the right procedure for switching to the cloud, guidance with calculating ROI, TCO and preparing all necessary contracts and agreements.
