Data centre project - structured cabling
Hejtmánek, Ondřej ; Dostál, Otto (referee) ; Filka, Miloslav (advisor)
This master’s thesis is concerned with analysis of cabling and cabling systems in data center and with their projection as follows. The part of the work is aimed at the measurement parameters of metal cables which are used in data center with noise. The first part is focused on analyzing the structure of the data center and cabling used in it. The structure of the data center is based on the TIA-942 and consists of an entrance room, main distribution area MDA, horizontal distribution area HDA , zone distribution area ZDA and the equipment distribution area EDA. Divided into backbone cabling and horizontal cabling and use standard and pre-terminated cabling. The measurement results of structured metal cabling with noise are discussed in the next part. There were used these types of cables UTP, FTP and S/FTP. The measurement was performed in the electricity substation and in the laboratory of electromagnetic compatibility. The third part of this work deals with the actual design of structured cabling for the data center. In the first design we use the standard installation, the second preterminated cabling. For both types of installation cost statement is processed (CAPEX). Thesis is also completed with DC design drawings and rack drawings.

Methodology of optimal usage of load balancing in data center environment
Nidl, Michal ; Gála, Libor (advisor) ; Hořejš, Jan (referee)
The following master thesis is focused on creation of methodology for optimal usage of load balancing in data center environment. Thesis is divided into eight chapters. The first chapter describes the reasons why to deal with this topic further. The second chapter summarizes the state of load balancing. This chapter is based on research of already elaborated thesis which were focused on load balancing in different ways. The third chapter summarizes load balancing including its key principles. The fourth chapter describes an actual state of load balancing in data center environment. An observation of real usage of load balancing in selected data center was used for the main purpose of this chapter. The fifth chapter consists of analysis of the currently existing methodologies which are used from the infrastructure projects purpose. The sixth chapter deals with creation of methodology for optimal usage of load balancing in data center. The seventh chapter evaluates usage of methodology by applying of this methodology to real practical example of implementation of load balancing. The eighth chapter summarizes all detected conclusions.

Safe cloud infrastructure design
Hanzlová, Marie ; Pour, Jan (advisor) ; Pilin, Petr (referee)
This diploma thesis is focused on the security of cloud computing. Theoretical part of this thesis identifies options which generally lead to higher safety and availability of applications, regardless of the solution. A package of cloud services (called Productivity Suite) was defined, based on the customers' requirements, which is built on Microsoft platform and combined of the following products: Microsoft Exchange, Microsoft SharePoint, Microsoft Lync and is intended to be used by end customers. Specification of the service package, identified opportunities for strengthening the level of security and requirements of potential customers are the primary inputs for designing safe cloud infrastructure, which is the main contribution of this thesis. First step of designing infrastructure is to choose the service provider of data center, who will operate the solution. A decision must be made to select leased solution or owned components. The result of this part is a calculation, which contains all HW components (servers, firewalls, switches, tape library backups, disk arrays) and SW components considering the licensing policy, SSL certificate, domain, backup solution and other operating costs. The solution is limited by financial resources. The priority is safety, security and quality of services.

Price models and SLA for shared services of data centers
Štefek, Ivan ; Voříšek, Jiří (advisor) ; Bruckner, Tomáš (referee)
Thesis Price models and SLA for shared services of data centers has as objective to establish best practice, so-called "best practices" of SLA and price models for data center services. Work is divided into two parts, theoretical and practical part. The theoretical section is wants to familiarize the reader with the basic concepts such as outsourcing, reasons and risks of use. I describe the base models for providing IT services as well as pricing models for services as described in the literature. I will focus on data centers and TIER standard categorization, too. The practical part is based on an analysis of information that I got from an interview with the experts working for the biggest data center companies in the Czech Republic. Based on this information, I tried to compile the best practices for creating pricing models for data center services that are actually used in practice. Specifically, the server housing, server hosting and virtual server services. Also, for these services create an SLA that can be used by some data center company in the Czech Republic.

Cloud computing with regard to technological aspects and changes in infrastructure
Vítek, Daniel ; Donát, Jiří (advisor) ; Bruckner, Tomáš (referee)
This thesis discusses the new way of delivering IT services over the Internet widely known as cloud computing. In its opening part, cloud computing is put into a historical context of the evolution of enterprise computing, and the dominant issues the IT department faces today are mentioned. Further, the paper deals with several components that make up the architecture of cloud computing and reviews the benefits and drawbacks an enterprise can have while it adopts this new model. One of the primary aims of this thesis is to identify the impact of the technology trends on cloud computing. The thesis brings together four major computing trends, namely virtualization, multi-tenant architecture, service-oriented architecture and grid computing. Another aim is to focus on two trends related to IT infrastructure that will lead to fundamental changes in IT industry. The first of them is the emergence of extremely large-scale data centers at low cost locations, which can serve tremendous amount of customers and achieve considerable economies of scale. The second trend this paper points out is the shift from multi-purpose all-in-one computers into a wide range of mobile devices dedicated to a specific user's needs. The last aim of this thesis is to clarify the economic impact of cloud computing in terms of costs and changes in business models. The thesis concludes by evaluating the current adoption and predicting the future trend of cloud computing.

Project management: Data center migration
Šťastný, Jan ; Svatá, Vlasta (advisor) ; Pavlíček, Antonín (referee)
This thesis is trying to review project methodologies which could be used for a data center migration project. The aim of this work is to choose a project methodology for the migration project, based on the methodologies' description. On selected area of project management will be shown the differences between the most suitable methodologies and a practical example of the chosen methodology will be prepared.
