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.

Effects and problems of cloud computing
Hanzlová, Marie ; Pour, Jan (advisor) ; Kačmář, Dalibor (referee)
This thesis focuses on effects and problems from a customer perspective. The main objective of this work is to create a fair idea of cloud computing services. Fair idea means primarily effects, which can occur while using cloud services, but also effects to which entities must face before and after they decide to use these services. The main part of the work is devoted to the problems and effects of cloud preceding section which focuses on general information such as main idea, principle of operation and characteristics of cloud computing. This section includes characteristics of deployment and delivery models of cloud computing. The general information section is followed by chapters containing summary (operational, economic and personal) effects and problems. These issues mean both security issues and technical problems such as blackouts, legal aspects and other issues that should be considered before launching cloud computing services. This follow-up analysis shows the appropriateness of deploying cloud services in three specific environments. These are small companies whose main activity is not associated with an IT area. The interview was done in these companies and it was collected basic information about the company on core business and IT functions. Analysis was performed based on information and dismantled effects and problems in the theoretical part which shows mainly for selected businesses, whether it has a sense to deal with cloud computing services.
