The Evaluation of Virtualization Platform

The diploma thesis focuses on building a system, capable of hosting multiple services, primary e-mail, database and web server. Main goal in achieving such system were low development and maintenance costs, while keeping security on a high level. Due to estensive choice of free software available, such system was successfully built using virtualization technology. VMware's solution ESXi was used on a physical server, which hosted multiple virtualized servers. Security and routing is handled by Vyatta system, while user services are maintained by two servers using Ubuntu operating system. While establishing all those versions of Linux system (or based on its kernel), following best practises were not neglected. Security, performance in functional tests performed after completion of project were successfully executed, thus proving efficiency of virtualization environment. There has not been any expense for software and the system keeps low running and maintenance costs
