| Summary: | Faculty of Teaching and Education Science ( FKIP ) UNS , as one unit at the Universitas Sebelas Maret, have some information systems for electric data proccesing. This information system was entrusted to their ICT Center whose have responsible under the FKIP bureaucracy. The needs for information systems applications is increasing, but the growth of the information system is not proportional to the availability of existing server hardware. We need a solution to overcome the limitations of hardware resources in FKIP UNS. In this research, we use hypervisor virtualization to overcome limitations of server hardware, hypervisor virtualization choosen because it has a lower overhead and better performance than other types of virtualization. While the hypervisor software is using Proxmox VE. In this research, we tested the performance of the web server, then we compare its with other environment (eg: physical web server and virtualized web server). In order to deliver the same configuration and fair result, before the performance comparison we replicate the web servers from physical servers to virtual servers. The results of performance measurements on this web server interpreted that web server that runs in a virtualized environment is still able to serve users as well as web server running on the physical environment. Some statistics show a decrease in performance, but the performance degradation is still acceptable because the average performance degradation is only 7.8 % than web server running on physical environment. In addition, the ICT Center FKIP UNS financing will save server and network devices by as much as 48.11% and 35.134% when using virtualization in the data center infrastructure.
