Downsizing of web server design using Raspberry Pi 3 single board computer platform

Information and communication infrastructure (ICT) systems, partially or fully dedicated to the operation of internet, on the side of internet service providers and the side of internet users as well as on the communication infrastructure, form a significant share of the total ICT infrastructure on the global scale. Consumption of energy is an important aspect of the operation of this infrastructure not only in absolute numbers but also in comparison with office and home electrical appliances in general. That is why the reduction of its energy consumption draws attention. Contribution of the work described in this paper is the design of innovative web server platform providing Web Content Management System (WCMS) services using Raspberry Pi Single Board Computer (SBC) platform. Solution brings positive effects not only from ecological but also economical and computer security perspective. It is possible to see described design as the certain form of the web server downsizing in terms of size, energy consumption, associated heat dissipation and the price of the hardware platform and also downsizing of the web server software and data storage requirements with preservation of positive user experience. There is brief design description of the webserver presented in the paper, followed by results of selected performance and energy consumption tests.
