GreenWeb: Hosting High-Load Websites Using Low-Power Servers
Brad Everman, Ziliang Zong · 2018
Today, there are millions of web servers hosting billions of websites. To ensure quality of service (QoS), it has become conventional wisdom that websites, especially high-load websites, must be deployed on high-end servers. In fact, most of these costly servers are energy-hungry and vastly underutilized, thereby wasting significant amounts of energy and dollars. This paper explores the viability of using low-power commodity servers to host high-load websites while still maintaining comparable QoS. We demonstrate that, with certain software optimization (e.g. caching and content delivery network - CDN) enabled, low-power servers are able to host high-load websites without degrading the quality of web services.
