    Designing Energy Efficient Virtualized Web Servers
    (CERIST, 2013-06) Chait, Khaled; Nouali, Omar
    There’s actually a kind of Moore’s Law for the Internet, which states that the Internet doubles in size every 5 years. About 2.4 billion of Internet users were registered worldwide in 2012. Having more users increases the need for more and larger data processing centers with thousands of servers. One consequence is the excessive energy consumption caused by web servers, which run web applications and web- based services. We propose a short study of energy consumption in relation to web server performance. We also propose a methodology to design energy efficient web systems using virtualization technologies.

    Research Line on Improving Energy Efficiency in Web Servers
    (CERIST, 2013) Chait, Khaled; Nouali, Omar; Juiz, Carlos
    This year the number of Internet users worldwide reached 2.27 billion, almost exactly twice what it was in 5 years ago, 1.15 billion. The increasing number of users, especially due to the popularization of web applications and web-based services, produces continuously capacity problems at data centers due to performance requirements. These web applications, which run on web servers, have an influence in energy consumption at data centers. Thus, a new challenge directly related to this area of research emerges: the energy efficiency of web systems. Additionally, new server virtualization technologies are appearing and have significant benefits in terms of hardware utilization, energy efficiency and configuration flexibility for its performance. We propose a short study of energy consumption in relation to web server virtualization and performance.
