Performance modelling power consumption and carbon emissions for Server Virtualization of Service Oriented Architectures (SOAs)

Abstract

Server Virtualization is driven by the goal of reducing the total number of physical servers in an organisation by consolidating multiple applications on shared servers. Expected benefits include more efficient server utilisation, and a decrease in green house gas emissions. However, Service Oriented Architectures combined with Server Virtualization may significantly increase risks such as saturation and Service Level Agreement (SLA) violations.
