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. Since 2006 National ICT Australia Ltd (NICTA) has been developing a technology for the performance modelling of large scale heterogeneous Service Oriented Architectures (SOAs).
