The prevalence of cloud computing environments and the ever increasing reliance of large organisations on computational resources has meant that service providers must operate at unprecedented scales and levels of efficiency. Dynamic Resource Allocation (DRA) policies have been shown to allow service providers to improve resource utilisation and operational efficiency in presence of unpredictable demands, hence maximising profitability. However, practical considerations, such as power and space, have led service providers to adopt rack based approaches to application servicing. This co-location of computation resources, and the associated common provision of utilities it encourages, has immediate implications for system dependability.
