Cost and Risk Aware Support for Cloud SLAs

Ming Jiang, Tom Kirkham, James Byrne, Karsten Molka, Django Armstrong, Karim Djemame, Ming Jiang, Tom Kirkham


Automated control of Cloud Service Level Agreements (SLA) is typically focused on Quality of Service (QoS) management and monitoring of the Cloud Infrastructure in-line with the SLA. Using risk assessments to bridge the needs of the Service Provider and Infrastructure Provider is one way in which the management of the whole Cloud SLA life-cycle can be achieved automatically. In this paper we adapt the QoS based risk approach and combine it with business orientated goal monitoring to improve the business input into the management of SLA from both a Cloud IP and SP perspective. We demonstrate this approach using probability of failure QoS risk linked to economic modelling of cost from the business goals of a SP.
