Abstract :
The disqualification of third-party cloud services has caused great threat to large-scale Enterprise Systems (ESs). Service Level Agreements (SLA) management is used to enhance Quality of Service (QoS) in an effective way. Conventional service exception handling is triggered to deal with functional failure. However, in some critical business scenario, service failures and performance violations need to be proactively prevented instead of recovery triggered by the occurrence of those failures. In this paper, a proactive detective control model is proposed to prevent workflow SLA violation supported by the utilization of SLA utility functions and control charts. Emulation case study illustrates the proposed model, and simulation results show that workflow SLA management can effectively avoid cloud services composition failures.
