SLA violation refers to the dissatisfaction of the conditions agreed on in the corresponding Service-Level Agreement (SLA).Flexible and reliable management of Service Level Agreements is of paramount importance for both service providers and consumers. The prevention of SLA violations ahead of time can avoid unnecessary penalties, a provider has to pay in case of violations. Sometimes, simple actions like migrating services to available nodes can prevent such violations. [Brandic et. al. 2010] [CD-JRA-2.3.4] {SPC: Service Level Agreements} |
