ON-DEMAND INTEGRATED CAPACITY AND RELIABILITY SERVICE LEVEL AGREEMENT LICENSING

摘要

A system and method for providing on-demand Integrated capacity and reliability Service Level Agreement (SLA) Software License (ISL). The disclosed approach allows customized purchase of capacity together with the desired reliability SLA at fine granularity of both quantities. The ISL licensing approach can be applied in the distributed Processing Entities (PEs) systems and also in the Virtual Machines (VMs) based cloud computing model. The on-demand ISL licensing approach makes use of an ISL dimensioning methodology (implemented using an ISL Manager) and an ISL Controller (ISLC) that keeps track of the capacity usage at the system level together with the periodic monitoring of health status of PEs or VMs. The ISLC dynamically controls the capacity usage as well as the reliability SLA based on the aggregated workload utilization conditions from all the PEs or VMs, hence allowing the delivery of the user-purchased level of guaranteed reliability SLA in an economical manner.
