The main benefit of IaaS (Infrastructure-as-a-Service clouds) is facilitate the users to retrieve their resources on demand. But, to afford on-demand access, cloud centers must either drastically abundance their infrastructure (and pay a high price for operating resources with low utilization) or reject a large proportion of user requests (in which case the access is no longer on-demand). Several models, applications and workflows are implemented for recovering the resources where interruptions in service are predictable. For instance, many researchers and scientists utilize HTC (High Throughput Computing) enabled resources, such as Condor, where jobs are dispatched to available resources and terminated when the resource is no longer available.
