Reward-based admission controller for resource requests in the cloud
Technology for selecting job characteristics to determine the similarity among jobs in terms of performance. Technology based on similarity among jobs calculated by selected characteristics for determining jobs that are likely to lead to successful performance of a requested new job by a cloud. Also, technology based on similarity among jobs calculated by selected characteristics for determining jobs that are likely to lead to failure when performing a requested new job by the cloud. When the new job request is accepted, because its characteristics of the new job matches job characteristics characterized by success and/or fails to match job characteristics characterized by failure, then the new job is said to lead to a “reward” or an “expected reward” because the new job will be rewarded by being allowed to use, by an admission controller of a cloud management system, use of cloud computing resources of the cloud.
1. A computer implemented method (CIM) comprising:
receiving a first new job request data set including information indicative of a first new job being requested to be performed by a cloud managed by a cloud management system;
determining, by an admission controller of the cloud management system, that performance of the first new job by the cloud would cause failures that are not reflected in monitored parameters but are indicated by job characteristics; and
responsive to the determination that performance of the first job with characteristics that are similar to historical jobs that failed, rejecting, by the admission controller, the first new job request.
2. The CIM of claim 1 further comprising:
receiving a second new job request data set including information indicative of a second new job being requested to be performed by a cloud managed by a cloud management system;
determining, by the admission controller, that performance of the second new job by the cloud would not cause any of the following three thresholds to be exceeded: the stack limit threshold, the process identifiers threshold, and/or the file handlers threshold; and
responsive to the determination that performance of the second new job would cause none of the thresholds to be exceeded, accepting, by the admission controller, the second new job request.
3. The CIM of claim 2 further comprising:
responsive to the acceptance of the second new job request, performing the second new job by the cloud.
