Patent number: 11914988Abstract: A phase classification model of a cloud application deployment device calculates a feature vector for each time period from resource usage data for each time period when an application is executed, clusters the feature vectors for each time period, and validates a result of the clustering to determine which phase the feature vector belongs to. Validation between a feature vector of a new application and a feature vector belonging to a cluster of a known phase is performed, and it is determined whether each time period belongs to the known phase or an unknown phase on the basis of a degree of the validation. The resource usage of a computer node for each phase is inferred, and application deployment is performed on the basis of an inference result.Type: GrantFiled: August 24, 2022Date of Patent: February 27, 2024Assignee: HITACHI, LTD.Inventor: Yuji Saeki
