Patent number: 11579933Abstract: A method for establishing system resource prediction and resource management model through multi-layer correlations is provided. The method builds an estimation model by analyzing the relationship between a main application workload, resource usage of the main application, and resource usage of sub-application resources and prepares in advance the specific resources to meet future requirements. This multi-layer analysis, prediction, and management method is different from the prior arts, which only focus on single-level estimation and resource deployment. The present invention can utilize more interactive relationships at different layers to effectively perform predictions, thereby achieving the advantage of reducing hidden resource management costs when operating application services.Type: GrantFiled: April 21, 2020Date of Patent: February 14, 2023Assignee: ProphetStor Data Services, Inc.Inventors: Wen-Shyen Chen, Wan-Chi Chang
