Abstract: A computer system includes: a model generation system configured to generate a model using learning data; and a model management system configured to record model generation data created in accordance with users who use a prediction process based on the model in association with the users, group the users according to a prescribed grouping condition, and supply the model generation system with learning data including model generation data created in accordance with users belonging to the group and cause the model generation system to generate an integrated model corresponding to the group.

Abstract: A management computer manages first XaaS including a first node configuration and second XaaS including a second node configuration that is dependent on resources provided by the first XaaS. When a required resource amount which is required for the first XaaS in order to change the second node configuration is larger than a resource amount which can be provided by the first XaaS, the management computer determines a changed first node configuration which is capable of providing a resource amount equal to or larger than the required resource amount and, after changing the first XaaS to the determined changed first node configuration, changes the second node configuration of the second XaaS.

Abstract: In a system, such as a cloud, which allows resource allocation to be flexibly changed in a multi-tenant environment, it is necessary to interchange resources between the tenants. Efficient resource coordination for resource allocation cannot be attained by merely adjusting resource allocation amounts or resource usage amounts. In order to address this problem, the present invention selects an optimum allocation method from among a plurality of resource allocation methods including CPU capping, taking into account each period for which resources must be allocated and the manner in which each tenant uses resources, and then coordinates allocation of resources across the entire system using the selected allocation method. This makes it possible to improve the efficiency of resource coordination even in a multi-tenant environment.

Abstract: A management computer for managing a management target system comprises an operation situation evaluating part, an operation situation displaying part, an amelioration plan generating part, and an amelioration plan displaying part. The amelioration plan generating part identifies, as an amelioration plan, a business system configuration that ameliorates the operation situation of the business system that is in operation, based on operation situation value calculated by the operation situation evaluating part. The amelioration plan displaying part displays an operation situation that is expected in a case where a business system configuration identified by the amelioration plan generating part is applied, in association with the operation situation of the business system that is in operation.

Abstract: A management system has a topology display screen of a management target system with an area, where icons of system components are typically displayed in the related art, which is embedded and displayed with a graph of a monitor value of the system component. A band having a predetermined width is displayed to show a relation between system display objects indicating the system components. The width of the band is determined by the number of requests which are transmitted or received by the system components. When a time-sequential graph of the monitor value of a system component is displayed, a vertical bar which can be operated by an input/output device is displayed in the graph. When the operation of the vertical bar is detected, an icon indicating integrity of the management target system at a time indicated by the vertical bar is displayed in the vicinity of the vertical bar.

Abstract: A management apparatus comprises a processor configured to execute a program and a storage resource configured to store the program, wherein the processor executes: an identifying process configured to identify an another job having a scheduled execution period overlapping with a scheduled execution period of an estimation subject job among a plurality of jobs executed at a first server from the plurality of jobs; a calculating process configured to calculate an islanding execution time in which the estimation subject job is executed individually at the first server based on the scheduled execution period of the estimation subject job and the scheduled execution period of the another job identified in the identifying process and a creation process configured to create a schedule which correlates the estimation subject job with the islanding execution time calculated in the calculating process.
