Abstract: In an information processing apparatus for managing a system including apparatuses classified into clusters, an acquiring unit acquires history records from a memory unit based on scheduled change information indicating a scheduled change in configuration information of apparatuses accounting for a first rate amongst apparatuses belonging to a particular cluster. Each history record includes content related to a change in the configuration information of at least one or more apparatuses amongst apparatuses belonging to the same cluster. The acquiring unit acquires, from the memory unit, history records each associated with a change in the configuration information of apparatuses accounting for a second rate amongst apparatuses belonging to the same cluster. The second rate satisfies a predetermined similarity relationship with the first rate. A predicting unit predicts, based on the acquired history records, an impact on the system due to implementing the scheduled change.

Abstract: A management device includes a memory and a processor coupled to the memory. The processor executes a process including: acquiring, from a plurality of devices, group information indicating a management group used to manage the devices and setting information indicating a setting item and setting content that are set in each of the devices; extracting a setting item corresponding to setting content that is common to devices included in a same management group indicated by the acquired group information; and creating, for the extracted setting item, a rule indicating that a common setting content is set to the devices included in the same management group.

Abstract: A resource control system includes a control unit configured to control to make hardware resources which are allocated to a virtual server increase if an extent of deterioration of response characteristics to requests for processing to the virtual server becomes greater than a certain first extent, and configured to control to change the certain first extent to a smaller second extent of deterioration in accordance with an increase in frequency of access to the virtual server.
