A data processing unit required for the data processing is started and a data processing unit not required for the data processing is stopped to change a part of the data processing settings or to add a new data processing setting without stopping the multi-stage data processing, and when the multi-stage data processing is executed, a rear-stage data processing unit reads the tag assigned in a front-stage data processing unit to discriminate the data processing unit that executes the data processing.

Data processing system and data processing method

Allocation of resources is performed in which the performance of the services of each tenant can be maximized in a multi-tenant environment in which a plurality of tenants exist in which a plurality of data processing functions operate. The computer system calculates a first allocated resource amount to be allocated to each tenant based on the requested resource amount requested by each data processing function of each tenant, and calculates the second allocated resource amount to be allocated to each data processing function of each tenant based on the requested resource amount that each data processing function of each tenant requests and the first allocated resource amount of each tenant, and allocates resources to each data processing function of each tenant based on the second allocated resource amount.

Computer system and resource allocation control method

A computer system is configured to: obtain, from each of a plurality of processing applications, a communication index for evaluating data transmission and reception performance of the each of the plurality of processing applications, the plurality of processing applications each being configured to: obtain data from a source object; execute predetermined processing on the data; and transmit a result of the processing to a destination object; calculate a link allowable value indicating processing performance of each of the plurality of processing applications based on the communication index; generate a transmission plan relating to an amount of data to be allocated to each of the plurality of processing applications based on the link allowable value; and control transmission of the data to each of the plurality of processing applications based on the transmission plan.

Computer system and data transmission control method

To select a storage device suitable for storing data necessary for operation of an application in a system accompanying a dynamic configuration change. A computer system includes: a device configured to execute a processing in accordance with an application; a storage device configured to store application data for operating the application; and a control system, in which the control system is configured to specify the storage device which is operating from the present and at the time of changing a configuration of the computer system based on configuration change schedule information for managing a change schedule of the configuration of the computer system, select the storage device to store the application data from the specified storage device, and arrange the application data in the selected storage device before the configuration of the computer system is changed.

Computer system and method for controlling arrangement of application data

A service deployment control system includes a machine management module, a network management module, a service management module and a service deployment destination determination module. The machine management module is configured to acquire information on an operation of the service providing computer. The network management module is configured to acquire information on cooperation among a plurality of services. The service management module is configured to manage a condition for a computer resource that is set to and required for each of the services. The service deployment destination determination module is configured to select a service providing computer satisfying the condition for the computer resource required for the service out of the information on the operation as a candidate of a deployment destination of the service, generate combinations of the candidates as deployment patterns, calculate a deployment cost for each of the deployment patterns, select one of the deployment patterns.
