Regarding MS information, information about each of a plurality of MS's includes meta information of the relevant MS. Regarding model information, information about each of one or a plurality of models includes meta information of the relevant model. A system evaluates appropriateness of an evaluation destination MS/model for an evaluation source MS/model as a replacement MS/model for the evaluation source MS/model on the basis of the meta information of the evaluation destination MS/model and the meta information of the evaluation source MS/model. The system recommends one or more evaluation destination MS's/models, as a candidate for a replacement MS/model of a designated MS/model, to a user on the basis of evaluation of each of one or two or more evaluation destination MS's/models regarding which the MS/model designated by the user in an application configured from one or two or more MS's/models is the evaluation source MS/model.

The authentication and authorization system includes an application execution unit, a user information storage unit, a token acquisition unit configured to acquire, using the user information acquired from the user information storage unit, an access token from an authorization server that authorizes the application to use the external service when a valid access token is presented via the cooperation unit, and a token storage unit configured to store the acquired access token. The token acquisition unit acquires the access token from the authorization server at a predetermined cycle, and stores it in the token storage unit. When the application uses the external service, the application execution unit requests a cooperation unit to make the application cooperate with the external service using the access token acquired from the token storage unit.

When flow data of flow is to be downloaded from a flow template manager to a flow editor, a system receives a first request to deploy an external service corresponding to an invoke node in the flow, and transmits a second request to deploy an external service identified by the first request to a service deployment manager associated with a site corresponding to the external service. The service deployment manager deploys an external service identified by the second request on a service execution platform at the site, and returns a response associated with an invocation destination end point corresponding to the external service. The system returns a first response associated with an invocation destination end point set to a property of the invoke node by the flow template manager to a transmission source of the first request.

Provided is an application development support system and method that support studies on applying serverless while optimizing application resource usage amount and maintaining API response performance in developing an application with microservices. In the application development support system, a container runtime platform applies serverless to a certain container to form an event-driven container. The application development support system executes an API processing time prediction process by calculating a predicted value of API processing time in the event-driven container and a predicted value of API processing time in all of the containers based on the predicted value and a sequence of API calls among the plurality of containers; calculating a usage amount of resources used by the plurality of containers per unit period; and outputting a calculated result of each of the API processing time prediction processing and the resource usage amount calculation processing.

Status information including remaining battery power is collected from a management target device. Subsequent operations of the device are identified from an operation schedule management collection. Battery consumptions corresponding to subsequent operations of the device are estimated from KPI management collection that includes information representing relationships between battery consumptions and operations with respect to each of a plurality of devices. The battery life of the device is predicted based on the estimated battery consumptions and the remaining battery power represented by the collected status information. A circuit schedule of a maintenance engineer is determined based on the predicted battery life, the schedule including necessity of dispatch of the maintenance engineer to the device.

Energy saving device management method and energy saving device management system

Example implementations described herein are directed to replication of data between different environments selectively while maintaining the performance of applications. The replication of data may be used to replicate data from a data center running a business critical application to another data center running an analytics application. In example implementations, a storage management program translates the IDs of database tables to storage locations, and the storage management program requests a storage system to replicate those storage locations to another storage system.

Method and apparatus for replicating data between storage systems

A service cooperation support system transmits a creation request concerning an external service to a service management system having a creation function concerning the external service, when a flow on a flow editing screen includes a service using node, and a user request for connecting the external service to the service using node is detected, and the system acquires, from the service management system, connection information (information created by the service management system) for connection to the external service created by the service management system in response to the creation request. The service cooperation support system sets the acquired connection information in the property of the service using node.
