Abstract: A storage system 103 carries out first and second de-duplication processes in response to receiving a write request from a client. First, a determination is made as to whether a write target data item overlaps with any of the stored data items of a part of a stored data item group, which is a user data item group stored in a storage device 209, and if so, the write target data item is prevented from being stored in the storage device. Second, a determination is made as to whether a target stored data item, which is not finished being evaluated as to whether it overlaps with the stored data item in the first de-duplication process, overlaps with another stored data item, and if so, the target stored data item or the same data item overlapping with the target stored data item is deleted from the storage device 209.

Abstract: A computer system is coupled to infrastructure systems each configured to implement an environment for providing resources to each of instances forming an application. The computer system is configured to: receive a deployment plan generation request for the application which includes a serverless instance for which, as an activation method, any one of a warm start and a cold start is selectable; generate, based on a resource amount required for the each of instances, an allocation pattern which is a combination of an environment of a deployment destination of the each of instances; generate an activation pattern which is a combination of the activation method for the each of instances; plan an activation timing of the serverless instance for the activation pattern; generate a plurality of deployment plans by combining the allocation pattern, the activation pattern, and the activation timing.

Abstract: A data sharing system and method eases the sharing of original data, including data to be modified before publication, by modifying the original data to generate publication data before publication and publishing the publication data. A profile including information of a data acquisition area from which the original data is acquired and a list of types of data included in the original data is generated. For each of the plurality of areas based on the profile, pre-publication modify processing information storing, in association with each other, the name of a pre-publication modify type of data to be modified before publication and the name of a modify processing for modifying the data of the pre-publication modify type is generated. Further, a public data disclosure unit is configured to generate public data obtained by modifying the original data by the modify processing based on the pre-publication modify processing information.

Abstract: A computer system for searching for a candidate for an environment in which an object is to be deployed, the computer system is coupled to a plurality of infrastructure systems each of which provides the environment. The computer system receives a search request including an environmental requirement being a condition required for the environment in which the object is to be deployed and a constraint being a condition to be complied with in deployment of the object; executes first environment search processing for searching for the environment that satisfies the constraint and the environmental requirement; changes the environmental requirement in a case where the environment in which the object is deployable does not exist; and executes second environment search processing for searching for the environment that satisfies the constraint and the changed environmental requirement.

Abstract: To derive a query which can be joined and which gives non-zero pieces of data even if joined. A query generation assist method to assist generation of a query to extract data from a database includes: a first step of accepting, at the computer, a condition of extracting data to be acquired from the database as a data extraction condition; a second step of extracting, as graph data and at the computer, data which can be joined in data of the database; a third step of extracting subgraphs at the computer based on the data extraction condition from the graph data, and acquiring the subgraphs as query candidates; and a fourth step of calculating, at the computer, rank values of the query candidates and outputting the query candidates ranked according to the rank values.

Abstract: In a computer system according to an embodiment of the present invention, a first slave server includes copy management information associating a master file system identifier with an identifier of a slave server including a copy of the master file system identified by the master file system identifier. The first slave server acquires a copy of a part of a master file system. The copy includes a stub-state object (file or directory). The first slave server searches the copy management information for a slave server to be queried regarding information for materializing the stub-state object. If the slave server to be queried includes the information for materialization, the first slave server materializes the stub-state object using the information for materialization acquired from the queried slave server.

Abstract: A file server stores storage management information and migration policy information. The storage management information includes information that indicates a storage attribute for each storage apparatus. The migration policy information includes a plurality of information sets. Each of the information sets includes information that indicates a condition of a file attribute and information that indicates a condition of a storage attribute of a storage apparatus that is a migration destination. The file server specifies a migration target file, specifies a storage apparatus that conforms to the storage attribute condition indicated by the information set that includes the information indicating a condition of a file attribute that conforms to that of a file attribute of a target file based on the storage management information, and migrates a target file from a storage apparatus that has stored the target file to the storage apparatus that has been specified.
