Abstract: A first storage apparatus determines whether to execute bulk requesting of causing a second storage apparatus to group a plurality of actual files corresponding to a plurality of stub files into one bulk data and transmit the bulk data. When determining to execute the bulk requesting in the determination, the first storage apparatus transmits a bulk request to the second storage apparatus. The second storage apparatus that has received the bulk request groups a plurality of actual files into one bulk data based on the bulk request, and transmits the bulk request to the first storage apparatus. The first storage apparatus that has received the bulk data extracts the plurality of actual files corresponding to a plurality of stub files, from the bulk data.

Abstract: The purpose of the present invention is, in a file storage, to shorten an access response time to shared data. When a file storage apparatus receives a command for a specific manipulation of a file system, a specific apparatus determines, based on a state of the file system and a manipulation history, whether or not an unapplied manipulation affects a target of the specific manipulation, the unapplied manipulation being a manipulation which has been previously executed by another file storage apparatus among a plurality of file storage apparatuses and which has not been applied to the file system. When it is determined that the unapplied manipulation affects the target of the specific manipulation, the file storage apparatus applies the unapplied manipulation to the file system, executes the specific manipulation on the file system, and transmits, to a cloud storage apparatus, manipulation information which represents the specific manipulation.

Abstract: A program creation assistance apparatus includes an arithmetic device that executes a flow data acquisition process for acquiring information of an execution target process and attribute information of the process, an environment determination process for determining an environment for executing the execution target process based on a predetermined rule that defines a relationship between a predetermined process and an environment for executing the predetermined process, and the acquired attribute information, and a registration process for transmitting, to the determined environment, information for executing a program that realizes the execution target process in the environment.
