Abstract: An environment construction support system includes a know-how accumulation unit that accumulates in a storage apparatus, know-how information about environment construction for an image that is a source of a container, and an environment construction support unit that on reception of an environment construction request with fragmentary environment construction information from a request source, acquires know-how information from the know-how accumulation unit, complements the fragmentary environment construction information, based on the know-how information to generate completed environment construction information.

Abstract: A system comprises an execution server, a control server and an IP storage. The execution server is equipped with an FPGA and creates a virtual machine which uses the FPGA as one of hardware resources. The control server controls the execution server. The IP storage stores an IP to be downloaded to the FPGA. The control server makes reference to a check sheet including information for associating at least an identifier of the virtual machine with an API used by the virtual machine and verifies the pertinency of a combination of the virtual machine and the IP which has been stored in the IP storage and to be downloaded to the FPGA.

Abstract: There is provided a resource optimization method enabling a stable live migration. An amount of generated traffic that is anticipated to be generated is estimated based on the number of subscribers to be processed by a SIP server on a virtual machine (step S1). Since it is not necessary to perform a live migration of the virtual machine when the estimated amount of generated traffic is less than or equal to an optimum value predetermined as throughput of physical hardware on which the virtual machine operates (“Yes” in step S2), monitoring of the number of number of subscribers is continued by returning to step S1. Meanwhile, when the estimated amount of generated traffic exceeds the optimum value (“No” in step S2), an optimum physical hardware which has a margin for processing the amount of generated traffic is selected, and the virtual machine live-migrates to the selected physical hardware (step S3).

Abstract: In a resource control device (150), a play setting control unit (154) transmits, to an OFC (170), flow information necessary for generating a flow entry corresponding to communication by a virtual machine (130), in parallel with issuance of an instruction to generate the virtual machine (130) by a generation instruction issuing unit (152). Upon receiving the flow information from the play setting control unit (154), the OFC (170) generates a flow entry based on the flow information and sets the flow entry to the OFS (160) that relays the communication by the virtual machine (130). Thus, in a network system in which OpenFlow control is performed, the time required to start provision of services by the virtual machine is shortened.
