Virtual-machine dynamic allocation system and server

Abstract

A virtual-machine dynamic allocation system and a server are provided. A slave server with an optimal response time with respect to a program can be selected from slave servers located near a client. The virtual-machine dynamic allocation system in which a master server dynamically allocates a virtual machine that is to execute a requested program to any one of slave servers, includes: a response-measurement-time-information measuring unit configured to measure response-time information about a period between transmission of a request signal from each slave server to each of programs operating in the master server and reception of a response signal from each program in the master server; a response-time-information storage unit configured to store the measured response-time information of each program for each slave server; and a slave-server determining unit configured to refer to the response-time-information storage unit so as to determine a slave server that is to execute the requested program.

Description

technical field [0001] The present invention relates to a virtual machine dynamic configuration system and a server, and is applicable, for example, to a virtual machine dynamic configuration system that operates a program (for example, an application program) on a distributed network. Background technique [0002] In recent years, with the development of network technology and computer technology, so-called cloud computing technology has also improved. [0003] Cloud computing deploys general computer servers (hereinafter referred to as "servers") at various stations, the server on the cloud acquires input data from the client, the server operates the application for the client, and the server sends the output via the communication environment Data is returned to the client. [0004] The cloud environment is utilized by many users. Since the scale of the cloud environment is large-scale, the same servers are arranged in many locations around the world. Therefore, which s...

Problems solved by technology

[0012] However, in an environment where the client can connect to multiple slave servers in physical proximity, there is a problem regarding which slave server should execute the application operation.

For example, even when a slave server that is physically closer to the client executes an application operation, the response from the slave server may not necessarily be fast from the viewpoint of real-time performance.
