Scale-out method and system

摘要

A scale-out method includes: upon detecting that a processing load of a first virtual machine among one or plural virtual machines exceeds a threshold, deploying a second virtual machine that is a new virtual machine; selecting a process that satisfies a predetermined condition based on processing loads of plural processes operating in the first virtual machine; first specifying first information for identifying first software related to selected process; and setting up the first software on the second virtual machine based on the first information.

1. A scale-out method, comprising:
upon detecting that a processing load of a first virtual machine among one or plural virtual machines exceeds a threshold, deploying, by one of plural computers, a second virtual machine that is a new virtual machine; selecting, by one of the plural computers, a process that satisfies a predetermined condition based on maximum or total processing loads of plural processes operating in the first virtual machine; first specifying, by one of the plural computers, a first program that includes an instruction for installing first software related to the selected process and an instruction for performing initial setting of the first software; second specifying, by one of the plural computers, a second program that includes an instruction for installing second software which has a first predetermined relationship with the first software and an instruction for performing initial setting of the second software, wherein the first predetermined relationship is a relationship in which the first software is executed in a case where the second software is installed on a virtual machine on which the first software is simultaneously installed; first installing, by one of the plural computers in response to the first predetermined relationship being satisfied, the first software and the second software on the second virtual machine by the first program and the second program; and first performing, by one of the plural computers, the initial setting of the first software and the second software by the first program and the second program.
