Bespoke Virtual Machine Orchestrator: An Approach for Constructing and Reconfiguring Bespoke Virtual Machine in Private Cloud Environment

A cloud-computing company or user needs to create a virtual machine to build and operate a cloud environment. With the growth of cloud computing, it is necessary to build virtual machines that reflect the needs of companies and users. In this paper, we propose a Bespoke Virtual Machine Orchestrator (BVMO) as a method of constructing a virtual machine. The BVMO builds resource volumes as core assets to meet user requirements and builds virtual machines by reusing and combining these resource volumes. This can increase the reusability and flexibility of virtual machine construction. A case study was conducted to build a virtual machine by applying the proposed BVMO to an actual OpenStack cloud platform, and it was confirmed that the construction time of the virtual machine was reduced compared with that of the existing method.
