Data Persistence Storage in VMs Cloud-Based Software

Abstract

The virtual machine data persistence storage method in a cloud environment addresses the challenge of persistent storage for user data in cloud computing systems. This paper proposes a system and method that enables the creation and expansion of block devices for virtual machines. The method involves a major node receiving user requests, determining whether it is a block device creation or expansion request, and executing the appropriate steps. The major node interacts with storage nodes to create logical volumes and register them as block device services. By implementing this method, the issue of non-persistent storage for user data after virtual machine shutdown is effectively resolved. This paper presents a detailed description of the method, its background, research objectives, and a conclusion highlighting the significance and benefits of the proposed virtual machine data persistence storage system.
