Darshan P Upadhyay, Prashant V Chauhan · International Journal of Advances in Engineering and Management · 2025
Virtual Machine (VM) migration is a fundamental aspect of cloud computing infrastructure management, enabling efficient resource utilization, load balancing, fault tolerance, and high availability. The process of moving a running VM from one physical host to another, with minimal disruption to the services, is crucial for the dynamic allocation of resources in cloud environments. This paper explores the various techniques used in VM migration, analyzing their advantages, limitations, and suitability for different cloud computing scenarios. The study covers precopy and post-copy migration methods, live migration algorithms, migration techniques in distributed systems, and hypervisor-assisted migration. Additionally, it identifies the challenges faced by cloud providers when implementing these techniques, and suggests areas for future improvements in VM migration technologies.
