A Survey of Virtual machine migration, Optimal Resource Management and Challenges

Virtual machines (VMs) have become increasingly valuable for resource consolidation and management due to their efficient and secure containers, as well as their capability to offer desired execution environments for applications. The cloud is also becoming increasingly popular, which is hosted in large data centers. The vast majority of these large data centers use a virtualized server infrastructure, known as a virtual machine (VM), that is managed by a cloud infrastructure service such as an open stack or cloud stack, etc. Computing, storage, and communication resources are increasingly needed in large Cloud Data Centers (CDCs). With the growth of cloud environments, VM migration has become an important criterion to ensure Quality of Service (QoS), save energy, and reduce resource usage. This paper examines the merits, challenges, and resource management aspects of virtual machines migration. In addition to providing load balancing, online system maintenance, proactive fault tolerance, power management, and resource sharing, it also helps to manage system power consumption.
