the The Issue of Live Migration of Virtual Machines

Abstract

Virtualization technologies are commonly used in today's data centres for a variety of reasons, including economic, security, and technical benefits. One of the key advantages of virtualization is the ability to live to migrate virtual machines (VMs) from one physical machine to another over a network infrastructure. This process allows for the seamless transfer of data, processing, and network addresses from one hardware platform to another without causing any disruption or delay to user services. However, when transitioning from a local area network (LAN) to a wide area network (WAN), complexities pose challenges in achieving desired objectives. These challenges can be caused by factors such as network latency, bandwidth constraints, and VM size. This article provides an overview of the concepts, constraints, and existing methods to address these challenges. Furthermore, this field presents novel and valuable opportunities for conducting research projects, some of which have been briefly mentioned.
