Virtual machine migration is a fundamental capability in cloud computing that enables the transfer of an active virtual machine from one physical host to another with minimal or no service interruption. It is widely used to support resource optimization, load balancing, fault tolerance, and system maintenance in virtualized environments.
By allowing workloads to be dynamically relocated, VM migration ensures continuous availability and efficient infrastructure utilization. Techniques such as live migration further enhance this process by maintaining application uptime during transfer.
This blog provides a comprehensive overview of virtual machine migration, including its importance, types, working principles, live migration methods, as well as its benefits and challenges in cloud computing.
