2. Virtual machine migration. Virtualization can be important for cloud com -puting by enabling virtual machine migration to balance the load throughout the
data center. Virtual machine (VM) migration enables robust and highly responsive provisioning in data centers. As a result, it can be concluded that the
major benefit of VM migration is to avoid hotspots; however, this is not straightforward. Currently, detecting workload hotspots and initiating a
