Abstract
A migration control apparatus includes a processor configured to, acquire a first communication log regarding a first virtual machine when execution of migration of the first virtual machine is not completed in a specific time, perform calculation of a first response time of a first processing request to the first virtual machine, acquire a second communication log regarding the first virtual machine after lowering frequency of assignment of a computing resource to the first virtual machine to a first rate, perform calculation of a second response time of a second processing request to the first virtual machine, calculate a second rate to which the frequency of assignment of the computing resource is permitted to be lowered, after starting re-execution of the migration, perform calculation of a third rate of the frequency of assignment of the computing resource for completing the re-execution, and perform determination of whether to cease the re-execution.
