We consider the problem of opportunistically scheduling low-priority tasks onto underutilized computation resources in the cloud left by high-priority tasks. To avoid conflicts with high-priority tasks, the scheduler must suspend the low-priority tasks (causing \imp{waiting}), or move them to other underutilized servers (causing \imp{migration}), if the high-priority tasks resume. The goal of opportunistic...
