Query: Scheduling Bag-of-Tasks in Clouds using Spot and Burstable Virtual
  Machines   Leading Cloud providers offer several types of Virtual Machines (VMs) in
diverse contract models, with different guarantees in terms of availability and
reliability. Among them, the most popular contract models are the on-demand and
the spot models. In the former, on-demand VMs are allocated for a fixed cost
per time unit, and their availability is ensured during the whole execution. On
the other hand, in the spot market, VMs are offered with a huge discount when
compared to the on-demand VMs, but their availability fluctuates according to
the cloud's current demand that can terminate or hibernate a spot VM at any
time. Furthermore, in order to cope with workload variations, cloud providers
have also introduced the concept of burstable VMs which are able to burst up
their respective baseline CPU performance during a limited period of time with
an up to 20% discount when compared to an equivalent non-burstable on-demand
VMs. In the current work, we present the Burst Hibernation-Aware Dynamic
Scheduler (Burst-HADS), a framework that schedules and executes tasks of
Bag-of-Tasks applications with deadline constraints by exploiting spot and
on-demand burstable VMs, aiming at minimizing both the monetary cost and the
execution time. Based on ILS metaheuristics, Burst-HADS defines an initial
scheduling map of tasks to VMs which can then be dynamically altered by
migrating tasks of a hibernated spot VM or by performing work-stealing when VMs
become idle. Performance results on Amazon EC2 cloud with different
applications show that, when compared to a solution that uses only regular
on-demand instances, Burst-HADS reduces the monetary cost of the execution and
meet the application deadline even in scenarios with high spot hibernation
rates. It also reduces the total execution time when compared to a solution
that uses only spot and non-burstable on-demand instances.
