Dynamic Scheduling in Real Time with Budget Constraints in Hybrid Clouds

In this paper we handle the problem of scheduling tasks in hybrid clouds for small companies which can spend only a fixed budget in order to handle specific situations where the demand is high and cannot be predicted. We describe a model with important characteristics for the resource utilization and we design an algorithm for scheduling tasks which are sent continuously for execution, optimizing the schedule for tasks with high priority and short deadline. We propose an architecture that meets the challenges encountered by small business in their systems for tasks scheduling. We describe the main components, Configuration Agent and Task Scheduler, and we analyze different test scenarios, proving the efficiency of the proposed strategy.
