A novel method for scheduling workflows in cloud computing environment
G. Narendrababu Reddy, S. Phanikumar · 2017
The new and emerging IT paradigm, Cloud computing provides different options to customers to compute the tasks' based on their choice and preference. Cloud systems provide services to customers as a utility. The customers are interested in the availability of service at low cost and minimization of task completion time. The performance of cloud systems depends on efficient scheduling of tasks. The groups of tasks which are interdependent are referred as workflows. Workflow tasks scheduling plays an important role in estimating cloud system performance. If we want to minimize the task execution time (make span), the cost involved in it will increase. Here we proposed a novel scheduling method which minimizes the cost and time to schedule tasks of workflows. This algorithm schedules the tasks of a workflow to complete the execution in shortest feasible time so as to minimize the price for the services provided to customers. The experimental results show that proposed method minimizes the makespan and price in scheduling workflows when compared with other existing algorithms.
