Abstract:Background: In cloud computing era, large scale scientific applications process large
amount of data in the data centers. Placing of this data onto a data center is a critical issue performed
as part of workflow management system and aims to find the best data center to place
the data. It has a direct impact on performance, cost and execution time of workflows
Method: In this paper, a novel data placement strategy is proposed based on crow search algorithm
(CSA) that dynamically distributes the data sets to appropriate data centers during runtime
stage of workflow
Results: The results obtained b y CSA based run time data placement algorithm are evaluated
with the results of other algorithms. Simulation results acknowledge that using CSA based data
placement algorithm provides appropriate results in comparison to the other algorithms.
