Heuristic and meta-heuristic workflow scheduling algorithms in multi-cloud environments — A survey

Cloud computing recent emanation has drastically diversified everyone´s perception of software delivery, infrastructure architectures, application development and deployment models. It is a new touchstone preceding the enterprise application development that can effectively expedite and facilitate the execution of various workflows in business process management system. Workflow is an automation of a business entity that can manage the business processes efficiently satisfying the requirements of prevailing enterprises. Dynamic workflows in a cloud computing environment empower the utilization of various cloud services to facilitate workflow execution. Scheduling multiple workflows in cloud environment is always a challenge. Workflow scheduling is a critical issue in the management of workflow execution. In this paper, we have compared and analyzed the performance of different heuristic workflow scheduling algorithms with various QoS parameters and scheduling factors.
