Abstract
Cloud computing has emerged as a new style of computing in distributed environment. An efficient and dependable Workflow Scheduling is crucial for achieving high performance and incorporating with enterprise systems. As an effective security services aggregation methodology, Trust Work-flow Technology (TWT) has been used to construct composite services. However, in cloud environment, the existing closed network services are maintained and functioned by third-party organizations or enterprises. Therefore service-oriented trust strategies must be considered in workflow scheduling. TWFS related algorithms consist of trust policies and strategies to overcome the threats of the application with heuristic workflow scheduling. As a significance of this work, trust based Meta heuristic workflow scheduling (TMWS) is proposed. The TMWS algorithm will improve the efficiency and reliability of the operation in the cloud system and the results show that the TMWS approach is effective and feasible.
Highlights
In recent years the resources can be accessed from anywhere at any time through Internet without any burden
The time and cost factors are same as Workflow Scheduling (WFS) and the trust is based on the objective related to direct and recommended trust [12]
Trust Based Meta-Heuristics Workflow Scheduling (TMWS) Model In Section 4, the scheduling of workflow application system is defined with the trust based Meta heuristic workflow scheduling (TMWS) model to improve the performance analysis of strategies like time, trust and cost based on resources availability in cloud environment
Summary
In recent years the resources can be accessed from anywhere at any time through Internet without any burden. (2016) Trust Based Meta-Heuristics Workflow Scheduling in Cloud Service Environment. In parallel and distributed systems, scheduling of task is a challenging one It is based on trust accuracy and the resource status. In commercial multi-cloud environment the workflow scheduling is reported using mechanism design. Trust service oriented workflow scheduling (TWFS) is a trust based scheduling to allocate work flow task to the cloud services. Trust between providers is essential and TWFS model will optimize the trust It is an NP-hard problem and it has some policies to balance the requirement at a time in the cloud environment. The strategies of scheduling in enterprise system are developed to optimize the trust factors, cost and time, in order to specify the issues of TWFS and WFS model in a reliable way and to meet the integration necessities of ES.
