A QoS Metric Approach for Web Service Pertinence for the Cloud

Abstract

Background: Cloud computing is a very emerging technology today and playing an important role to provide the services through internet. Users are getting enormous benefits like high accessability of available application resources, faster time to market, fast development, deployment, lower start-up, operations cost and much more. Cloud offers us to utilize the benefits through web services. Objective: The degrading factors such as low Quality of Service, security factors, trustless and less resource management in cloud leads to service suitability issue. In service oriented computing finding an efficient QoS based web service on the web is very challenging task. Methods: A quality of service metric approach is proposed to identify the suitability of web services and ensuring the deployability in the cloud era. The suitability of web service is examined for its suitability cases (simple suitable, average suitable and best suitable) with respect to the quality of service attribute. Results: The experimental setup, first the suitability scores calculated with the essential non-functional quality of service attribute information is identified from the set of services. However, the verification process expressed using the state transition diagram. Conclusion: The proposed system is simulated using JFLAP-a java package tool and the result shows the service suitability for the cloud. In this context the efficiency of identifying service suitability for deploying in the cloud gets verified using automated theory without affecting the performance of the cloud service.
