A QoS Metric Approach for Web Service Pertinence for the Cloud

Background: Cloud computing is an emerging technology today and playing an important role in providing the services through the internet. Users get enormous benefits like high accessibility of available application resources, faster time to market, fast development, deployment, lower startup, operations cost and much more. Cloud offers utilizing the benefits through the web services. Objective: The degrading factors such as low Quality of Service, security factors, and less resource management in cloud lead to service suitability issue. In service-oriented computing, finding an efficient QoS based web service on the web is a 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: In the experimental setup, the suitability scores calculated with the essential non-functional quality of service attribute information are identified from the set of services. However, the verification process is 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.
