Abstract

Enhancements in technology always follow Consumer requirements. Consumer requires best of service with least possible mismatch and on time. Numerous applications available today are based on Web Services and Cloud Computing. Recently, there exist many Web Services with similar functional characteristics. Choosing “a-right” Service from group of similar Web Service is a complicated task for Service Consumer. In that case, Service Consumer can discover the required Web Service using non functional attributes of the Web Services such as QoS. Proposed layered architecture and Web Service-Cloud, i.e. WS-Cloud computing Framework synthesizes the non functional attributes that includes reliability, availability, response time, latency etc. The Service Consumer is projected to provide the QoS requirements as part of Service discovery query. This framework will discover and filter the Web Services form the cloud and rank them according to Service Consumer preferences to facilitate Service on time.

Summary

Introduction

Following the global economic recession, businesses are gradually looking for more innovative ways to cut technical costs while maximizing value, to acquire competitive hold on IT market. A Cloud is a large group of interconnected computers that extends beyond a single company or enterprise [1,2]. Such computing helps cloud customers to expand their local computing power onto the relatively infinite processing power of the Internet. Services provide strong interface for collection of operations being accessed on network. This architecture works with two main entities, the one who launches particular Service, the Service Provider and the one who consumes Service, the Service Consumer. Web Services share business logic, data and processes through a programmatic interface across a network.
