Towards architecture model based deployment for dynamic grid services

The deployment of grid services should make the services, including those to be deployed and those already deployed, operate with desired functionalities and qualities. The critical challenge in the deployment is that many technical and nontechnical factors have to be taken into account, such as performance, reliability, utilization, operating cost, incomes, and so on. Since the factors change continuously, some deployed services may have to be redeployed for guaranteeing their functionalities and qualities. This position paper presents an approach to the deployment and redeployment of grid services based on software architecture models. In this approach, all services in a grid consist in a software architecture, which represents the services, their relationships and other factors in a global, understandable and easy-to-use way. To demonstrate the approach, a visual tool for deploying services onto a set of popular grid infrastructures, including J2EE application servers and BPEL engines, with the help of software architectures is developed
