A Software Architecture for Automatic Deployment of CORBA Components Using Grid Technologies

摘要

Software components turn out to be a convenient model to build complexapplications for scientific computing and to run them on a computational grid.However, deploying complex, component-based applications in a grid environmentis particularly arduous. To prevent the user from directly dealing with a largenumber of execution hosts and their heterogeneity within a grid, theapplication deployment phase must be as automatic as possible. This paperdescribes an architecture for automatic deployment of component-basedapplications on computational grids. In the context of the CORBA ComponentModel (CCM), this paper details all the steps to achieve an automaticdeployment of components as well as the entities involved: a grid accessmiddleware and its grid information service (like OGSI), a component deploymentmodel, as specified by CCM, an enriched application description and adeployment planner in order to select resources and map components ontocomputers.
