Implementing a Web Services Architecture Framework in a Grid Infrastructure
Serena Pastore · 2005
A major paradigm shift in distributed computing technologies has led during recent years towards two most notably solutions that are represented by grid computing principles and web services technologies and are converging versus a common framework. The grid model focus on large-scale heterogene- ous resource sharing in distributed system in a flexible, secure and coordination fashion, while interoperability, integration and ubiquity are essential character- istics of web services architectures. By combining elements from the two para- digms, the paper shows the implementation of a web service framework hosted in a grid infrastructure covering the mapping of web services process actors and grid components. The resulting architectural framework has been tested with a grid application composed by a set of java web services able to access astro- nomical databases. The document also focuses on the service discovery issue that being a key component of the two underlying architectures requires a suit- able solution for both grid and web services environments.
