Service-Oriented Architecture for NVO and TeraGrid Computing
- Friday, 12 September 2008
The National Virtual Observatory (NVO) Extensible Secure Scalable Service Infrastructure (NESSSI) is a Web service architecture and software framework (see figure) that enables Web-based astronomical data publish - ing and processing on grid computers such as the National Science Foun - dation’s TeraGrid. Charac ter istics of this architecture include the following:
- Services are created, managed, and upgraded by their developers, who are trusted users of computing platforms on which the services are deployed.
- Service jobs can be initiated by means of Java or Python client programs run on a command line or with Web portals.
- Access is granted within a graduated security scheme in which the size of a job that can be initiated depends on the level of authentication of the user.
