The Anatomy of a Grid portal

In this paper we introduce a new way to deal with Grid portals referring to our implementation L-GRID is a light portal to access the EGEE/EGI Grid infrastructure via Web allowing users to submit their jobs from a common Web browser in a few minutes without any knowledge about the Grid infrastructure It provides the control over the complete lifecycle of a Grid Job from its submission and status monitoring to the output retrieval The system implemented as client-server architecture is based on the Globus Grid middleware The client side application is based on a java applet; the server relies on a Globus User Interface There is no need of user registration on the server side and the user needs only his own X509 personal certificate The system is user-friendly secure (it uses SSL protocol mechanism for dynamic delegation and identity creation in public key infrastructures) highly customizable open source and easy to install The X509 personal certificate does not get out from the local machine It allows to reduce the time spent for the job submission granting at the same time a higher efficiency and a better security level in proxy delegation and management
