  Nowadays one of the main obstacles the research comes up against is the
difficulty in accessing the required computational resources. Grid is able to
offer the user a wide set of resources, even if they are often too hard to
exploit for non expert end user. Use simplification has today become a common
practice in the access and utilization of Cloud, Grid, and data center
resources. With the launch of L-GRID gateway, we introduced a new way to deal
with Grid portals. L-GRID is an extremely light portal developed in order to
access the EGI Grid infrastructure via Web, allowing users to submit their jobs
from whatever Web browser in a few minutes, without any knowledge about the
underlying Grid infrastructure.
