Thus far this technique is still inside the company. Indeed, it is too difficult to ensure security for Internet deployment. Therefore, GRID computing is primarily used inside companies or, when necessary, between several companies by using VPN. , & Violante, F. (2002).

It gives the best ROSI - return on security investment). However the security can be improved as shown for RADIUS server. Additionally, some elements may be outsourced as requested by A company, like firewall management, router management, SSL gateway. Company B. Case Study for Medium Protection Internal users are better protected from the Internet attacks than in the first type of architecture with the extra firewall introduction. With the addition of the firewall (as depicted in Figure 4), sensitive servers like Intranet/Extranet Web, Simulation server, e-mail server, and LDAP/RADIUS server, three DMZ are defined on the firewall: • • • One is the Intranet DMZ for hosting Intranet resources like the Intranet Web, the Simulation server, and the e-mail server.

The idea was to gather within a metacomputer a group of small independent units equipped with calculation and storage capacities. But network performance did not make it possible to develop such platforms on WAN. Tools were then developed to allow the installation of clusters on high performance LAN. Parallel virtual machine (PVM) (Sunderam, 1990) was developed by Oak Ridge National Laboratory in 1990, then MPI (Message Passing Interface 1993) (Franke, 1994). These software tools simply made it possible to facilitate the programming of these applications by exchanging messages.
