Large Data processing companies like IBM, Sun, Microsoft, Platform, and United Devices have taken a clear turn in the direction of the GRID. html) is a software architecture designed to pool together large amounts of low cost modular storage and servers to create a virtual computing resource which can be transparently distributed. The resources can include storage, servers, database servers, application servers, and applications. Pooling resources together offers dependable, consistent, pervasive, and inexpensive access to these resources regardless of their location and the period where they are needed.

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). A reputationbased approach for choosing reliable resources in peer-to-peer networks. Ninth ACM Conference on Computer and Communications Security. , Nicod, J. , & Philippe, L. (2004). A data persistency approach for the DIET metacomputing environment.

They are still located on a DMZ of the “external” firewall because incoming traffic addressed to these two servers comes mainly from external area. The RADIUS server is used both for internal staff authentication, and remote offices/users’ one. Considering the number of employees, it seems that the number of authentication requests seems to be higher from the internal area. Therefore, RADIUS is located on a DMZ of the “internal” firewall. Because there are more DMZs than in the previous architecture, e-mail server can be located in a DMZ of a firewall.
