The DISA (Distributed Internet Server Array) architecture is a nonstop, scalable and redundant system, which is endorsed by Compaq and Microsoft. Compaq itself has invested almost countless engineering hours verifying and testing each component of the DISA system. White papers on deploying this system reside at Compaq's "active answers" web site at http://www.compaq.com/activeanswers. Microsoft's web site also has numerous resources on DISA.

Although Compaq and Microsoft endorse this solution, the DISA architecture is not limited to their products. What makes this system so valuable is that it can be Apache web servers or IIS web servers, Compaq or Sun servers. It can scale as little or as much as needed to fit the individual needs of each information system. If you follow simple building blocks when beginning your Information System, it will be expandable throughout the years as your company grows and expands its technological needs.
