Introduction

American Management Systems is an international consulting, system design and development firm specializing in working with large scale strategic business applications. With the advent of significant commercial use of the Internet, many of our clients, prospects, vendors, and potential employees have access to the Internet. Our client base includes the largest commercial organizations in the financial, telecommunications, insurance, and pharmaceutical industries, as well as large governmental organizations and educational institutions. Many of these organizations have started to use the Internet for electronic mail and several are involved in discussions of broader electronic commerce. Since most of our vendors are themselves in the computer industry, they are also active in using the Internet. Similarly, many of our potential employees are college students who are issued Internet access from the beginning of their studies! While AMS has had direct Internet access for more than a year (domain name “amsinc.com”), we had primarily been using its mail facilities.

To provide better service and to open new opportunities for collaboration, we made the decision to develop a World-Wide-Web server. The advent of Mosaic as a “user friendly” tool for accessing the Internet has changed the perception of Internet use (and users) literally overnight. We saw this as an opportunity to establish a new way of providing access to our services - and of accessing our public.

This presentation discusses the approach that we took and the various issues that our organization had to deal with in creating a Web server for a commercial organization.

Description of the AMS World-Wide-Web Service

The services that we initially sought to provide on the AMS World-Wide-Web (WWW) Server included:

In other words, our intent was to provide a “full service” operation for all of the organizations and people with whom we interact.

Release 1 of the AMS WWW Server is currently available internally to AMS users over our world-wide network (AMSWAN). Internal users use TCP/IP to access our WWW Server running on a 486-based personal computer under the Windows NT operating system.

AMSWAN has been connected to the Internet using UUNET as our service provider for over a year. Anyone on AMSWAN with TCP/IP access has access to most Internet capabilities. On October 31, we will make the AMS WWW server publicly accessible over the Internet by accessing http://www.amsinc.com.

Implementation Issues

After an initial prototyping effort in the spring, development of the AMS WWW Server proceeded over about a three month period. During that time, we dealt with a variety of technical and management issues. However, even the technical issues sprang from management concerns. Once these were dealt with, the actual implementation was fairly straightforward.

Two key types of concerns were expressed in meetings of our internal Internet Task Force:

The first issue could be dealt with by appropriate technical architecture of our Internet gateway, but the second would require an on-going effort as well as the establishment of new policies. Both the design of the technical architecture and the discussion of policy were carried out primarily on-line via Lotus Notes with the sponsorship of AMS's Center for Advanced Technologies.

Technical Architecture

The technical architecture team considered several approaches to ensuring that outside users had acceptable access to our server while other aspects of our internal network were protected. After several design sessions and consultation with technicians at UUNET, we designed a two-tier firewall system using a single leased line into UUNET. This would allow us to have both a WWW server and an FTP server, which we intended to use primarily for updating the contents of the WWW server.

The two-tiered firewall system is built using two Ethernet segments and one IP router. The IP router is used to link AMS to UUNET providing minimal packet filtering on an unsecure Ethernet segment and full packet filtering on the secure segment. The combined WWW/FTP server resides on the "unsecure" network. The secure segment is configured with appropriate IP packet filtering to prevent inbound Internet requests from passing onto the secure Ethernet which could then compromise AMS's wide-area network.

Management Issues

Most of the discussions in designing our Web server were focused on a broad range of management issues. It is impossible to bring up a new corporate communications mechanism like a Web server without surfacing many of these issues. While we did not "solve" them all, we found approaches that provided AMS with an acceptable degree of protection without unduly hampering our ability to create a complete Web server.

Our Ad Hoc Internet Task Force has become an on-going group. We discuss issues. We review policies. We come up with new ideas for additional Web services. We were able to deal with each of these issues at least to some degree and have been able to establish AMS on the World-Wide-Web

Conclusion

Having the opportunity to create a new business medium for your company does not happen very often. The Internet, the World-Wide-Web, and particularly Mosaic, have provided an opportunity that has enormous potential for changing the way in which many business interactions occur. Our ability to set up a World-Wide-Web server for AMS in a relatively short time is just one indication of why thousands of organizations are flocking to the Web as a potential marketplace. We plan to continue the evolution of our server, both with new materials and with new services. We fully expect that all of our customers, vendors, business partners, employees, and recruits will find something of interest and importance on AMS's server on the Web.
