Implementing Extranets: The Internet as a Virtual Private Network

The two primary objectives of this chapter are to summarize the material previously discussed in this book and to provide you with a matrix which can help you decide whether or not to implement an extranet. The decision matrix in this chapter is not exhaustive so you need to expand it and tailor it to meet your own needs and unique circumstances. However, it does highlight the challenges and solutions that you should consider in your decision making.
The decision matrix and this chapter cover:
Why people are excited about extranets
Return on Investment Analysis
Extranet access
Extranet availability and reliability
Extranet scalability
Extranet security
Extranet performance
Ease of management
Ease of administration
Maintainability
Future extranet challenges
An example of a large successful extranet operation
A description of what makes extranets successful
This chapter ends with some brief lists and outlines for those readers who have decided to develop and implement an extranet. Thus, there is a list of extranet design principles, an extranet implementation plan outline, and an extranet support plan outline.
I hope that this information, as well as information from other sources in addition to this book, helps you make wise decisions about developing and implementing extranets.
Here is a decision matrix to get you started in thinking about an extranet project.
