Extranet Cost Savings
One of the key reasons for the popularity of extranet technology is the wide area network cost savings that some enterprises are able to realize from implementing extranet technology. These savings are especially likely to be realizable when extranets cross geographic boundaries or span long distances and the same or compatible Internet Service Providers can be found at both ends of the extranet.
For example, one of the speakers at the Windows NT/Intranet trade show in the late summer of 1997 claimed that by dropping Integrated Services Digital Network connections in favor of extranet connections implemented via Internet Service Providers, he was able to lower wide area networking line costs from $35,000 per month to $10,000 per month for his clients. Indeed, there seems to be something of a price war going on between long hall WAN providers and Internet Service Providers with wide area line costs dropping as low as $7,000 per month according to some of the presenters at the Windows NT/Internet trade show.
Cost savings like these are likely to please any...
