I have been doing Enterprise Informatization for five years. I have never written any summary. I think I should summarize my technologies and give some suggestions to enterprises that need enterprise informatization.
Case Description
Provide technical consultation to an enterprise. The enterprise is a chain enterprise. It uses a CS-type management system and a local telecom man VPN. Later, the enterprise developed chain stores in other places, metropolitan networks in different cities are expensive, and enterprises require real-time data transmission. (A chain enterprise does not need real-time data transmission, there is no big difference between the sales and real-time in regular transmission, but the cost is very high.) The so-called VPN device on the market usually costs more than 20 thousand, what else does the client charge fees? There is no more than RMB for a dozen stores, and it is really making money for people who don't know how to do it. A word, black.
The problem is how to find the best way to achieve the most economic results. win2003 + isa2006 is undoubtedly the best solution, with VPN and firewall. The cost of such a combination is very small, and the benefits of being born in China are shown here.
