Virtual Private Networks and Their Function as Middleware
Several technological advances have made it easier for employees to keep in touch with their company without physically being in the office. ...
The growing popularity of VPN (virtual private network) connections is addressing the drawbacks of previous office connections, while offering greater security and flexibility. ... Through tunneling, the private information is invisible to others on the web. ... In the past, implementing a WAN (wide area network) to link two or more remote networks was a complicated and expensive undertaking. ... “These private networks were not easy to use, cheap, or particularly reliable, but they were a necessity. ... (Apicella) Problematic modems used for dial-up access can be replaced with a virtual connection that only requires an Internet connection. ... As a gateway into a private network, or a way for two private networks to share information, a VPN is an important piece of middleware for several reasons. ...
According to the textbook, there are five primary goals of middleware: “…hardware independence, interchangeability of key software components, network independence, operational savings, and administrative savings. ... The fact that more than one network can connect using the VPN, and yet remain independent networks in their own rights locally, provides the next requirement of network independence. ...
The textbook goes on to say that middleware “…should do several things. ... Once again, the VPN solution meets these requirements, and therefore can be defined as middleware.
From a functional view of middleware, a VPN can be seen to perform both as an information-exchange service, and as a management and support service.
