VPN (Virtual Private Network)

Where are your SAP servers located?

You might have faced this question in interviews. The answer is simple. In general the servers will be located at client side. You may be working for any company like Wipro, IBM, TCS or Infosys.

That IT company may be implementing the SAP for a customer in UK. Though you work from IT company, the servers will be located at client side only.

How do you connect to SAP servers which are at client side, if you are working from offshore? We can connect through Internet or Private lines.

If you use Internet, it is not secure because of its accessibility to public. Private Lines are costly for the companies. Here VPN comes into picture.

As the name itself tells us that it is secure. We will see what exactly it is.

A Virtual private Network is a private communications network used within a company, or by several companies or organizations to communicate confidentially over non-private network.

From the above definition it is clear that VPN also uses non-private network like Internet. But it creates a virtual network

Tell me the example VPN software names?

AT&T and Citrix. There are many VPN softwares in the market.
