Virtual Private Server – The High-End Web Server
The network is no longer new to the world of computers. Now you read these words with the permission of the network. If your office has several computers, then it is likely that they are connected to the same network, which allows you to share folders and files and use the same way to access the Internet to communicate with the rest of the world. Such a network is called a local area network (LAN). After organizations began to cover many sites, they began to use wireless networks (WAN). What to do in situations when company offices begin to appear in several countries? Of course, connecting them with wires is no longer cheap. An alternative solution that meets most requirements and is more reliable and secure is private virtual networks.
What is a Private Virtual Network (VPN)?
There are many definitions of a private virtual network that depend on the goals being pursued. The bottom line, which is common and important for each of these definitions, is that you use an existing network (usually a public network, like the Internet), and then create a virtual network on top of it for your own purposes.
Suppose you have a network of computers in your office that you use extensively while at work. And one day you wanted to access your work materials from home, which are located on working network computers. Obviously, your home computer is not part of the office network. You can remotely log into your computer, if such an option is possible, and use it as if you were in the office. With a VPN, you are on the same office network, although your physical location may not match this. In this case, the VPN will be configured to work over the Internet, giving you access to the organization’s internal network. Thus, you can exchange and share data as if you are in the internal network of the organization, although you are not directly connected to it. VPN gives you the opportunity to use public networks (the Internet in this case) to exchange personal data.
How does a VPN work?
There are two main technologies that facilitate the creation of a VPN and allow you to reliably and securely transfer data through public networks. This is encryption and tunneling. As you may already know, encryption is a shuffling of data so that only a certain recipient can see and understand what you sent him, and for others who are lucky enough to see them, it will look like useless gibberish.
Tunneling is responsible for creating a virtual tunnel, as if you were placing the contents of a packet inside another packet, and then sending it over a public network. The encapsulation protocol is chosen so that for other computers and network devices of the public network through which data can pass, it remains incomprehensible. By combining these two technologies, you can transfer your data through public networks without concern for security and reliability.
Benefits of Using a VPN
As it turned out, a VPN can be easily used to connect several sites (for example, branches) to the main corporate network and to gain remote access to internal networks of organizations (or even your home network, for that matter). Moreover, VPN technology is cheaper in most cases than traditional wireless networks. Hong Kong VPN technology is secure and also provides good performance with high reliability.
