VPN introduction and application

The Ministry of Industry and Information Technology strictly controls the VPN market, which has affected the daily operations of many foreign trade companies and multinational companies. For the foreign trade industry, VPN is important. The familiar VPNs are GreenVPN, the old "blue light", the sky line, the white pigeon, the swordfish, the game accelerator, etc. Which VPNs are better used? Xiaobian interviewed some colleagues on different VPN experiences.

VPN introduction and application

First interviewed colleagues from the ueeshop technical department. Technical colleagues need to remotely connect to overseas servers during development and maintenance. Most of them use Green VPN. Because of their stability and unlimited time, they support windows, ios and Android terminals. GreenVPN is not stable during use, but the technical supervisor feels that the package is a bit expensive, although there are no restrictions on the line, but there are traffic restrictions. Xiaobian has been used for a while, and I feel that GreenVPN's highlight is that an account supports multiple terminals, downloading software can be used, the software interface is simple, and multiple national lines are available for selection.

The customer service department colleagues also need to use the VPN every day. When answering customer inquiries, they often need to go over the wall to check the customer's website, check the website ranking, check Google traffic analysis and so on. They have been using Lantern (blue light) this old accelerator. Lantern is a wall-over software developed by a foreign non-profit organization. The focus is on the wall-over artifacts that are currently available, free and stable. Personal use is very recommended, easy to operate, open the software can directly over the wall. Of course, Lantern also has an upgraded version of the fee (216 yuan / year), the paid version supports Windows, Android, Mac and Ubuntu, no ads fast and unlimited traffic.

But because of the high frequency of VPN usage, Lantern can't keep up with their job requirements. Since July of this year, the customer service department has begun to switch to the coffee router. The coffee router is a routing device. Just like setting up a network router, you can assign IP to each terminal. You don't need to switch lines. The video and download speed are the same as usual. The most important thing is to plug in the Internet cable to access the external network. With any client and settings, the phone can turn over the wall when it is turned on.

In addition, Xiaobian also interviewed one of our Ueeshop partners, whose business department communicates with foreign customers in real time every day. Before they were their own download VPN, the speed was slow and the network was unstable. Later, the coffee router was used uniformly, which was fast and efficient, and also met the needs of multi-user terminals.

In general, others buy and use existing VPN services, but for our Ueeshop technology CTO Cai Ge, it is easy to build one by yourself. How is the VPN built? First of all, you need to buy an overseas server, and then buy traffic and bandwidth according to actual needs, then build a VPN working environment and install the required software on the server, and finally set up the network agent to complete the wall.

In the interview, Cai Ge mentioned that it is safe to build a server, and can control the traffic and specify the network line. However, the cost of setting up a server is high, the number of connections and traffic require better bandwidth to support, and the development technology is not for everyone. In general, the server that builds the designated line is more suitable for cross-border companies with fixed overseas business transactions. If it is used normally, it is more cost-effective to purchase a VPN.

As for other brands of VPN polymorphism, Tianxing, Sailfish, Xiaobian used several times, the feeling is not much difference, but the connection method is not the same. Polymorphic price is affordable and stable, the browser loading time is about 3 or 4 seconds; Tianxing will give 1 hour free time every day, the switching line is slower; the swordfish is used less, after several times It was KO. There are also some programmers who use VPN Gate. This is an academic experimental VPN. It is not popular on the market. It can replace the VPN of computer IP and temporarily solve the problem that FTP and IP are blocked in the connection server.
