The configuration of the virtual host can meet the basic configuration of small and medium-sized websites, and some first-class virtual hosts can even be said to be more than enough. The VPS server provides independent system management permissions and various virtualization environments that virtual hosts cannot provide, but the price is only slightly higher than that of virtual hosts. The Korean VPS introduced in this article is free of filing like other overseas hosts, and the reputation of Korean computer rooms is not bad. The following will introduce the computer rooms and advantages and disadvantages of Korean VPS from multiple aspects.
　　First of all, the speed is fast. Korean VPS is across the sea from mainland China. Users in the north may feel it particularly obvious. There is a saying that the experience of northern users using Korean VPS is similar to the effect of southern users using Hong Kong VPS. According to the evaluation data, the Ping value of Korean VPS servers is basically controlled at tens of milliseconds, and there are very few routing nodes along the way. Basically, they are all directly connected by submarine optical cables, and the bandwidth can currently support more than 100 megabits. Top computer rooms like KT and other BGP multi-line computer rooms are connected to the CN2 return line, which further reduces latency and improves efficiency.
　　Speaking of this, it is necessary to popularize the Korean VPS server resource supply place-the Korean data computer room. KT is the most famous one among them. It was established in 1981 and has been included in the ranks of 5G so far. Its global business covers four main directions: Gigabit lines, Gigabit wireless networks, Gigabit LTE/5G, and Enterprise LTE/5G. The first Gigabit line provides speeds of more than 1Gbps through existing copper and coaxial infrastructure. The second Gigabit wireless network currently supports data speeds of up to 4.8 Gbps. The last mentioned LTE is a wireless broadband communication standard for mobile devices and data terminals. The principle is to increase capacity and speed by using different radio interfaces and core network improvements. KT's computer room uses the China-Korea CN2 dedicated line and China Unicom Mobile BGP line. The line is stable and does not drop packets. The access speed of users of the three networks is fast. When the host is attacked, it can play a role in cleaning traffic through high bandwidth. It is suitable for users in northern South Korea.  
　　The second one to be mentioned is the LG computer room. This computer room provides various redundant infrastructures, including the required power levels ranging from 2-3kW to 10kW. There are four IDC branches in Korea and abroad. This data center also innovatively provides cloud services for hybrid cloud infrastructure for the first time, with significantly improved flexibility, free line configuration, and high-level security. In addition, the data center also provides cloud migration services. The LG data center is connected to the CN2 dedicated line and China Unicom Mobile BGP line, and the telecom line has been optimized for users in southern South Korea.
　　SK data center is the third well-known Korean VPS data center to be introduced in this article. The data center is committed to AI innovation and is currently mainly exposed to 5G mobile edge computing. However, the data center currently uses international lines, and the latency is higher than the above two data centers.
　　A brief discussion of the data center and main advantages and disadvantages of Korean VPS servers
　　In addition, based on the fact that Korean data centers generally have 400GB cluster hardware firewalls, which most domestic data centers do not have, the security of Korean VPS servers is still quite guaranteed. However, even so, we cannot deny some defects of Korean VPS.
　　First of all, let's talk about the language problem. At present, many first-class American hosting companies support pure Chinese interfaces, while Korean VPS does not currently have this benefit for international users. Moreover, domestic exports are restricted, so the stability and speed performance may not reach the expected level. Of course, based on bandwidth technology, it is obviously not comparable to the United States, the source of the Internet. The price of Korean VPS is not advantageous, and it does not support Paypal or credit card payments like most American hosting companies.
　　The loading speed of Korean VPS is considerable, and the computer room is more than the backbone line connection, but it is slightly inferior to the more mainstream American VPS.
