Now the internet is becoming more and more developed, many enterprises and individual operators, through the Internet business accounted for a greater proportion. Therefore, it is particularly important to choose a suitable product when publishing a business-related website.

Publishing your Web site to the Internet usually has a number of options: a virtual host, a hosting server, a leased server, a rental server, a virtual server (VPS, exclusive servers).

Virtual Host: Usually the price is 100-2000 yuan/year. The usual concept is that the size and quality of space determine the price level. High security, and customer technical input requirements are relatively low, usually need not be equipped with professional technical personnel. Overall is the most economical solution for small businesses and personal sites. However, due to a large number of sites concentrated in a server, so the performance is not high, difficult to meet some large and medium-sized applications. Because it is unified management, can not meet the personalized needs of many websites.

Managed server: Usually the price is 3000-8000 yuan/year. Small city general Telecommunications room price in 3000 yuan/year, the big city high quality room usually price in 6000-8000 yuan/year. Room and service quality determine the price level. Users also need to purchase additional servers according to their respective applications, the cheapest PC+1U chassis power supply is about 3000 yuan, the special business Server usually needs more than 10000 yuan, server performance and quality determine the price. Total investment in 6000-20000 yuan/year.

Because the permissions are dispersed to individual users to manage, so the freedom is very high, alone, users can install their own required software programs, enable the services they need. But also because it is alone management, so users need to be equipped with professional technicians to maintain, which is also a small amount of input. Moreover, because the national high quality rooms are concentrated in Beijing, Shanghai and a few large cities, customers need high-quality room, many customers need to server freight to the corresponding computer room, because the hard disk has precision machinery parts, ordinary freight easily caused by hard disk damage, resulting in data loss, high risk.

Leased server: Usually the price is 6000-20000 yuan/year. is essentially equivalent to the cost of acquiring a server + managed server. Overall input is essentially the same as server hosting. Compared with hosting, the main advantage is no transport risk, and hardware and services are provided by the ISP, in the event of a hardware failure, can be quickly resolved.

Virtual Server (VPS, exclusive Server): Virtual server is divided into VPS and exclusive server. VPS usually price in 2000-4000 yuan/year, exclusive server is usually priced at 5000-7000 yuan/year, the latter performance is stronger, meet high requirements, high budget customers.

Virtual server is the use of virtualization technology, the Super server split into multiple virtual exclusive server services. Can be allocated independent public network IP address, independent operating system, independent super space, independent memory, independent CPU resources, independent execution program and independent system configuration. Virtual servers have almost the same degree of freedom to lease managed standalone servers, and there are many unique advantages: for example, high-quality hardware conditions, more standard more perfect system settings (security, environment, etc.), convenient backup, rapid system recovery, rapid server replacement, room rapid migration, environmental protection and energy conservation.

In short, a virtual server is a highly resilient, high-quality, Low-cost server solution.
