How to differentiate between single-thread virtual host and dual-line host

Many owners in the purchase of http://www.aliyun.com/zixun/aggregation/14840.html "> virtual host will have such a problem, single virtual host and dual-line virtual host to use what kind of virtual space is good. Virtual host providers often introduce you to their virtual host products, will tend to let you buy a relatively expensive dual-line host, the reason is not only high hardware configuration, access speed and optimize the site space these points. Then a single line virtual host is really useless, not to buy dual-line host it? The answer is no.

Let's take a look at the definition of single and dual-line hosts, the so-called dual-line host that has two different lines of the host, the most common is the same time with the telecommunications and unicom two lines of the host, the dual-line host is a good solution to the telecommunications and netcom can not be very good to achieve interconnection of this problem A single host is a virtual host with a line, the most common is only the host of the telecommunication line or the Unicom line, the access speed will be slower when the telecommunication and Unicom interconnect. The emergence of single and dual-line mainframe is due to the Chinese telecom operators divided into telecommunications companies and netcom companies, because the two companies in a competitive state, so the telecommunications user access to the Netcom server is very slow, netcom users access to the telecommunications server is also very difficult. In order to change the difficult situation of the two kinds of line visits, the virtual host provider cleverly put the original single line server on the basis of another one or more lines, so the dual-line mainframe emerged. Telecom host and Unicom host only in China, overseas virtual host is not a line problem.

As a result of a dual-line host added a line, which for the virtual host service providers, both increase the cost of operating servers, but also improve the maintenance of the server's technical requirements, these factors directly resulting in a dual-line host in the price is generally twice times the single machine. In order to reduce operating costs, the virtual host provider will first recommend a dual-line virtual host to create a quantitative effect. and dual-line host in the site optimization does have a unique advantage, first, the dual-line host has two kinds of lines, in the speed of the site can really take care of different lines of the site visitors, improve the site to the user's friendly experience, second, the dual-line host stability is high, search engine in the crawl Site page will also be easier, The site ranking effect is outstanding.

So does this mean that a single virtual host should be eliminated from the tide of history? In fact, is not the case, single-line host has two-wire host does not have the advantage. Single-line host relative to the two-wire host price advantage prominent, in the initial stage of the site, the website indicators are relatively low, the site is basically in the testing phase, as a replacement for dual-line host in the test operation costs, the purchase of one-way mainframe is a good choice, When the site into the formal operation phase and then decisively replace the dual-line host will not cause any negative impact on the site, and many virtual hosts support single line to double lines. In the operating cost considerations, as a regional nature of the portal, classified information and community Web site is not necessary to purchase a dual-line host construction site, local Web site general Site line centralized, the north generally use Unicom line, the south use of telecommunications lines, in the construction of regional sites when the same line of the same single line virtual host. Using a multiple-line virtual host can only waste line resources and increase the difficulty of the site's operations.
