For small and medium-sized enterprises and personal webmaster, choose a suitable for their own virtual host is critical, because this is related to the future development of the site. The basic condition of evaluating a good virtual host is stable and fast. I'll share some of my experiences with the novice in choosing a virtual host.

I. Basic CONCEPTS

1. What is a virtual host

Virtual host is the use of special hardware and software technology, a running on the Internet server host into a "virtual" host, each virtual host has a separate domain name, with a complete Internet server (WWW, FTP, email, etc.) function, virtual host completely independent, And can be managed by the user, in the outside view, each virtual host and a stand-alone host exactly the same.

2.IIS explanation

IIS connection number refers to the number of concurrent connections, what do you mean?

To be divided into several situations: (Take 100M space 50 people online for example)

A user to download your files, the end of normal disconnect, these connections are calculated in an instant, that is to say that you 50 of people's Web site can be accepted at the same time 50 points to download

B users open your page, even if you stay on the page does not make any request to the server, then the user opened a side of the next 20 minutes will also be counted as an online, that is to say that you 50 people's Web site within 20 minutes to accept different users to open 50 pages

C in the case of the above B users continue to open the other pages of the same site, then the number of online users in accordance with the user's last click (issued a request) after the 20-minute calculation, in this 20 minutes no matter how users click (including new windows open) are still a person online.

D when your page has a frame (Iframe), then each more frame will be more than one times the online! Because this is equivalent to a user requesting more than one page from the server at the same time.

E when the user opens the page and then closes the browser normally, the number of users online will be cleared immediately.

Then learn what the number of forums online is.

Forum online only calculates the number of active users for a certain period of time.

Here the time users can set their own, the Dynamic Network forum defaults to 40 minutes of relatively accurate values.

Users can choose according to the characteristics of the site, such as the author's website is a Web site navigation station, you should choose not to restrict IIS-type, ordinary Web site to choose the number of IIS 100 is enough, almost can support 2000 independent IP days.

3. Single and dual style virtual host

Due to regional reasons, the north is now dominated by Netcom, the South mainly telecommunications, and telecommunications and netcom exchanges between the speed will be very slow. If the Web site nationwide, it is best to choose a dual-line host, so that the telecommunications and Netcom users will not slow, for the regional site, select a single one is enough.

Here's one more thing to explain, why is multiple lines cheaper than dual-line space? Because the current multi-line technology is not very mature, probably every month will appear one or two times the problem, no two-line space stability, so the price of multiple lines will be lower.

Two. Mistaken selection

1. Select a virtual host without any restrictions

Some virtual host providers have introduced unlimited CPU usage, IIS, unlimited flow of the virtual host, and the price is relatively cheap, the first look is relatively good, but careful analysis, it is not the case. Like a car running on the road, if there is no control, the theory is that the car is to run how fast, but without control, will cause traffic congestion. The same truth, the server on the download station, forum station such a large consumption of resources will be the entire server down, the site's access speed can be imagined. According to the characteristics of the site, we can choose the limit of traffic or limit the number of IIS space.

2. The greater the choice of space, the better

The larger the space, the more you spend, causing unnecessary waste. A basic page of about 150K, a medium-sized site 1000 pages is 150M, plus some other things 300M size space is enough. Some service providers to provide 1G as long as more than 100 yuan space, we just calculate to know, a general server's hard disk size is 73G, service providers will be sold out of the whole, a year can only sell 7300 yuan, not including the wages of employees. and a better server price is about 60,000 yuan. The quality of such a space do not need me to say you should know.

Three. Recommends

1. Do not put together with the drop station or forum station. Because this kind of web site consumes a large bandwidth, it will affect the speed of access to the site. We just look at the space of the introduction is allowed to put this kind of site, did not say generally are allowed, such a space is best not to buy.

2. Find agents to buy. Generally speaking, the price of agents will be cheaper, but if there is a virtual host problem, can only be reflected to the agent, in the agent to the original operator reflected. However, we must find out whether the agents we choose are real agents.
