Today, the editor will share with you what are the relevant knowledge points of the basic knowledge points of the virtual host, the content is detailed and the logic is clear. I believe most people still know too much about this knowledge, so share this article for your reference. I hope you can get something after reading this article, let's take a look at it.

What is a virtual host?

Virtual host is to divide a certain disk space on the network server for users to place sites, application components, etc., to provide the necessary site functions and data storage and transmission functions.

The emergence of virtual hosting technology is a great contribution to Internet technology and a gospel for the majority of Internet users. As multiple virtual hosts share the resources of a real host, the hardware costs, network maintenance costs and communication line costs borne by each user are greatly reduced, and Internet has really become an affordable network for everyone! Now, almost all American companies (including some households) have set up their own WEB servers on the network, and a considerable number of them use virtual hosts!

The so-called virtual host, also known as "website space", is to divide a server running on the Internet into multiple "virtual" servers, each of which has an independent domain name and a complete Internet server (supporting WWW, FTP, E-mail, etc.). Different virtual hosts on a server are independent and managed by the user. However, a server host can only support a certain number of virtual hosts, and when this number is exceeded, users will feel a sharp decline in performance.

Virtual hosting technology is a technology adopted by Internet servers to save the cost of server hardware. Virtual hosting technology is mainly applied to HTTP services. One or all of the service contents of a server are logically divided into multiple service units, which are represented as multiple servers, thus making full use of server hardware resources. If the partition is system-level, it is called a virtual server.

Why to establish a virtual host

Internet is increasingly becoming the focus of business attention. Today, with the rapid development of technology, the informatization of enterprises has become an important part of market competition. One of the necessary conditions to go to the market, to internationalize or to keep the domestic market from shrinking is to have a smooth means of modern international contact: their own domain name, their own home page, their own e-mail, their own propaganda position. No matter where your business is and what the conditions are now, the rental of server hard disk space and network virtual hosting services make all this a reality!

Network has increasingly become an important way of marketing, but any enterprise to carry out online e-commerce is a very cautious thing, because it invests a lot in manpower and material resources. When enterprises do not have sufficient conditions, it is very necessary to first establish a virtual host on the network to carry out e-commerce. Let the professional company to undertake the maintenance and management of the system, so that enterprises can save more manpower and costs to do other business. Set up your own virtual host (website server) and you will have long-term online electronic advertising.

Advantages of virtual hosting

The cost is low, although the online information release has obvious advantages of publicity function, but its low cost is still unimaginable. Although advertisements on radio and television stations are calculated in seconds, they often cost tens of thousands of dollars, and newspaper advertisements are also expensive, beyond the affordability of most units. The cost of online information release is greatly reduced due to saving the printing of newspapers and periodicals and the expensive production costs of radio and television stations, so that the vast majority of units and individuals can afford it. With a wide range of coverage, traditional media, whether television, newspapers, radio or light box posters, can not cross geographical restrictions, but can only have an impact on specific areas. The transaction probability is high, for the traditional media advertising, the audience is mostly passive acceptance, it is not easy to produce results. The form is lively and lively, using computer multimedia technology, online information in the form of pictures, text, sound, images and other forms, the shape, use, use, price, purchase method and other information of the products are directly displayed in front of users. With real-time, businesses can change the advertising content at any time according to the needs of the market, flexible and convenient. More importantly, for enterprise and institutional users, this is currently the most economical, convenient and practical way.

There are now nearly 100 million computers connected to ■ Internet. No matter what model they are, what operating system they run, or what software they use, they can be grouped into two main categories: clients and servers.

A client is a machine that accesses other people's information. When you dial up the Internet through the post office or other ISP, your computer is temporarily assigned an IP address. With this temporary ID card, you can get information in the ocean of Internet. When you are disconnected, your computer is disconnected from the Internet,IP address and is withdrawn.

A server is a machine that provides information for others to access, often referred to as a host. Because people can access it at any time, a host must connect to the Internet all the time and have its own permanent IP address. To this end, it is not only necessary to set up dedicated computer hardware, but also to rent expensive data lines, coupled with various maintenance costs such as rent, labor, electricity, and so on, which is by no means easy to bear. For this reason, virtual hosting technology has been developed.

By using the virtual host technology, a real host can be divided into many "virtual" hosts, each of which has an independent domain name and IP address and a complete Internet server function. Virtual hosts are completely independent, and in the outside world, each virtual host is exactly the same as an independent host. The effect is the same, but the cost is very different. As multiple virtual hosts share the resources of a real host, the hardware costs, network maintenance costs and communication line costs borne by each virtual host user are greatly reduced, and Internet has really become an affordable network for everyone!

At present, many enterprises use this method to set up websites, which not only greatly saves the cost of purchasing machines and leasing dedicated lines, but also does not have to worry about the technical problems of using and maintaining the server, let alone hiring specialized managers.

How to choose a virtual host?

1. Can the IP address be accessed?

First of all, if the users of your web hosting site are facing China in the future, the question you must consider is whether the IP address on this virtual host can be accessed smoothly in China, which is due to well-known reasons. If you can't buy a visit, it's troublesome to get a refund. For example, PowWeb is a very good host business abroad, but his IP visit is not complete at home, so you can't buy it. The ten hosts that will be introduced below are all tested or used that can be accessed smoothly in China.

two。 Hardware facilities of the mainframe

The virtual host computer room owned by the virtual hosting provider is a data center of what scale. Whether there is enough bandwidth of the computer room line, and whether the connection speed of the virtual host website can meet the traffic bandwidth of all his virtual host customers at the same time.

Because there are many customers of foreign virtual host vendors, the overall external dedicated line bandwidth of their computer room (data center) must be relatively large to meet the demand. For example, our virtual host manufacturer IPowerWeb's computer room line bandwidth uses the highest technology scale of OC48 and OC192.

3. How many websites are set up on the virtual host?

Usually a virtual host can set up hundreds to thousands of websites. If a virtual host has a large number of websites, it should have more CPU and memory and use server arrays. If you buy virtual hosts from reseller, a web hosting distributor, they set up as many websites as possible on one host in order to achieve the highest profit, and the virtual host server does not prompt, which hinders your site's speed in the virtual host. Therefore, the best way is to find a reputable large web hosting provider, each of which has a limit on the number of websites to host. But this is generally private. Of course, if you have high speed and control requirements for the site, the ultimate solution is to buy your own independent server.

4. Using vps to build a website

The websites on the virtual host will preempt each other's resources. If the budget allows, you can buy the vps host, which is an upgraded version of the virtual host, but it is not a complete server, so it is a moderate consideration. In addition, server sharing is now more popular in China.

Virtual host technology is a technology used by Internet servers to save the cost of server hardware. Virtual host technology is mainly applied to HTTP services, which logically divides one or all of the service contents of a server into multiple service units, which are represented as multiple servers, so as to make full use of the server hardware.

How to correctly select a virtual host server rental hosting service provider?

one。 The length of operating time is an important criterion to evaluate a virtual hosting provider.

two。 Whether the computer room has a reliable, stable, safe and high-speed computer room is another important criterion to measure a successful virtual host provider. In the Internet industry, there is often such a situation: some companies do not have their own computer room, or even have no computer room at all, but they often promise a variety of services to users at a price much lower than the market price. It is conceivable that without adequate hardware support and technical strength, these promises often end up becoming unrealistic castles in the air. So what is certain is that those companies that do not even want to tell customers the location of the computer room must be fraudulent web hosting providers, and the majority of users should be highly vigilant against this situation.

three。 The extremely high performance-to-price ratio and low price lead to the decline of performance and low price to prevent service providers from losing their excellent reputation, excellent quality, sincere service and the right price, all of which are indispensable for a successful web hosting provider.

four。 It is required to give a demonstration address to a large number of customers online.

five。 Generally speaking, larger service providers have far more investment in hardware equipment, network resources, security, human resources, business reputation, and marketing than ordinary service providers, so the price is often higher, but the quality of service is more guaranteed.

six。 It is best for service providers to provide online management functions such as mailbox, FTP, etc.

seven。 It is particularly important to note that at present, many swindlers use home PC as servers and ADSL as access. The stability and speed of this kind of space are quite poor, so don't be greedy for such petty bargains.

eight。 The space capacity of space size virtual host is an important index to assess the performance of virtual host. Usually, we have to assess the capacity of the following spaces at the same time--

1. Web space, also known as web space, is the main space for storing web pages, programs, pictures, and other files.

2. Database space-the database storage space provided by the virtual host that supports the database

3. LOG space-the storage space for website log (LOG) files.
