Notice virtual host need

We know thatVirtual host is to divide a certain disk space on the network server for users to place sites and application components. Virtual host is the gospel of network development and greatly promotes the application of network technology. and popularity. At the same time, virtual host rental services have also become a new economic form in the Internet era. Renting a virtual host is similar to renting a house. Today I will tell you some things you need to pay attention to when choosing a virtual host space.

Advantages of virtual hosting:

(1) Compared with purchasing a separate server, the cost of website construction is greatly reduced, which provides great convenience for popularizing small and medium-sized websites; the cost is low, although online information is published It has obvious advantages in publicity functions, but its low cost is still unimaginable. Although advertisements on radio and television stations are calculated in seconds, the cost can easily reach tens of thousands; advertisements in newspapers and periodicals are also expensive and beyond the affordability of most individuals. Online information dissemination saves the printing of newspapers and periodicals and the expensive production costs of radio and television stations, and the cost is greatly reduced, making it affordable for most units and individuals. The coverage is wide. Traditional media, whether TV, newspapers, radio or light box posters, cannot transcend geographical restrictions and can only have an impact on specific areas. The probability of closing a deal is high. For traditional media advertisements, the audience mostly passively accepts them, which is not easy to produce results. The form is vivid and lively, using computermultimedia technology, online information in various forms such as pictures, texts, sounds, images, etc., to directly display the shape, purpose, usage, price, purchase method and other information of the product to the user. before. It is real-time and merchants can change the advertising content at any time according to market needs, which is flexible and convenient. More importantly, for corporate and institutional users, this is currently the most cost-effective, convenient and practical way.

(2) Using virtual host technology, a real host can be divided into many "virtual" hosts. Each virtual host has an independent domain name and IP address, and has complete Internet server functions. Virtual hosts are completely independent from each other. From 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. Since multiple virtual hosts share the resources of one real host, the hardware costs, network maintenance costs, and communication line costs borne by each virtual host user are greatly reduced, and the Internet has truly become a network that everyone can afford. At present, many companies use this method to build websites. This not only greatly saves the cost of purchasing machines and renting dedicated lines, but also simplifies the management of the website server. Security measures such as software configuration, anti-virus, and anti-attack are all taken. Provided by professional service providers, it greatly simplifies the complexity of server management; at the same time, there is no need to worry about the technical issues of using and maintaining the server, nor does it need to hire specialized management personnel. (3) The efficiency of website construction is improved. It takes a long time to buy a server and

install the operating system and application software. However, renting a virtual host usually only takes a few minutes to open it. , because now the major service providers have realized the e-commerce of the entire business process. You can choose the virtual host that suits your needs and activate it immediately after paying online.

(4) The emergence of virtual host technology is a major contribution to the development of Internet technology and networks. Since multiple virtual hosts share the resources of a real host, the utilization of servers and communication lines is greatly increased. Allows multiple network IP addresses to be configured on one server without conflict, which means that people can use virtual hosts to build several sites with separate domain names on one server, without having to purchase additional resources to build a site. A separate server and a huge sum of money are spent to apply for a dedicated line as a network information outlet. Nowadays, most domestic and foreign companies use this method of renting server hard disk space (i.e. virtual host) to build websites. The advantage of virtual host is that it not only greatly saves the cost of purchasing servers and renting dedicated lines, but also eliminates the need to use and maintain servers. There are no technical issues to worry about, and there is no need to have dedicated server management personnel.

(5) The low cost and high utilization rate of virtual hosts quickly attracted small and medium-sized enterprises. In order to adapt to the increasingly fierce international business competition environment after my country's entry into the WTO, accelerate the application of online trading platforms with small investment and fast returns, and strengthen the e-commerce, corporate Internet and other informatization construction, virtual host website building has become a way to improve corporate competitiveness. important means.

Disadvantages of virtual hosting:

(1) Some functions are restricted by service providers, such as forum programs that may consume system resources, traffic statistics functions, etc.;

( 2) Website design needs to consider the functional support provided by the service provider, such as database type, operating system, etc.;

(3) The access speed of some virtual host websites is too slow, which may be due to the host provider converting a The host is rented to a large number of websites, or caused by server configuration and other reasons. This situation cannot be solved by the website itself and will have an adverse impact on the normal access of the website;

(4) Some service providers have certain restrictions on website traffic, so that when the website has a large number of visits, it will not be able to be accessed normally.

It can be seen that whether a website uses a virtual host or a dedicated server needs to be comprehensively considered based on the website's situation and expected development.

(5) In order to reduce costs, general virtual hosts do not have independent IP addresses, that is, the IP address cannot directly access the website (because there are multiple websites with the same IP address)

Choose the correct service provider

1. Length of business operation time.

The length of business operation is an important criterion for evaluating a virtual hosting provider.

2. Extremely high cost performance.

Low prices lead to performance degradation. Low prices should prevent service providers from disappearing. Excellent reputation, excellent quality, sincere service, and appropriate prices are all indispensable for a successful virtual hosting provider.

3. Don’t be greedy for cheap.

Virtual host is a server divided into multiple hosts through virtual host technology. Generally speaking, it is normal to place less than 200 corporate websites or less than 30 functional websites on the server and will not affect the server. Speed; if it exceeds this number, no matter how good the server is, it will be difficult to withstand it. As a result, the speed will decrease and failures will occur frequently.

4. Online management function.

It is best for the service provider to provide online management functions such as virtual host control panel and FTP.

5. Use a home PC as a server.

What needs special attention is that many scammers use home PCs as servers and use ADSL for access. The stability and speed of this kind of space are quite poor. Remember not to be greedy for such small advantages.

6. Data security.

Whether the service provider provides firewall equipment to protect user data security and prevent DDOS attacks. Are there any other illegal websites on the server? If there are other illegal websites on the service, it may cause the entire server to stop running.

7. Whether there is perfect after-sales service.

Whether the service provider has complete after-sales service and monitors user data to avoid harmful information being punished by the communications management department and the public security department. For example: China Wanwang, Gugu Internet, etc. These are all regular ISP access providers and virtual host service providers. They have hardware firewalls, monitoring and other equipment, and have the above advantages.

Setting up a virtual host is very simple. Nowadays, many individuals or companies rent a server and then set it up as many virtual hosts. Therefore, a service provider's strict conditions for customers can also indirectly feedback the performance of the virtual host! If you are building a formal website, do not try to save trouble by using some service providers that are not very strict in auditing; because it is very likely that your website and some irregular websites are on the same server. This will seriously affect the security of your website data!

Virtual host selection:

1. The virtual host must be stable, stability is crucial for SEO;

2. The bandwidth must be sufficient so that the web page loads quickly;

3. Have enough IIS;

4. Support common modules, 404 settings, pseudo-static, shtml, program version, backup, compression and decompression, FTP;

5. When buying domestic space now, be sure to ask about registration issues. If the space provider does not allow you to register or is not qualified for registration, then you will buy a space without a registered domain name, which will be a useless purchase. Space;

6. Is the after-sales service strong? Problems will inevitably occur in the space, but when problems arise, can the space provider handle them in time and is there someone available to serve at any time (especially at night)?

7. Purchase space Whether it supports the language you need, PHP, ASP, ASP.NET, etc.;

8. Don’t be greedy for cheap when purchasing space, as the result will be unstable space.

Other special needs are more specific to your own needs, so be sure to ask clearly before purchasing.

Tsinghua Optics AI appears in Nature! Physical neural network, backpropagation is no longer needed Tsinghua Optics AI appears in Nature! Physical neural network, backpropagation is no longer needed Aug 10, 2024 pm 10:15 PM

Using light to train neural networks, Tsinghua University results were recently published in Nature! What should I do if I cannot apply the backpropagation algorithm? They proposed a Fully Forward Mode (FFM) training method that directly performs the training process in the physical optical system, overcoming the limitations of traditional digital computer simulations. To put it simply, it used to be necessary to model the physical system in detail and then simulate these models on a computer to train the network. The FFM method eliminates the modeling process and allows the system to directly use experimental data for learning and optimization. This also means that training no longer needs to check each layer from back to front (backpropagation), but can directly update the parameters of the network from front to back. To use an analogy, like a puzzle, backpropagation
