Six main points for choosing a virtual host service

One of the information work is to open a Web site, but for a large number of small enterprises, the opening of the Web site involves the choice of virtual host. This is a seemingly simple, but actually there are a lot of "stress" of the work.

The use of virtual host technology, you can put a real host into a number of "virtual" host, they are completely independent, in the view of the outside world, each virtual host and a stand-alone host exactly the same. The effect is the same, but the cost is very different, because many users share a real host of resources, each user to bear the hardware costs, network maintenance costs, communication line costs are greatly reduced. So, many businesses, in particular, small-scale enterprises in the establishment of Web sites are used in this way, not only greatly reduce the cost of purchasing machines and leased lines, but also do not have to use and maintain the server's technical problems worry, not to hire a dedicated managers, because these things are handled by the service provider. But in reality, the service providers in order to profit as often as possible to infringe on the interests of users, so users need to be in the selection of careful inspection, which focuses on the following points.

　　First, the amount of load

Load is much more important than space capacity, although the application of the virtual host is a number of users to share a stand-alone server, but users need to understand to the service provider, in the end how many users to share the same server resources. Because only the service providers in the various users of the share of resources to make a fair distribution, can really guarantee the real interests of most users. If you share too many users, server overload operation, it will reduce the stability of the server, reduce CPU processing power, the program is difficult to run, so that users can not find the page when visiting the site, unable to link to the database, or even inaccessible and other serious failures.

Generally speaking, according to the different service categories provided by the virtual host, a server shares a few users, and should not be more than hundreds of user's limit. And some servers are not enough service providers, in order to maximize the use of the hands of limited hardware resources, and even in a server placed thousands of users, the effect can be thought of. Therefore, if we want to obtain the "reasonable resources" to protect the virtual services, we must pay attention to the strength of the service provider. such as the number of servers used by the service provider, the "specific" commitment to the user load in the selected virtual host service. So it's a good idea to choose that large web hosting provider as a partner in multiple comparisons.

　　Second, flow

Traffic is the user site may be the number of visits, service providers are also in the principle of fair allocation of resources to the server, each user site traffic restrictions, but the problem is the extent of their restrictions. If the limit of the value is too small will greatly damage the interests of users, or even think that, if the traffic value is very small, the site's storage space is not useful, because this will make the user site browsing speed is particularly slow.

Generally speaking, as long as the service provider to provide more than sufficient hardware resources will not be too restrictive traffic. And those who try to "fully" use limited hardware facilities, can not provide a lot of traffic service providers, in order to be able to attract as many users as possible, will take only to add a hard drive without adding server this at the expense of server stability at the cost of the method, the same type of virtual host space capacity of dozens of trillion, to advertise its "super big" advantage.

　　Third, the number of links

The number of links refers to the number of users who can accept the application and open the Web page at the same time, the size of the link value is directly related to the access level of the user site on the virtual host. If you limit the number of links to too few, then the number of users can access the site is very limited, the user page will appear to allow the visitor to wait too long, such as the normal situation, the general number of links to support the standard will not be limited to indicators. But some small service providers for the convenience of monitoring users, forcing them to choose a high price level of the virtual service type, but also to the number of links to do a hard numerical division, so users need to pay special attention to purchase.

　　Iv. on-line rate

Since the establishment of the site should always keep it running, to ensure that visitors can log on at any time. This is a logical requirement that foreign virtual hosting providers generally make a commitment to the online rate of their users ' websites. But in the domestic only a few service providers have made a clear commitment to ensure the online rate of users ' websites, most service providers because of bandwidth, hardware equipment and technical management capacity constraints, it is easy to produce downtime problems, so can not or do not want to make public "quantification" of the guarantee.

　　Five, flexible degree

Flexibility is whether the service provider can provide users with economical and convenient service choices. There are two points for users to pay special attention: first, whether they can decide to increase the amount of space for the Web site, the other is whether the same price to use a different operating system platform. Because these two problems are directly related to the interests of the user, once the user's website developed to the original space capacity close to saturation, users must add more configuration to the line. But the question is, many service providers for high profits, generally do not allow users to 10 trillion, 20 trillion to add a small amount of space, but only to allow the increase in the number of megabytes, disguised as forcing users to upgrade, which will allow users to spend a lot of money to buy those who do not use the rich resources.

and the operating system can be free to choose the same, some users are accustomed to using UNIX platform, and some are good at using Windows NT to do Web site platform, but some manufacturers will be based on this use of the difference between the same type of Web site division of the price of different grades. So I want users to "compare" before they buy.

　　Vi. Functions of the website

For many just contact with the network of enterprises and schools, if the service provider provided by the site management interface is not so simple, easy to use, the function is not so complete, the future will be difficult to operate smoothly using the site. Therefore, it should be noted that the service provider for the user's web site, such as the automatic generation of page modules, FrontPage extensions, and so on, so that they can avoid the trouble of doing complex operations.
