What is the virtual host, I believe that everyone should understand the site. is in the network server for users to place the site and application of the main part of the network space, with the site data storage and transmission functions. Now, most of our personal web site is to choose to hire a virtual host, so that the virtual host rental has also become the development of the Internet in a new form, because of this, the current network host rental vendors are a mixed bag, not very standard. So, how do we choose the virtual host when we do the Web site? Below, we will be interested in a detailed description of the friends of this method, I hope to be helpful.

The role of the network host if we all understand, we will be clear, since he has to have the network data storage and transmission functions, then we know, we have to consider from a few aspects. The bandwidth line of the virtual host, script support selection, traffic and concurrent selection, this is the three main indicators of the function of the virtual host. In addition, since we have to choose to rent this service, then we must have a certain understanding of the rental service providers, whether there is a good reputation, whether there is a good after-sales service and so on. If we are in a reputable company, selected for their own site to use the bandwidth line, script support selection, traffic and concurrent selection of the relevant indicators of the virtual host, then, we will be in the later use of the process must be relatively smooth.

At present, there are many kinds of bandwidth selection of network, which is familiar to all, including telecommunications, Unicom, Netcom, mobile, education Network and Railcom, and so on, there are many small suppliers who are not very familiar with it. As we all know, the general line of the Web site access speed will be faster, and different line access may have a variety of problems. A user who uses the Netcom line to access a same for netcom line space, then his speed will be very fast, if the user uses the line of telecommunications, so long may appear to open the network speed slow or even open the situation. In China's network situation, the general North Netcom users more, while the southern users are more focused on telecommunications users. So, before we choose a virtual host, we need to know more about what area our customers belong to. If we were in the south, our main customers are also from the south, then the telecommunications line is our better choice; If, we are in the north, our main users from the north, then we should choose Netcom users, to maintain consistency, will make our users visit our site is a good user experience. If our users are from all over the country, north of the South have, Netcom, telecommunications and even other railcom, mobile, Unicom network line users have, then how do we choose? Then you have to choose between a two-line line or a BGP line, as to what is a two-line line, what is a BGP line, I want to do the network of these basic knowledge should still have.

After choosing the bandwidth line that is suitable for your website, we should consider the script support selection of the virtual host. Commonly used Web site programs are mainly, HTML, ASP, asp.net, PHP, JSP, several, according to their own network procedures required by the environment to choose what script support mode we should use. For vendors, there are not many support JSP, generally for the first four kinds of support. In addition, for scripting support options, there are now two types of vendors, one four supported at the same time, and the other one that is separate from ASP and asp.net. As for that kind of better, in fact, this is not a fixed statement. Generally speaking, a variety of scripts are better to separate, because this can be better for server security protection. Said so much, or according to their own web site procedures to choose the right bar.

In addition, the virtual host of traffic and concurrent selection is another important factor we must focus on. Flow is what I believe here does not need to explain, generally is a monthly calculation of several G. This is the type of site, if only a general personal site, then maybe 10G traffic is enough, if you do is a public website, then the likely flow of demand will be greater. Concurrent selection means that several simultaneous requests to the server can be supported. For example, if your virtual host's concurrent selection is 10, then on behalf of the virtual host can meet 10 users at the same time to the server to bring access requests, if, 12 people at the same time, it may be someone can not open. If this simultaneous request for access is an accidental event, so to no matter, can not open the user will be able to refresh again, if it is a long-term use of concurrency, maybe the site will have problems, means that there are always some customers can not open our website, it can be our virtual host selection is not reasonable. Therefore, regarding the virtual host traffic and the concurrent choice, we need to estimate and confirm our website target access quantity first, as well as according to our website content to estimate our website to need the virtual host traffic and the concurrency. There is also a point to remind everyone is that these indicators are limited, if there is a supplier to you that can provide unlimited traffic, unlimited concurrent virtual host, then you may want to pay attention, because this is very abnormal. Or the supplier is lying to you, in the future use of the process will appear some other restrictions, or means that a dangerous existence, many people share a server, if everyone is not limited, once the number of Web site traffic is not controllable, resulting in all virtual space users will collapse.

We have previously defined how we are going to choose our virtual host based on three metrics. If we have a certain understanding of our site, then we choose the virtual host will not be fundamentally problematic. If we choose a more responsible service provider, there is a good sense of services, even if there are some problems in the process of reuse, can be resolved quickly. Therefore, we choose the virtual Host service provider, whether it is based on the evaluation of the industry, or query the supplier in the industry, or the status of major projects, or according to the Ministry of Public record or not to test, must choose some good reputation, in the industry has a certain reputation, Able to provide some of the more timely service of the virtual host provider. Because no matter how cautious we choose, in the use of the process will inevitably appear some problems, must not because of costs and other considerations and use some informal suppliers, otherwise, once the problem, may cause irreparable damage.
