Recently, the major U.S. space companies have played a banner of price reduction, many friends also calculated to buy their own suitable for the United States space, Funkey himself at the same time using to Dad and DH these two U.S. space, combined with some of their experience, Referring to an article on the WordPress.org.cn Yculer, and made some changes to be more suitable for beginners to read, wrote this "Buy American space common misunderstanding", hope to buy American space friends a little help, can understand a little bit of American space behind some knowledge.

1. Anti-search IP can know the number of sites on the server to determine the server load

IDC in the foreign market, the server, IP address and the site is not a one-to-one relationship between a server can have dozens of IP addresses, a site may have several IP addresses, and for security reasons, IDC will be in a server dynamic allocation of many IP addresses, Therefore, the IP address of the reverse query on the same IP other sites, and can not describe the server load. In addition, the current provision of IP reverse query site, technology is not rigorous, accurate rate is low.

2. Is infinite space really "infinite"?

The answer, of course, is no, unlimited space only in the capacity, flow, the number of stations unlimited, in other areas, such as CPU resources, total file number, Apache threads the longest running time, the number of e-mail per hour and so on many aspects are limited, these in the official TOS are clearly marked out, But the place is very humble. Once your site exceeds the standard, Hostgator will normally stop you for a few minutes of the site running time, and DreamHost have the danger of direct closure, this is the most deadly. Therefore, infinite space is the least worth buying a class of space, of course, if it is novice, play is possible.

Barrel principle we all know how much a bucket of water depends on the shortest piece of barrel wall. Space, flow is like a high block of wood on the barrel wall, the obscure use limit written in TOS is the lower block on the barrel wall. The efficiency of your site depends precisely on this.

3.OverSell (over Sale) equals overload (Overload)?

Friends who bought American space should be familiar with these two words.

What is Oversell (over sale) and overload (overload)

With the above infinite space for example, who knows, where there is no infinite space, hard disk is also a big head is not? Infinity is a gimmick, this has nothing to do with oversell, for example, we have a 500GB hard disk space server, the sale of unlimited space, and each account to do resource constraints, such as CPU, the number of files, such as, but this limit is very vague, you say you upload 50,000 php file is 50,000 files, you upload 50,000 MP3 is also 50,000 files, so that the basis for the limitations of IDC is its own experience, which is very difficult to ensure the accuracy rate, For example, this 500GB hard drive estimates 50 sites, CPU limit of 7%, the maximum of not more than 20% per hour, well, to 50 webmaster, this 50 webmaster are very regular maintenance of their own web site, the server runs very easily, IDC found a large part of the space and resources no one to use, tidy up, and then sell , but then came a guy, bought a space to do the movie forum, and uploaded a lot of high-definition movies to do download server (unlimited space and traffic well), the day IP3000, this is finished, although the resources for each account has been limited but the entire server running efficiency down. Once the number and resources exceed the estimate of the service provider, the server is no longer able to support the existing sites to run efficiently, which is called overload (overload).

The current IDC for Reseller (agent) Oversell (over sale) attitude is divided into three kinds, one, allow Oversell (over sale), two, add money to allow Oversell (over sale), three, do not allow Oversell (sales). JS Well, always hope that their interests the biggest words, so at present, whether the business or agents will be oversell (over sale), which is why just buy the space start speed is also OK, then the reason for the slow speed, in fact, Oversell (sales) not necessarily on the overload (overload), If you encounter JS a little conscience, can strictly control the number of sites and resource allocation, this is the best. Once you come across a "reseller", that's a stupid thing to do.

Therefore, Oversell (Super Sale) is a common phenomenon, oversell (over sale) is not equal to overload (overload), can strictly control the number of JS is good. Some people say that I buy the host that does not allow Oversell (sale) not to knot, generally do not allow Oversell (sales) of the space prices are very high, fast to catch the VPS, but do not forget your space in addition to capacity and flow of resources such as the CPU limit, in the purchase does not allow Oversell (over sale) Host you have to look at the space in other aspects of the load to consider synthetically.

4. The space merchant's website quickly explained its host fast?

Currently the United States has a basic implementation of distributed storage, our site's servers will not only exist in the space of the location of the server, the United States data Center is very much, we are more familiar with Dallas, Seattle and so on, very much, not necessarily every data center for Asian customers have good support, And the U.S. space business site is after all for the U.S. users, they will pick their own data center to store their own sites, and in each data center hosting their own servers to deal with global customers, so, the space business's Web site fast Its server is a mistake, take GoDaddy examples, It basically adjusts the Web site in the server every month to achieve load balancing (and, of course, other hosts do the work).

Forget to mention, but also the most important, do not put audio and video files in the United States space!
