The VPS is virtual private server abbreviation, literal translation is a fictitious dedicated servers. As the name suggests, it is not a real physical server, but it is also different from the shared Hosting (virtual host), users have full control of the VPS, that is, root Access.

VPS Features

1, relatively independent user isolation: Users no longer because of a variety of resources and fighting, each other in a relatively isolated state.

2, the higher security: thanks to the VPS relatively independent user isolation characteristics, its security compared to shared hosting has greatly improved.

3, have the same user experience as the dedicated server: Users can install their favorite operating system on the VPS, such as the various distributions of Linux, as well as Windows Server operating system, and in the use of the operation and experience, with the control of a dedicated Server is no different.

4. Configuration flexibility is the same as dedicated server: When using shared hosting, some components or services cannot be selected or installed by themselves. Everything is based on the service provider's environment. But with VPS you can choose your favorite operating system, install your favorite software. This is what shared hosting can't do.

VPS Purchase

This article, is my purchase VPS some experience, because of this, this article is only opinion. Next we from the following several aspects, look at the purchase of VPS should pay attention to the details.

Computer room Selection

The choice of computer room is extremely important, the location of the room, bandwidth and so on are the important factors that affect the performance of the VPS. In the purchase of VPS, we must first consider, is the choice of domestic computer room or choose a foreign computer room. Let's start with the domestic machine room.

Domestic VPS

From many predecessors to buy a VPS summed up the experience, if you want to do a career in the country, at the same time with a variety of record conditions and comprehensive website operation capacity, the domestic VPS should be the choice. As opposed to foreign VPS, domestic VPS in speed has unparalleled advantages. From the ping value we can see that many of the use of domestic VPS webmaster or Enterprise, their server ping value of about 60MS, on the 100 are very rare. Of course, the choice of domestic VPS must take into account China's special national conditions-north-South pass. More precisely, it should be a question of interoperability between domestic service providers. Remember, once upon a time, the furthest distance in the world is the distance between telecom and Netcom. Therefore, when we choose the domestic VPS, the choice of the room, will be more inclined to use BGP (marginal Gateway Protocol) of the room. Using BGP, can be a good solution to the problem of North-south, so that visitors, whether in the south or the north, whether using telecommunications or netcom, in the speed can be extremely good experience.

If you want to buy a VPS in China, it is recommended that you use Rashost. Other service providers, I can not say that they are not excellent, but I have not tried, and therefore dare not jump to recommend.

Foreign VPS

Sometimes we have to choose foreign VPS, for example, some foreign trade enterprises, their visitors are not limited to domestic, more from abroad, if the VPS on the domestic, will give foreign visitors to bring extremely bad experience. At the same time, in order to ensure domestic and foreign visitors in the speed of a good experience, in the selection of foreign VPS, the location of the engine room is very important, jumped into our most first and most basic consideration factors. At present, in the speed, is very friendly to China foreign computer room has: San Jose (San Jose) Fremont (Ferrimont) "Los Slide-up (Los Angeles)" Las Vegas (Las Vegas) "Dallas (Dallas)" Pennsylvania (Pennsylvania )。

1, San Jose (San Jose) – No price-reliable service provider has been found for the time being. If you know, please contact me.

2, Fremont (Ferrimont)-Linode as the representative, followed by Nerios. These two are I found, the price is more reliable and services more stable service providers.

(3) Los slide-up (Los Angeles) – The main service providers include Vpsyou, Ecvps, Rashost, diahosting, etc., their prices are more friendly than Linode and Nerios, while customer support Chinese also support Alipay. More convenient.

4, Las Vegas (Las Vegas) – The main service providers include Vpsyou, Ecvps, Rashost, diahosting, etc.

5, Dallas (Dallas) – The main service providers include Vpsyou, Ecvps, Rashost, diahosting, etc.

6, Pennsylvania (Pennsylvania) – represented by Burst, speed is the slowest, ping value sometimes up to 400+ms.

The above mentioned service providers may not be the most outstanding and excellent, but all are I used or tested, I recommend them before, but also Google, their word-of-mouth can be counted. If I am in the process of using or testing also found a good service provider, I will continue to add in.

The choice of virtualization technology

There are VPS based on a variety of virtualization technologies, with a more mainstream VPS based on OpenVZ and Xen virtualization technology. I personally think that the difference between the two is that the former is easy to sell, and most of the service providers are oversold, the latter is not easy to sell, and almost no service provider can oversold. Also, the former does not support PPTP based VPNs because it does not support eth0 virtualization, which is supported.

For the VPS based on OpenVZ virtualization technology, the price is cheaper, but the stability is not much, the stability is now found to be more reliable is ecvps.

For a VPS based on Xen virtualization technology, the price is relatively expensive, but because it is not easy to oversold, so the stability is high. At present the best word-of-mouth is Linode, of course, according to my own test, more reliable and vpsyou and rashost.

Personally, if the site is purely, regardless of the provision of PPTP-based VPN services, based on the OpenVZ virtualization Technology VPS, the price will be more pro-people, of course, consider oversold factors. If you want to provide a PPTP based VPN service, a VPS based on Xen virtualization technology is the choice.

Price considerations

On the price side, to tell the truth, there is nothing to talk about, Shina, is the most reliable. However, here we should note that as far as possible choose to support the monthly payment of the VPS (seemingly most support). Pay about 20USD a month, if the memory can be more than 256M, it is more reliable, otherwise it might as well buy dedicated Server.

Consideration of payment methods

For domestic users, support Alipay that is of course the best, if not support Alipay, that support PayPal or Google Checkout is also more reliable. The payment method is considered mainly from the angle of security. The current mainstream of PayPal and Google Checkout, of course, and Alipay, are more secure online payment methods, when paying the best use of these payment channels, rather than directly fill out credit card information-credit card can not be "everywhere". Use PayPal, Google Checkout and Alipay, although also to expose their credit card or debit card information, but these are large enterprises, to protect the user's personal information security is their foothold in this.

Other factors

In fact, there are several factors to consider when choosing a VPS:

Control Panel: We have to configure the VPS management, friendly Control Panel is very important, such as SOLUSVM, HYPERVM, Veportal and Xen-shell. Some service providers do not provide control Panel, resulting in the installation of the system needs to submit services list, which is more unreliable, such as rashost. Some service providers provide self-developed fully functional control Panel, making management very convenient, such as Linode. Some service providers are not autonomous development, but the function is also more comprehensive control panel, such as: Vpsyou, Ecvps, diahosting.

Technical support: VPS in the after-sales service is divided into Consolidator vps and unmanaged VPS, as the name suggests, the former provides a full range of after-sales service, while the latter provides basic after-sales service such as host machine or network fault detection and elimination. At the same time, the former because of a full range of after-sales service protection, so the price is much more expensive than the latter. And the latter, all rely on the webmaster self-reliance. Specifically, is the purchase of Consolidator VPS, you can ask customer service to help you install some programs, such as Wordpress, Joomla and Discuz, suitable for beginners. The unmanaged VPS does not provide a service to install the program, so it is more suitable for people who understand technology or a little technical skills.

Use restrictions: The use of the VPS is not unlimited, it has been the service provider TOS (User agreement) and local laws, in the purchase of a VPS, must take into account the specific use, and the use of the pre-contract to see if the use of restrictions will be violated. In the course of use, if the illegal user agreement or local law, the VPS may be directly closed, and even the data can not be retrieved, so the loss is big. Of course, there are exceptions, such as domestic service providers and some internet companies registered in the Netherlands, they have fewer restrictions on use, and will be more free to use.

Refund strategy: Make good use of the service provider's refund strategy, can effectively protect their rights, about the refund strategy, each service provider will have some differences, these are all we need to understand. The rules and procedures for refunds are generally described in TOS.
