This article mainly explains "how to choose and buy a VPS host". Interested friends may wish to have a look. The method introduced in this paper is simple, fast and practical. Let's let the editor take you to learn "how to choose and buy VPS hosts".

Now that VPS is rampant, due to budget reasons, excellent high-end products like Linode can't afford to play, so we have to aim at low-end. The low-end VPS market is even more cluttered-as a result of the low technical threshold, as long as you buy a server hosted in the computer room, you can easily sell VPS, so there are really many dazzling VPS manufacturers, including fraudsters who run away for the last few months (of course, some are not intentional-for example, a customer violates copyright or spam and leads to the whole server being shut down by ISP). Therefore, from the beginning, I have laid down the following principles:

1. Try to choose big brands and old brands-although new manufacturers are generally cheap, they may run away more.

two。 Stability comes first, followed by speed and performance, and price again-- for the construction of a station, stability is more important than the ratio of performance to price, and the performance requirements of small sites are not high. 128m of memory is enough.

3. In any case, insist on monthly payment-because VPS is also affected by complex factors such as neighbors on the same server, even established brands may encounter problems, and monthly payment can minimize losses.

In addition, here is a brief introduction to common virtualization technologies:

1.OpenVZ: a classic paravirtualization technology in which all virtual machines share the host kernel (so you can only install Linux), which is very efficient (there is no need to virtualize many underlying devices), but it also brings a lot of problems: unable to customize the kernel or even load modules (thus unable to use PPTP VPN, etc.), poor stability (only one virtual machine causes kernel panic, the whole server is out of order), and easy to oversell.

2.Xen: divided into PV and HVM:PV is also a paravirtualization technology, but the client runs its own kernel (so it can update the kernel or install the module), but has made some changes to add domU support (so it cannot use closed-source systems such as Windows), which is efficient and stable. HVM is a full virtualization technology, which requires hardware virtualization support. It can run any system without migration, but it is inefficient. Both are more difficult to oversell.

3.KVM: a relatively new full virtualization technology that requires hardware virtualization support and is highly efficient. It is common in high-end VPS.

4.HyperV: a virtualization technology developed by Microsoft that is generally used to run Windows.

After a long period of comparison, the target is finally targeted at the following four more famous, cost-effective low-end VPS. Here is a summary of the comments on them online:

1.BurstNet (editor's note: now closed.): commonly known as 84, veteran VPS, the world's top 500, large scale, famous for cheap OpenVZ, the speed is not poor, but it is said that oversold is more serious and stable.

2.YardVPS/PhotonVPS: two brands under the same company run by Taiwanese, the former is low-end Unmanaged VPS, the latter is slightly better Semi-managed VPS, mainly Xen, generally speaking, the mainland visit speed is faster, the most important thing is to support Alipay, but the stability is general, and the customer service of Yard is poor.

3.ThrustVPS (editor's note: also closed...): formerly known as DamnVPS, with a long history and a wide distribution of computer rooms, both OpenVZ and Xen are sold, among which Dallas computer rooms visit mainland China very fast (personal test! However, some time ago, it was acquired by Rus Foster, which has a poor reputation in the VPS world, and there is no shortage of complaints on WHT.

YardVPS

This is the first VPS I used, and it was a decision I made after watching a lot of reviews and discussions. There are several main reasons: first, Xen architecture, not oversold, great flexibility (can also take pptp); second, high performance-price ratio, because I am also a veteran of Linux, unmanaged is more than sufficient; third, the speed of visiting the mainland is fast, and the monthly traffic is large, which is suitable for VPN;. Fourth, support Alipay.

I chose Yard's Tree 1 program for $8 a month. In the first month after payment, the use feels first-class, and the speed is really good. The ping value is less than 200ms, and the packet loss rate is less than 3%. Using OpenVPN in 10m broadband can reach the speed of 4m, which is more than enough for Youtube HD. And excellent performance, set up LNMP and OpenVPN and Squid, but also can maintain the year-round load of 0.00 level (which is actually a waste). RDNS settings need to send Ticket to customer service, customer service response is also very fast, opened on the same day.

In the second month, however, the network began to show some anomalies. At the beginning, the delay of SSH increases and the packet loss rate increases. Subsequently, the packet loss rate is even as high as more than 70%. To make sure it's not a local network problem, I also tested it with just-ping.com, and the results show that packet loss rates are high all over the world. Such a high packet loss rate, whether it's SSH, HTTP or anything else, is basically inaccessible.

At this point, I believe you have a deeper understanding of "how to choose and buy VPS host". You might as well do it in practice. Here is the website, more related content can enter the relevant channels to inquire, follow us, continue to learn!
