This article mainly explains "what problems should be paid attention to in the selection and purchase of overseas VPS hosts". The explanation in the article is simple and clear, and it is easy to learn and understand. Please follow the editor's train of thought to study and learn what problems need to be paid attention to in the selection and purchase of overseas VPS hosts.

What is VPS? What is self-managed VPS?

VPS is a virtual server. I saw a post on the Internet a long time ago, and I thought it was very interesting. Spray is Zhao Rong tribe introduced by a Chinese host business, the original words are like this: xx host garbage, are divided into those servers from abroad to sell. I think this spray is quite funny, popular to say that VPS is divided by the server, is there a problem? For example, if you don't even have basic common sense, it's obviously not suitable to buy VPS.

With regard to self-managed VPS and unmanaged products, Zhao Yirong's personal understanding is that unless the machine is down and the network is down, other problems need to be solved on their own.

Second, do I need overseas VPS, or why do I need overseas VPS?

First of all, give myself a reason for what I buy overseas VPS to do, such as learning Linux, or learning to set up an environment, or even a scientific way to surf the Internet to learn more truth, and so on. Which one do you start from? you should have a basic positioning, which is related to the product location or configuration you need. If you just want to be a small personal station and don't like messing around, I personally think virtual host is a better choice.

Third, do I need American VPS or Hong Kong VPS (or Asian VPS)?

VPS in the United States generally has larger bandwidth and lower price (relativity); Hong Kong VPS has fast access speed in China, but the bandwidth is limited. Therefore, it is very necessary to choose according to your own needs.

4. Do I know enough about the rules and risks of purchasing overseas VPS?

Foreign host companies sell overseas VPS generally support PayPal or credit card (dual currency card) payment, very few also support Alipay, there are a considerable number of foreign host companies audit accounts, manually open mainframe, etc., can you agree and accept these rules? Do you have these payment accounts? Do you accept manual audit opening time for more than 24 hours? These are all things to consider. Those who are accustomed to using false and random information may terminate their accounts at any time, or become fraudulent orders immediately after the direct order is submitted. In addition, although very few people have done a good job in running away, it is not an absolutely impossible situation. Can you bear the risk yourself? As an adult, after buying, regret or tragedy, to scold the person who told you the information, have to make people doubt your intelligence and ability, at least think about it and decide to pay and bear all the possible consequences and responsibilities.

Fifth, should I buy the VPS of the foreign host company or the VPS of the Chinese host company?

I think each has its own advantages. Chinese VPS hosts generally support Alipay to facilitate payment; Chinese VPS hosts generally have Chinese pages, Chinese panels, Chinese work order customer service support, convenient communication. .. However, many friends do not trust Chinese host operators for many reasons, such as running away, or poor service, and so on. I personally think there are many subjective reasons. I believe that the difficulty of expressing the same problem in English and Chinese is different. Chinese IDC must bear more "obligations", so consider this aspect.

Does foreign VPS support refund? How did you return it?

Some friends often leave messages on the blog to ask questions about refunds. I suggest that users read the terms of service of the host before buying VPS. Foreign hosts are generally TOS (Terms of Service), AUP (Acceptable Use Policy) and the like. They generally have links to the TOS page on the home page. Read the refund section carefully and confirm the specific matters according to the terms. The vast majority of refunds need to be submitted by submitting a work order within a limited time, and any request that does not meet the terms of service may be rejected and reasonable. Some terms of service have made it clear that if you buy a refund and return it, you can only say that you are vexatious, so look carefully before you can have fewer disputes.

7. Are VPS's resources exclusive? Such as CPU, memory, hard disk, bandwidth and so on.

This problem is actually very contradictory. These days, memory is worthless, hard drives are not valuable, and hens can match high points. However, CPU does not mean that it can be changed as soon as possible, and the bandwidth is not infinitely increased, so resources can only be regarded as exclusive in theory at best, but more can be regarded as peak value in practice. Anyway, I think so, I will not ask the host business such an awkward question, how to ask people to answer? It's not like sharing, but the truth is that all VPS shares hen resources, and if you have a penchant for cleanliness, you'd better choose an independent server (in fact, I think independent servers are strictly shared, otherwise you ask how much bandwidth is allocated by a cabinet in a computer room and how much bandwidth is there in a computer room).

Why is there only 200KB/s for the 2m bandwidth download of the VPS configuration I bought?

This kind of common sense question is still asked by many friends. In fact, the most convenient thing is to ask your broadband operator, such as China Telecom, the unit of bandwidth is Mbps, and if MB/s is divided by 8, for example, 1m download is 128KB/s. This is still a theoretical value, without taking into account objective factors. Generally, it is normal in 100KB/s. Here we have to talk about the bandwidth of VPS in the United States. For example, most VPS in the United States have 100m bandwidth (peak, shared). Does this mean that my home is also a 100-megabyte telecom optical fiber, so downloading files on VPS will lead to a 10M/s? The answer is no! If you have similar expectations, don't buy any overseas VPS, just buy a domestic one. There is no guarantee that the speed of domestic download in the United States is affected by factors such as Sino-American lines. Yes, you read it correctly, there is really no guarantee (because no one on the line has the ability to guarantee it)!

9. Is there no limit to what VPS can play? Such as porn, adult content.

If you buy VPS from foreign host companies, you should determine what content is allowed according to the terms of service, not all regions can put adult content; if you buy overseas VPS from Chinese host companies, I can tell you that except for prohibited content, all violations of national laws and regulations are not allowed, although the server is allowed by the country, Chinese host companies are also not allowed! You have to ask, why? You are in China, others are in China, you are not afraid to check the water meter, others are afraid! Therefore, to do this, we should not harm our compatriots.

Is VPS freaking out? Is there an overseas VPS that doesn't have a fuss?

This is a joke, at least in my opinion, as I said at the end of each article, "there is no guarantee that all overseas network products will have the same access experience in any part of China, at any time. The pursuit of perfect experience of domestic products is your best choice. The kind of person who claims that there is no trouble in a computer room is either a liar or an idiot." I insist on similar remarks. Therefore, similar questions do not need to ask the host company, directly ask themselves whether they can accept it, the problem of the line can not be solved by any host company, which is an uncontrollable factor.

We have seen negative bad user information for any business, including Hostus VPS hosts, including my hesitation in choosing, but there is some personal suggestion in our selection skills as VPS hosts. We should consider the comments of other users when choosing, but some of the speed of experience still needs to be tried in practice, because sometimes projects that are not suitable for others may not be suitable for us.

If we only use it to build personal blogs, learning and building stations, there is no big problem with cheap VPS hosts, which can basically meet the needs of most of our users. If we want to pay more than ten dollars a year for VPS, how fast can we download and surf the Internet, then where is the market for some very expensive machines? Individuals always think that what suits us is a good product, and we can use the refund cycle to try and decide whether to continue to use or refund.

To sum up, like many cheap VPS hosts, Hostus is only one of many cheap merchants. We can choose to try it once. At least so far, the VPS in the computer rooms of Hong Kong and Los Angeles in the hands of Xiaobian is relatively stable, at least not yet.

11. How many people can access this VPS configuration?

There is no answer to this question, the number of visitors is only part of the factor, and there are many aspects related to PV, page size, environment component parameters, degree of optimization, and so on. Let's answer this question with a passage from emshost's boss:

(1) the resources (CPU, memory, etc.) consumed by a static (HTML, JS, picture, etc.) HTTP request and a dynamic (ASP, PHP, etc.) HTTP request differ by several times to dozens of times.

(2) Note that the above is a HTTP request, not a page visit (1PV), and the number of HTTP requests generated by each visit may vary several times.

(3) the PV generated by an IP may vary several times, and your website may have a fixed proportion of IP and PV visits so that you can calculate the number of PV according to the amount of IP, even if it can be calculated, it doesn't make any sense, as described in summary and summary.

(4) different website programs have different load capacity. Generally speaking, static HTML consumes far less resources than dynamic programs (PHP, ASP, etc.). The resource consumption of different static web pages is roughly the same, and the resource gap consumed by different dynamic website programs is relatively large due to the large base.

(5) the same website program, different settings, different resources consumed. Take Discuz and DedeCMS as an example, the backend of the website is prompted for load-related settings.

(6) different Web servers have different load capacity. Generally speaking, the Web server resource consumption commonly used on Linux is as follows: APACHE > Lighttpd ≈ Nginx.

(7) in the same server environment (Web, DB), the resources consumed may be different with different setting parameters.

* Note: the "same" and "different" mentioned in each of the above articles are based on the assumption that other factors are exactly the same (obviously, this assumption is limited to theory, so it cannot be used in practical calculation at all).

Based on the above reasons, some users want to calculate the relevant resources on the condition of "the same website program" or "a certain number of PV or IP". The answer here can only be, but not.

XII. About project support

Generally speaking, the project requirements for cheap VPS hosts are basically to build stations to reduce costs, to build Internet access tools to meet the needs of individual users, at least cost-effective and stable than purchasing VIP accounts, and for some of our projects that build remote operations. For example, some users who build VNC remote WINDOWS desktops are used to operate Amazon and EBAY brushing projects.

If we use it to build a site for users, if it is a simple personal blog, the Hong Kong VPS of 256MB memory can barely be used. If the traffic is large, it is recommended that the 512MB is above. It is basically not a big problem for the US and other computer rooms to pay US $12 per year (768MB memory scheme). And the Hostus VPS host supports PPP/TUN components, but we need to open it in the panel. However, it is not recommended to use this way to surf the Internet, because the speed and stability are not good, SS can be used to use SS and other methods, and we can also cooperate with net-speeder acceleration tools.

Thank you for your reading. The above is the content of "what problems should be paid attention to in the selection and purchase of overseas VPS hosts". After the study of this article, I believe you have a deeper understanding of what problems need to be paid attention to in the selection and purchase of overseas VPS hosts, and the specific use needs to be verified in practice.
