The blog has been written for many years, and the part about VPS has also been written for several years. However, based on personal level factors, it has always stayed at a superficial level. Readers are also more beginners. In order to make it easier for novice friends to understand, they have always wanted to sort out some questions that they need to ask themselves and host companies before purchasing overseas VPS. Here is a special page for inclusion, If you have other questions, you can also raise them in the article comments, and I will update them directly in the article. However, please note that these answers are only based on my own superficial understanding and are not authoritative. Readers are only for reference or as a joke.
1、 What is VPS? What is a self managed VPS?
VPS is a virtual server. I saw an article on the Internet a long time ago, and I found it very interesting. The spray is a Chinese host company introduced by Zhao * Rong Tribe. The original saying is: xx host company garbage is divided into foreign servers for sale... I think this spray is very funny. It is generally said that VPS is divided into servers. Is there a problem? For example, if you don't even have basic knowledge, it is obviously not suitable to buy VPS. Let's build a computer room.
As for self managed VPS and unmanaged products, Zhao&Rong's personal understanding is that unless the machine hangs up and the network is down, other problems need to be solved by themselves. Some unmanaged VPS hosts may also reply to and deal with other problems, but please note that this is not an obligation, but a kindness.
2、 Do I need an overseas VPS, or why do I need an overseas VPS?
First of all, give yourself a reason. What do I buy overseas VPS to do? For example, learn Linux, or learn to set up the environment, or even access the Internet in a scientific way to learn more about the truth. All these are reasons. What kind of product do you start with? You should have a basic positioning, which is related to the product location or configuration you need. If you just want to be a personal website and don't like tossing about, I personally think virtual hosting will be a better choice.
3、 Do I need VPS from the US or Hong Kong (or Asia)?
VPS in the United States generally has larger bandwidth and lower price (relativity); Hong Kong VPS has fast access speed in China, but limited bandwidth. 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 vendors selling overseas VPS generally support PayPal or credit card (dual currency card) payment, and very few also support Alipay. A considerable number of foreign host vendors review accounts, manually open hosts, etc. Can you agree with and accept these rules? Do you have these payment accounts? Will you accept the manual review of the opening time after 24 hours? These are the contents to be considered. Those who are accustomed to using false and arbitrary information may be terminated at any time, or the direct order may become a fraudulent order immediately after submission. In addition, although there are very few people who run well, it is not absolutely impossible. Can you take the risk yourself? As an adult, if you regret or suffer a tragedy after buying, and scold the person who told you the information, you have to let others doubt your intelligence and ability. At least you should decide to pay after your own consideration and bear all the consequences and responsibilities that may arise.
5、 Should I buy a VPS from a foreign host company or a VPS from a Chinese host company?
I think each has its own advantages. Chinese VPS hosts generally support Alipay to facilitate payment; Chinese VPS hosts generally use Chinese pages, Chinese panels, and Chinese work order customer service support to facilitate communication However, many friends do not trust Chinese hosting companies, and there are many reasons for this, such as running away or poor service. I personally think there are many subjective reasons. I believe that the difficulty of expressing the same problem in English and Chinese is different. China IDC is willing to bear more "obligations", so I also consider this aspect myself.
6、 Does foreign VPS support refunds? How did you return it?
Some friends often leave messages on their blogs asking questions about refunds. I suggest users read the terms of service of the hosting company before purchasing VPS. Foreign hosting companies generally include TOS (Terms of Service), AUP (Acceptable Use Policy), etc. They usually have a link to the TOS page on their home page. Read the refund section carefully and confirm specific matters according to the terms, The vast majority of refunds need to be made within a limited time by submitting a work order application. The refund period starts from the date of purchase, not from the date of renewal. Any request that does not comply with the service terms may be rejected and reasonable. PP disputes are not a way of refund. Some service terms have clearly stated that if there is no refund, you can only say that you make trouble for nothing if you want to return after buying, So you can see clearly first and then act with less disputes.
7、 Are VPS resources exclusive? For example, CPU, memory, hard disk, bandwidth, etc.
In fact, this problem is very contradictory. In recent years, memory is not worth money, and hard disks are not worth money. Hens can configure higher. However, CPUs are not interchangeable, and bandwidth is not unlimited. Therefore, resources can only be regarded as theoretical exclusivity at most, but actually more as peak. Anyway, I think so. I won't ask the host company such an embarrassing question. How can they answer it? It's not like saying "exclusive". It's uncomfortable to say "sharing", but the fact is that all VPS share the resources of hens, and it's better to choose independent servers if you have a habit of cleanliness (in fact, I think independent servers strictly mean that the bandwidth is shared, otherwise you can ask how much bandwidth is allocated to one cabinet in the computer room and how much bandwidth there is in one computer room).
8、 Why does my VPS configuration download only 200KB/s of 2M bandwidth?
This 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. If you change it to MB/s, it is divided by 8. For example, the 1M download is 128KB/s. This is still a theoretical value, without taking objective factors into account, and it is normal at 100KB/s. I have to talk about the bandwidth of the 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 100M telecom fiber, so you can download files on the VPS and run 10M/s full? The answer is impossible! 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 downloading from the United States will be affected by factors such as Sino US lines! Yes, you are right. There is really no guarantee (because no one can guarantee the line)!
9、 Is there no limit to what VPS can put? Such as porn and adult content.
If you buy a VPS from a foreign host company, you should determine which content is allowed according to the terms of service. Not all regions can put adult content; If you buy an overseas VPS from a Chinese host company, I can tell you that except for the prohibited content, all violations of Chinese national laws and regulations are not allowed. Although the server is allowed in the country, the Chinese host company is also not allowed! Why, you ask? You are in China, and others are in China. You are not afraid to check the water meter, and others are afraid! Therefore, by doing so, we should not harm our compatriots.
10、 VPS suction? Is there any overseas VPS without ventilation?
This is a joke, at least in my opinion. As I said at the end of each article, "All overseas network products cannot guarantee the same access experience in any region of China, at any time, any broadband. The pursuit of a perfect experience of domestic products is your only choice. Those who claim that a computer room will never take the wind are either liars or fools." I insist on similar statements. Therefore, similar questions do not need to ask the host company, but directly ask themselves whether they can accept it. Any host company cannot solve the problem of lines, which is an uncontrollable factor.
11、 How many people can access this VPS configuration?
There is no answer to this question. The number of visitors is only a part of the factor, and there are many aspects related to PV, web page size, environmental component parameters, optimization degree, and so on. Let's answer this question with the words of boss emshost:
(1) The resources (CPU, memory, etc.) consumed by a static (HTML, JS, pictures, etc.) HTTP request and a dynamic (ASP, PHP, etc.) HTTP request vary from several times to tens of times.
(2) Note that the above is an HTTP request, not a page visit (1PV). The number of HTTP requests generated by each visit may vary several times.
(3) The PV generated by one IP may vary several times. Maybe your website's IP and PV access ratio is fixed, so you can calculate the number of PV based on the IP volume. Even if you can calculate it, it is meaningless. See the above and below for the reasons.
(4) Different website programs have different load capacities. 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 of different dynamic web site programs is relatively large due to the large base.
(5) The same website program consumes different resources with different settings. Take Discuz and DedeCMS for example, the settings related to load in the website background are prompted.
(6) Different Web servers have different load capacities. Generally speaking, the resource consumption of common Web servers on Linux is as follows: APACHE>Lighttpd ≈ Nginx.
(7) The same server environment (Web, DB) and different setting parameters may consume different resources.
*Note: The "same" and "different" mentioned in each of the above are all based on the assumption that other factors are completely consistent (obviously, such assumption is only theoretical, so it can not be used for actual calculation).
For the above reasons, some users want to calculate the required resources based on "the same website program" and "the number of a PV or IP". The answer here can only be that it cannot be calculated.
Finally, I suggest that we should seriously build a regular station and a new station, try our best to choose domestic VPS, file according to the process, and stay away from the trouble of ventilation.
