CTO-Technology Article 3 (selection of virtual hosts)

In order to put my website on a good server, I once put the server on a different place. In fact, it is very easy to transfer the website. Just upload the webpage and export the database. Unfortunately, I have never used joomlapack. It is said that this is a good tool.

I tried a foreign offees website for free, but the Panel often fails to wait. I reported that the server of this VM is already full, I was unable to log on to my management interface to manage my website. Later I tried haoduola and talked about the CERNET line. It was very slow to open in Tsinghua, and the service attitude was very good; my friend introduced idcbc quick data, which provides good services, but the education network is still slow. Finally, I had to select my brother's server. Of course, it can also be placed on Tsinghua's server, but it is said that commercial websites will be blocked.

I found a selection article to repost:

Foreign virtual hosts have many advantages over those in China. For example, they do not need to apply for an ICP filing. The price is relatively low and the stability is good. Although the access speed from China is a little slower, but it is indeed a low-cost Creation
Good website solutions. The foreign space is basically based on Linux + Apache + MySQL + PHP. Because PHP has actually ruled the standards of the website design language
You can stop using ASP.

However, foreign virtual hosts are still mixed, and even some well-known virtual host providers are getting bored. I have been buying foreign virtual hosts for a long time.
During the time when the English guest website was using foreign virtual hosts, it also encountered various unexpected problems. Therefore, I would like to summarize some methods to purchase and identify foreign excellent virtual hosts for your reference.

The principle of a VM is to divide a real host into many
Virtual Hosts, which are completely independent from each other, allow multiple users to share the resources of a real host, saving users' hardware fees and traffic fees. Generally, the price of a VM is about 5 to 10 USD per month.
Usually low. In order to obtain the greatest benefit from limited servers and network resources, virtual host providers must infringe on the user's interests and oversell (overselling) Virtual Hosts. Therefore,
A stable and excellent VM can be selected only when overselling is identified.

How to identify over-sales (overselling) virtual hosts is summarized here:

Tricks on capacity and traffic parameters

The vast majority of overselling virtual host providers are playing a digital game, less than 10 dollars a month, you can buy large capacity and traffic host, its capacity and traffic parameters are often
Traffic is larger than renting a server. For example, the monthly traffic of the independent server's moonlight blog is only 450 GB, and almost all overselling virtual hosts claim to be able to provide
Of course, this promise will never be fulfilled if you have a website with a traffic of more than GB per month, so you absolutely cannot consider these overselling virtual
Host, because when you have not used about 1% of the traffic, these VM providers usually terminate your service on the grounds that they have used too many resources, the deceived users do not actually realize the huge space.
Traffic is different from the CPU and memory resources used. If you use a lot of traffic, the host service provider will not terminate the service on the grounds that the excessive traffic is used and the excess CPU and memory resources are used.

Risks of annual payment

Almost all overselling VM payment methods are based on annual payment. Either they only support payment by year, do not support payment by month, or pay by month
The price differs greatly from the price paid by year, forcing users to choose to pay by year. Why are these host vendors doing this? Because their way of limiting CPU and memory will certainly cause users to not purchase the virtual host
Satisfied, the user will definitely terminate the payment and reselect the host provider. If you find that the host is slow or the service is not good, you can stop the payment next month and choose another host. For individuals
The risk is small and there is no loss. If you pay by the year, you will not be refunded and the cost for one year will be lost. In this way, Vm providers force users to spend an extra amount of money and earn money. Normally
Non-overselling formal and confident host providers are willing to provide monthly payment methods, and the price paid on a monthly basis is not very different from that paid on a yearly basis.

Rewards

In order to expand the user base, overselling virtual hosts will be promoted in the form of kickback rewards or cash return, that is, the user recommends a new host to register a user. The recommender can
To get a reward or kickback, similar to a pyramid scheme. These activities basically belong to overselling virtual hosts. They did get a large number of users in this form, but their hosts
The quality will decrease as the number of users increases.

Number of domain names that can be bound

Overselling virtual hosts provide almost unrestricted domain name binding. A user can bind countless websites to a virtual host, which many people like. But we
You must know that the resources of a server are limited. The more websites you bind, the more resources you consume. The result is that the website's response speed and stability are reduced, 500 Errors often occur, for example
Virtual hosts have been bound to more than one thousand ftp users. Can such virtual hosts be used? Therefore, a formal VM provider can bind one or two domain names to ensure the interests of most users.

The above are some of the techniques I have summarized to identify over-sales (overselling) Virtual Hosts. If you are using WordPress or forum, it may reach daily
10 thousand IP access, so it is best not to select the overseelling virtual host, because their CPU limit will cause extremely unstable Website access. Of course, if you have many small websites or websites
All are in HTML format, and PHP and MySQL are rarely used. You can also choose overselling virtual host, because the pure HTML page consumes a small amount of CPU and does not produce a large negative value.
Load. Otherwise, it is best to select a virtual host that limits traffic rather than the CPU.

The recommended non-overselling VM is usually priced from 5 to 10 USD. The traffic limit is less than GB per month and one or two domain names are bound. This parameter usually does not limit the CPU usage of virtual hosts. It is suitable for dynamic PHP websites with a daily access volume of more than 10 thousand IP addresses.
