Virtual host, also known as "website vacancy", divides a physical server running on the Internet into several "virtual" servers. Virtual host technology has greatly promoted the application and popularization of network technology. At the same time, the virtual host rental service has become a new economic form in the network era. There are nearly 65438+ billion computers connected to the Internet. No matter what model, operating system and software they use, they can be divided into two categories: client and server. You can ask Alibaba Cloud, and the consultant will tell you, and you will understand.
Client: A client is a machine that accesses other hosts. When surfing the Internet through ISP (Internet Service Provider), the client will be assigned a temporary IP address. With this temporary IP address, the client can get information from the Internet. After the network is disconnected, the client leaves the Internet and the IP address is taken back.
Server: Servers refer to those computers with strong computing power that can be used by multiple users, usually called hosts. There are many differences between server and client. For example, a client usually serves only one user at a time. Users use clients through terminals, and clients use servers through networks. Compared with the client, the server needs to work continuously for 7×24 hours. This means that the server needs more RAS (reliability, availability and serviceability), such as supporting the use of ECC (error checking and correcting) memory. Virtual host technology is a technology used by Internet servers to save server hardware costs. Virtual host technology is mainly applied to HTTP (Hypertext Transfer Protocol) service, which logically divides one or all service contents of a server into multiple service units and presents them as multiple servers, thus making full use of server hardware resources.
What is the use of cloud hosting?
Cloud hosting is a large-capacity cloud hosting collection, with multiple servers providing load balancing and dynamic allocation of resource websites on demand. It is suitable for websites with more websites or website construction companies, and has better performance and cheaper price than VPS.
When using cloud hosting, you don't have to worry about server security or configuration. It is as convenient to use as a virtual host, and the load can be as strong as a server.
What is host space?
In fact, the host simply means storing the content of the website and hosting the space of the website. When someone wants to see your website, they will first enter the domain name in the browser, and then their computer will be connected to your host space. At this time, the web content in the host space will be delivered to them through the browser.
Host space can be classified according to the technologies used by servers, such as virtual host, VPS, private host and cloud host.
It can be classified according to the website building program, such as WordPress host, Drupal host, Joomla host and Magento host.
It can be classified by server, Linux host and Windows host.
It can also be classified by program language, PHP host and ASP host.
Of course, it can also be classified according to the purpose, such as blog host, foreign trade host, enterprise host and so on.
Or by country, China hosts, American hosts, Indian hosts, European hosts, Japanese hosts, Korean hosts and so on.
No matter what kind of hosts, foreign trade websites can only use paid hosts, and all hosts under the banner of free can't.
What's the use of main space?
The main space of a computer carries two basic functions:
Store the documents of the website and provide the environment for the website to run. The host space mentioned here is actually a server connected to the public network, which basically runs 24 hours, and the hard disk of the server can store website files; You can run the website by installing a system and environment on the server.
Common host spaces in the market are Windows host and Linux host:
Windows host, as its name implies, is a server version of Windows system installed on the server, such as windows2003. This kind of host usually uses its own IIS to configure the environment in which the website runs. Windows host, often called universal host in the market, supports website building programs written in languages such as ASP and PHP. Of course, MySQL database environment is generally installed.
What is the function of website space?
Nowadays, some cyberspace is free, while others are charged, and the latter provides users with better services.
After successfully applying for cyberspace, you can put the produced web pages, forums, etc. In the space, let more people visit or know your works. You can also think of cyberspace as a private USB flash drive. How big is the storage space of the website server?
Opening/original poster
Hello, I'm glad to answer your question. When choosing a space, you must know your website very well. Depending on your website, you can determine the size and type of space to use. The capacity of a server is determined by the hard disk, and different sizes of hard disks can be configured according to different needs.
If it is the company's product display website, a virtual host or VPS will do. Generally, the website space of a company is about 500M, in case there is not enough space for uploading data. If it is a portal website or mall website with a large amount of information and pictures, try to choose VPS or server. Generally speaking, the capacity of VPS ranges from 20 to 40g. If your website is a download and video music station, I suggest you use an independent server, because such websites require high bandwidth and configuration.
The above is my personal opinion. If you have any questions, please contact me.
