The websites we visit on a daily basis are composed of domain names, website source programs, and hosts, which are servers that store the source code of the web pages and are able to display the contents of the pages to the user. At the end of this book, Mr. Liu Wei talked a few more words about the server host knowledge and shopping skills, these skills are in recent years to do the website summed up, hoping to help everyone.
Virtual host: divide a certain amount of disk space in a server for users to place website information, store data, etc., provide only the basic website access, data storage and transmission functions, can greatly reduce user costs, and almost no user to maintain services outside the website, suitable for small websites.
VPS (Virtual Private Server, Virtual Private Server): Virtualization technologies such as OpenVZ, Xen, or KVM simulate multiple "hosts" (i.e. VPS) in one server, each with a separate IP address and operating system; Suitable for small websites.
ECS (Elastic Compute Service, Cloud Server): is a compute service that integrates computing, storage, and networking to scale elastically;
Stand-alone server: This server is only available to the user for one person, and its use is divided into rental and hosting methods. T he lease is when the user informs the IDC service provider of the hardware configuration requirements of the server and rents their hardware equipment on a monthly, quarterly, and yearly basis. T hese hardware equipment by the IDC service provider's room is responsible for maintenance, users generally need to install the appropriate software and deploy website services, which reduces the user's investment in hardware equipment, suitable for large and medium-sized websites. H osting is when the user needs to purchase the server hardware devices themselves and hand them over to the IDC service provider for management (management service charges apply). Users have full control over the server hardware configuration, strong autonomy, but need to maintain and repair the server hardware equipment, suitable for large and medium-sized websites.
It is also important to remind the reader that when selecting a server host vendor, be sure to pay attention to the word-of-mouth and make a decision to purchase after a comprehensive analysis. Some suppliers will have restrictions, forced advertising, hidden deductions or mandatory charges and other bad behavior, please readers must polish their eyes, do not be taken seriously!
