Virtual Private Server, abbreviated as vps, refers to a high-quality service that divides a server into multiple virtual private servers.
VPS can reinstall the operating system, install programs, and restart the server independently just like a standalone server. VPS provides users with the freedom to manage configurations and can be used for enterprise virtualization or IDC resource leasing.
What is the technical principle of Virtual Private Server?
1. VPS hosting is a server virtualization and automation technology that uses operating system virtualization technology. The concept of operating system virtualization is based on a shared operating system kernel, so that virtual servers do not require additional virtualization kernel processes, resulting in lower resource consumption during the virtualization process, allowing more virtualized servers to be implemented on one physical server. These VPS hosts share hardware, software licenses, and management resources for maximum efficiency. Each VPS host can be restarted independently and has its own root access rights, users, IP addresses, memory, processes, files, applications, system function libraries and configuration files.
2. VPS host is a virtual host implemented by VPS host vmware Server virtualization technology. Virtualization is an abstraction layer that separates physical hardware from the operating system, thereby providing higher IT resource utilization and flexibility.
3. VPS hosting technology supports both Linux and Windows platforms. Virtuozzo Server for Linux also supports different Linux distributions with the same kernel version on the virtual server.
What are the advantages of Virtual Private Server?
1. VPS server is a special server hosting technology between traditional virtual hosts and independent hosts. It virtualizes a large Internet host into multiple server systems with independent IP addresses through special server management technology. These systems have no substantial difference from independent servers in terms of performance, security and scalability, and the cost is only 1/4 or 1/5 of that of renting an independent server. And there is no need to spend extra on subsequent hardware maintenance and management costs.
2. VPS servers have independent system management rights that traditional virtual hosts do not have. They solve the operation and development problems of websites that require independent host performance but do not have sufficient financial resources. It is undoubtedly a more affordable choice.
3. Compared with traditional virtual hosts, VPS servers do not use a large number of virtual hosts to share the same host hardware resources. Therefore, they have obvious advantages in bandwidth, speed, website and email security, etc., and support super administrators to achieve effective remote management, enabling enterprises to more effectively control the CGI programs, databases and other Internet resources they purchased.
4. VPS server is a new Internet business model following the independent server rental service, which is designed for enterprises that are in urgent need of a more complete e-commerce platform but are unwilling to rent expensive independent servers. It has very high practical commercial value, especially for small and medium-sized enterprises that are in urgent need of Internet services.
