What is the VPS, its purpose and advantage?
What is a VPS?
VPS, Full name is Virtual Private Server, a physical machine more than create separate from each other’s Virtual Private servers, because every VPS all can independently to restart and has its root access, users, IP address, memory, process, documents, application, system function library as well as configuration files, so each operation and management of the VPS platform with a independent host completely the same.
VPS technology principle:
In ordinary server original operating system installing special software, the software can put the hardware Virtual segmentation out, generating a small number of Virtual Machine VM (Virtual Machine), these VM and our common calculation, initialization some hardware information, again in the VM installed on the corresponding operating system and service system can generate a Virtual server, and we put these servers collectively referred to as Virtual private servers. Because virtual private servers can achieve a variety of network application service, so we call VPS (virtual private servers).
Second, VPS can do?
VPS (virtual private servers) operate as independent of the server, have all the power of the system (this is the biggest difference between the host and virtual). The administrators can VPS completely control and the configuration of the “server”. For your own free users with CGI program, install the dynamic module, adjust their own database, and so on.
VPS USES:
General speaking, VPS (virtual private servers) is mainly used in the following aspects:
VPS (virtual private servers) for its economy, small and medium-sized businesses usability has become electronic business, online trading the most ideal server operation platform;
VPS (virtual private servers) has been many small and medium-sized industry portal or scale of the relatively large personal site as a web server platform of choice, cost-effective;
VPS (virtual private servers) with its extensibility, stability, and increasingly large and medium-sized enterprise web portal, or internal BuMenJi the application of information technology server platform;
VPS advantage:
VPS (virtual private servers) is a cross between a traditional virtual host and independent of the special between host server hosting technology, it through the special server management techniques to a large Internet host virtualization into multiple independent IP address server system, the system no matter from performance, security, and expansibility and with independent server has no substantial difference, and the costs is only 1/3 of the rent independent server, and without the extra expenses subsequent hardware maintenance management cost.
VPS (virtual private servers) have traditional virtual host doesn’t have the system independent right, to solve the need to have both independent host performance and financial resources and not enough website operation development issue, it is a kind of more affordable choice.
Compared with the traditional virtual host, VPS (virtual private servers) because not to use plenty virtual host share the same host hardware resources situation, so in bandwidth, speed, website and email security which are relatively obvious advantage, and support the super administrator realize effective remote management, the enterprise can more effectively control of buying their own a CGI program, such as the database of the Internet resources.
