In the IT industry we are initially exposed to the virtual host, with the progress of the times, the demand of the VPS came into being, then the emergence of the current popular cloud host seems so not surprising, the expected era darling, in fact, according to the investigation of some novice users, for the cloud host, VPS and virtual host still have some unclear understanding, next for everyone shaoxing their differences, so that webmaster friends quickly choose the right products!

Cloud Host is a new generation of host rental services, it will CPU, storage and network bandwidth, such as the integration of three services, through a unified platform, on-demand access to services. It effectively solves the traditional host rental price high, uneven service products and other shortcomings.

Although the cloud host has been rising for a long while, but the market still has a cloud host to sell the banner of the VPS products, a very obvious difference is that the cloud host can really get root permissions, users can reload and upgrade the operating system, and the VPS host users do not have root permissions, can not reload and upgrade the operating system. At the same time also remember some of the salient advantages of cloud Host: Multi-node, 0 maintenance, easy expansion, non-stop, etc., the most important is to pay on demand, one months, a year or even a day for the unit can constitute a service.

VPS hosts, all known as virtual Private servers. VPS host refers to the use of Virtual Server Software on a physical server to create multiple isolated small servers. These small servers are so-called VPS, which has its own operating system, and its operation and management is identical to the stand-alone server.

The advantage of the VPS is to ensure that all resources are exclusive to the user, so that users can enjoy the price of a virtual host to the quality of independent host services. A service that divides a server into multiple virtual exclusive servers. Each VPS can be assigned independent public network IP address, independent operating system, independent super space, independent memory, independent CPU resources, independent execution program and independent system configuration. In addition to the user can allocate more than one virtual host and unlimited Enterprise mailbox, more independent server function, you can install the program, separate restart the server.

VPS shortcomings in the same physical server different VPS will affect each other, performance is subject to a single server configuration, and no root or Super Administrator operating system permissions.

The virtual host is to split a real physical server host into multiple logical storage units, each unit has no physical entity, but each logical storage unit can work on the network like a real physical host, each with a separate domain name and a complete Internet server (WWW, FTP, e-mail, etc.) function, each user has its own part of the system resources (IP address, document storage space, memory, CPU time, etc.).

Virtual host between completely independent, even in the same hardware, the same operating system, running for multiple users to open the different server programs, but also can not interfere with each other, in the outside world, each virtual host and a separate host performance exactly the same.

At the same time, the shortcomings of the virtual host is also obvious, if the real physical host failed, then all the above sites are inaccessible.

With the development of science and technology and Internet users for the ultimate pursuit of high-speed and convenient, cloud host will become the trend of the future gradually replace the virtual host and VPS, at the same time from the current London Olympic Games in a large number of use of cloud computing we can also spy out the future of IT development, eight-degree network Take the lead in the cloud host market occupy a place for the internet to open the door of the cloud market to dedicate a force!
