What is VPS Web Hosting and the advantages of VPS Web Host ?

Shared web hosting permits many individuals to host their own sites at a very reasonable cost. It has some drawbacks, however. Since many sites can be hosted on one server resources like CPU, disk space, and bandwidth must be shared with your virtual neighbours.

Shared resources are usually not a problem for small to medium sized sites. Your main limitation is the absence of control over system level software : http servers, mail servers etc. You don’t have any choice of operating system and you can not compile programs or do administrative tasks like setting up Spam filters or firewalls.

Many people would say ‘So what? I would prefer not to do that stuff anyway!’ It’s true that the dominant part of site managers have no interest or capacity to handle this type of work and are happy to leave it to the web hosting company. people who need additional management over their server environment or want to experiment with new software, however, can get access to this level of management with a VPS web hosting.

What is VPS Web Hosting ?

A virtual private server (VPS) is a physical server that has been divided (using software) into many virtual machines, each one acting as an autonomous dedicated server. The physical resources like RAM, CPU and disk space are still shared, however every VPS acts independently of the others. Every VPS can have a different operating system and can be configured in any way possible.

The advantages of VPS Web Host ?

The key advantage of VPS web hosting is permitting every VPS administrator access to the root level of his virtual server. This type of access permits the administrator to install and delete software, set permissions, create accounts – in short, do everything that the administrator of a ‘real’ sever can.

As well as providing additional management over your web hosting environment, a VPS web hosting is more secure than shared web hosting. Web sites on a shared server all have the same operating system, so if a hacker were to find access to the root of the server he could damage any or all of the websites on that server. A VPS web hosting, on the opposite hand, is partitioned in such a way that even if a hacker were to gain entry through one account, there is no real way to get to the others. Every VPS is invisible to the others and there's no way to set up root level access from one VPS to another.

Virtual Private Servers might be set up in varied ways so be sure to understand how the web hosting company has allotted resources. The most common configuration is to divide all the physical resources equally by the quantity of accounts. Thus, if there are 5 virtual servers, each would receive 20% of the total CPU, bandwidth, disk space and memory.

The disadvantages of VPS Web Host ?

The disadvantages of VPS web hosting are almost the same as the advantages. The control that a VPS account provides can be dangerous in the event that you don’t know what you are doing. You can delete files, set permissions improperly, permit virus-laden software on the system and, in general, really screw things up. If you don’t have the learning to administer a server, or are not ready to learn, VPS isn't for you.

If your website has outgrown shared web hosting, however, VPS web hosting offers an affordable alternative to dedicated hosting. At the point when looking for a VPS web host, be sure to find out how system resources are divided up, the number of VPS accounts on every physical server, the method for upgrading, and the choices of operating systems.
