How Does A Virtual Private Server Work?

When a website owner chooses to host their site on a shared server, they almost always get a discounted price. Shared servers can host thousands of sites on one machine; these websites all share the server’s disk space, CPU and bandwidth.

Shared resources aren’t usually a problem for small websites; once your site starts attracting a lot of visitors, then it’s probably time to move your site to a different server. Most people start with shared hosting; it’s the perfect way to get yourself online without having to invest in your own server.

When sites start to expand, the owners often need access to their server’s system level software; a growing site’s owner needs to compile new programs, access mail servers and perform administrative tasks. Unfortunately, shared hosting companies don’t give you this level of access. They make it hard to set up spam filters, firewalls and other programs; they put these restrictions on the shared hosting packages to make sure that no one compromises their security.

Owners that want control over their website’s server have an option that is cheaper than buying their own private server; these people can get access to management level functions by purchasing a virtual private server (VPS).

A VPS is a physical server that has been partitioned into a number of virtual machines. The virtual machines act like private servers, but they still share the resources of the server that they are installed on; it’s a combination of shared hosting and private servers. The physical resources like RAM and CPU of the VPS are shared, but every virtual machine acts independently of the other ones. When you buy a VPS, you can install and configure operating systems in any way that you want; you have complete control over your virtual machine.

 

 

A VPS offers a user full administrator access to the root level of the server; this means the person can change anything they want. The person using the server can install and delete software, create user accounts, set permissions and install operating systems. Basically, the user can do everything that they would be able to do on a private server, see VPS by Gigabit Hosting Malaysia.

A virtual private server offers more security than shared hosting. When a person puts their website on a shared host, they share an operating system with all the other users on the server. If a hacker breaks into the root of a shared server, they have access to any site that is hosted on it. Once a hacker gets access to your shared server, they can change anything they want, and you can’t take any measures to stop them.

With a VPS, the virtual machines are partitioned in a way that makes it impossible for hackers to gain entry using just one account. If hackers hack one of the virtual servers, they can’t automatically login to all the other virtual servers hosted on the machine; all the virtual machines are individual servers. The hacker needs to crack every machine on the VPS. When you host on a VPS, your machine is invisible to everyone else; there is no way to set up root access from one machine to another.
