In today's world of the internet, it's hard to actually imagine a company of a good size that does not have its own website. As a result, having a server to host everything on, ranging from your product catalog, to occasional user manuals, high resolution images of your products, and even the design of the website along with all the code that makes it run becomes an essential step in the process of actually having your own website. There are several types of web servers out there that you can procure, but we're going to talk about the Linux based types.
The basic need of any web server is for it to be stable, because your website is essentially not accessible unless your web server is up and running. Stability being an important characteristic of any web server, it's no surprise that the rock solid, UNIX based platform of Linux is a popular choice. Linux servers generally run Apache, a version of the Linux OS which is specifically geared towards running web servers. This OS is actually the reason that a majority of websites on the internet actually run Linux, because you can completely customize the web server and have a Linux Unmanaged web server up and running quickly.
There are several companies out there that can not really afford their own dedicated web server, or just do not want to spend such a large amount of money on a website, yet they need the correct amount of flexibility to not be tied down by the server . For these people, a Linux VPS may be the perfect option. A Linux Virtual Private Server basically is a server which is the middle ground between shared and dedicated servers. The server itself is maintained by a third party, but you are essentially given a share which can run it's own Operating System and be rebooted independent of the other partitions on the same server that are present.
There are several benefits with a Linux Virtual Server that are true of all Linux installations in general. Linux has always been proven to be really solid operating system that rarely crashes, and this is a major plus in all kinds of web servers. Another huge benefit is that by and large, Linux is a very secure operating system as it is community managed, and then bugs are reported and fixed extremely quickly. One minor downside of Linux is that since it is at the end of the day an open source operating system, targeted attacks on your server will be more likely to be successful.
Many people feel that a disadvantage of Linux servers is the lack of support that is offered as it is a community driven OS. This is not a real disadvantage because some companies such as Red Hat provide professional support at a small cost. At the end of the day, a Linux server offers several advantages such as stability, a reduction of costs, and increased security that it is the best option for several people.
