There are many advantages on taking out a VPS package or plan when compared to a reseller account or a standard shared hosting plan. The main advantages are all based around the control that having a VPS hosting gives you. On a shared hosting plan or even on a reseller, you only have access to a basic control panel for managing and maintaining your web site. You cannot add / install your own software and certainly can’t configure the server to specifically suit your needs. This is where a VPS comes in.
All VPS packages allow you access to the server configuration files and allow you to maintain the server yourself. By having access to the command line of the server you’re pretty much in full control and can add / remove applications to your hearts content. You can also support your own web server and restart without the need of your web hosts technical support team. This along makes the VPS options a huge draw.
Aside from the technical aspects and advantages of the VPS, you will also find that your websites perform notably better on a dedicated system as opposed to a shared account on someone elses web server.
