As you may be aware, VPS is an acronym for Virtual Private Server, while VDS stands for Virtual Dedicated Server. Even though both types of webhosting make use of the same type of hardware, they tend to function a bit differently. While most consider these differences negligible, they can have an enormous impact as your site draws more traffic, or needs to make use of more complicated dynamic scripts. Unfortunately, most people that are not aware of their essential differences may wind up spending more money during the upgrade process simply because they chose a hosting provider that does not offer VDS hosting.
What is a VPS Server?
Basically, when your website is hosted on a VPS server, the files are hosted on a virtual machine. Essentially, one computer runs multiple operating systems in order to function like two, or even hundreds of separate computers. Even though all of the virtual “machines” rely on the same CPU and memory, they actually provide faster speed and more room than running a single hardware process.
When it comes to VPS hosting, your files may reside on any number of computers at any given moment, and become accessible through any available channel on the network. While this will not be a problem if you have a low to moderate traffic site, it may become an issue if the server slows down or does not have enough resources to handle such a large volume.

What is a VDS Server?
Even though a VDS server is also run as a virtual machine, some elements are tied to a specific piece of hardware. This may include a special CPU or memory designation. Perhaps it can be said that you can think of VDS hosting as having some of the advantages associated with a dedicated server while still being within the same price range as VPS hosting. In fact, if you do your research carefully, you may just find that a number of hosting companies offer VDS hosting for the same price as VPS. Aside from the advantages associated with smooth run time performance, you can also look forward to fewer concerns about utilized bandwidth.

The Best Server For Your Site
Overall, it can be said that VDS offers a better level of functionality than VPS hosting. If you do not want your site to slow down because of high traffic generated by other sites on the server, then VDS will help you achieve your goal. Unfortunately, you may not always be able to find out if you are actually getting VDS hosting with your plan. Under these circumstances, you might need to test out the system using benchmark applications, as well as other utilities that will help you find out only after you have made your purchase. As may be expected, you can always buy just one or two months of service, run your tests, and then push the domain to another server once you find what you are looking for.
