The terms VPS (virtual private server) and VDS (virtual dedicated server) are often used interchangeably. While quite similar and equivalent in many ways, there are some notable differences. Hyper V, the virtualization software used to power most virtual dedicated servers, offers a level of power closer to that of a dedicated server, giving it advantages over the traditional VPS environment.
The VDS Advantage
A virtual dedicated server provides the facilities of a completely isolated virtual server. One of the major differences it has in comparison to a VPS is the ability to run multiple operating systems. For example, a server equipped with Hyper-V could run Linux, Windows and FreeBSD to suit the needs of different customers. The mere structure of a VDS creates a platform that is easier to scale, as it is isolated entirely from the actual hardware and other virtual machines. Each individual server performs like a stand-alone machine in virtually every aspect.
A VPS does offer better performance than a traditional shared hosting platform, but is prone to more performance issues than its VDS counterpart. This mainly occurs when a multitude of users are hosting on a single machine. In this environment, bandwidth and memory allocation can be affected by other virtual servers, whereas a VDS ensures that these resources are available, just like having your own server.
Two Excellent Options for Virtualization
The major similarity of VPS and VDS is a cost efficiency that makes them considerably more affordable than having a dedicated server. Both are easier to use and give you an incredible level of control and flexibility. Though VDS is the more reliable option, both offer power that towers over traditional hosting solutions.
