Virtual Dedicated Servers (VDS) and Virtual Private Servers (VPS) are usually mentioned in the same breath and in many ways are equivalent, however there are some differences. Hyper-V virtual dedicated servers offer a distinct advantage over traditional virtual private servers in that they are closer to a dedicated server. In other words they allow the client to enjoy the facilities of a completely isolated virtual machine which has the same type of memory and CPU of a dedicated server, while still being logically separated from the actual physical server.
Hyper-V is able to allow the hosting of multiple OS (operating systems). For instance the same server is able to run both Linux and Windows. This essentially means that virtualization by means of a Hyper-V virtual dedicated server is simpler to scale and more secure because of the isolation from hardware or other virtual machines. Each virtual server performs just like a stand-alone server in terms of both users and applications.
A virtual private server may also be found to be slow at times, this is generally due to the fact that many users are be present on a single web hosting. The speed of the service may also be affected by the applications and software present on the actual physical server. This is able to affect memory allocation and bandwidth. The Hyper-V virtual dedicated server has a new and more efficient design, and the monitoring services provided ensure that the application runs reliably at all times. This makes it a strong choice for both production and development environments, as disaster recovery and server consolidation are supremely efficient. In the event that anything at all goes wrong the support staff is notified immediately to rectify the problem, which is managed remotely.
Some advantages of both VPS and VDS have over dedicated servers are cost, ease of migration, backup, and offline management. Due to the nature of virtual dedicated or private servers, one can very easily migrate from a virtual private or dedicated server to a dedicated server, backup the VDS or VPS server, or even reboot it. A VPS or VDS is suitable to any organization or individual who does not require control over physical hardware.
Due to the shared nature of a VPS platform, it is not recommended to any organization or individual who would not be able to sustain downtime due to updates/reboots of the hardware platform. Hyper-V VDS, on the other hand, is much more reliable and easily rebooted.
