This doesn’t happen with VPS hosting because each mini-server has its own allotment of resources. You can’t use more resources than your allotment, but that also means that no other site can take resources from you. Basically, it is like having a smaller size dedicated server without having to pay the hefty ($100 per month or more) price tag that goes with a dedicated server.
VPS hosting costs less and offers more flexibility than dedicated hosting, but semi-dedicated and dedicated hosting services offer more resources. VPS gives greater independence than semi-dedicated hosting though, because once again, the virtual servers on a single computer have no effect on each other and they are almost as reliable as a dedicated server.
Hostwinds reaches that sweet spot of great price, great equipment, and great support with their VPS selection. A VPS from Hostwinds is fully-managed and provides secure, fast, and affordable hosting with no compromising on power or support. The server nodes are never oversold, which provides greater network stability and higher performance. Hostwinds offers a diverse array of VPSs to fit the different needs of each client.
Partitioning a single server to appear as multiple servers has been increasingly common on microcomputers since the launch of VMware ESX Server in 2001. The physical server typically runs a hypervisor which is tasked with creating, releasing, and managing the resources of "guest" operating systems, or virtual machines. These guest operating systems are allocated a share of resources of the physical server, typically in a manner in which the guest is not aware of any other physical resources save for those allocated to it by the hypervisor. As a VPS runs its own copy of its operating system, customers have superuser-level access to that operating system instance, and can install almost any software that runs on the OS; however, due to the number of virtualization clients typically running on a single machine, a VPS generally has limited processor time, RAM, and disk space.
