Virtual private servers connect shared Web hosting services and dedicated hosting services by filling the gap between them. Because virtual dedicated servers can have their own copy of the operating system, VPS provides the user with super-user privileges in the operating system. VPS enables the user to install any kind of software that is capable of running on that operating system.
I'v tested some other top VPS Providers/resellers (AWS, Digital Ocean, Vultr, etc.) and find that VPSServer.com offer highest performance/price ratio on market. One of the highest (top 3) IOPS, Unixbench and Network perfomance at lowest price from my research. Setting up server with operating systems is matter of few minutes. Managing is simple and clear.
A VPS runs its own copy of an operating system (OS), and customers may have superuser-level access to that operating system instance, so they can install almost any software that runs on that OS. For many purposes they are functionally equivalent to a dedicated physical server, and being software-defined, are able to be much more easily created and configured. They are priced much lower than an equivalent physical server. However, as they share the underlying physical hardware with other VPSes, performance may be lower, depending on the workload of any other executing virtual machines.
