A virtual private server VPS is a virtual machine sold as a service by an Internet hosting service. The virtual dedicated server VDS also has a similar meaning. A virtual private server 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 it is functionally equivalent to a dedicated physical server and, being software-defined, can much more easily be created and configured. A virtual server costs much less than an equivalent physical server. However, as virtual servers share the underlying physical hardware with other VPSes, performance may be lower, depending on the workload of any other executing virtual machines. The force driving server virtualization is similar to that which led to the development of time-sharing and multiprogramming in the past. Although the resources are still shared, as under the time-sharing model, virtualization provides a higher level of security, dependent on the type of virtualization used, as the individual virtual servers are mostly isolated from each other and may run their own full-fledged operating system which can be independently rebooted as a virtual instance. Partitioning a single server to appear as multiple servers has been increasingly common on microcomputers since the launch of VMware ESX Server in The physical server typically runs a hypervisor which is tasked with creating, releasing, and managing the resources of "guest" operating systems, or virtual machines.

Your web hosting provider installs a virtual layer on top of the operating system OS of the server using virtualization technology. Separating the server into individual compartments with virtual walls, this layer allows each user to install their own OS and software. This means your website lives within a secure container with guaranteed server resources — think memory, disk space, CPU cores, etc. Shared hosting is the most common form of web hosting and works well for many new website owners.

Virtual Private Server VPS is hosting that virtually mimics dedicated server environments within a shared server. VPS hosting has become a popular choice because it is generally lower in cost than dedicated hosting but provides better reliability, security, and performance than shared hosting. Moreover, users get root access to the server, giving them the freedom to install applications and make environment changes without having to go through the hosting provider, as they would with shared hosting. VPS is often a great option for SaaS providers, game makers, programmers, companies that have outgrown their shared hosting, and any company who needs a secure and affordable backup environment.
