A virtual private server (VPS) is a virtual computer that an Internet hosting business provides as a service. Customers may have superuser-level access to a virtual private server's copy of an operating system (OS), allowing them to install almost any programme that works on that OS. It's functionally comparable to a dedicated physical server for many applications, and because it's software-defined, it's far easier to set up and configure. A virtual server is significantly less expensive than a physical server of comparable capacity. However, performance may be affected by the workload of any other virtual machines running because virtual servers share the same physical hardware as other VPS. EstNOC is an Estonian web hosting services provider that provides dedicated, cloud, and VPS web hosting services in Norway and 40 other countries along with colocation data center services.
