Virtual server, or VPS, is a category of IaaS, which uses the resources of a physical remote server to manage computing power and storage and offers users the same functionality as traditional physical servers. He executes its own copy of an operating system (OS), and customers may have superuser-level access to its instance. For many purposes it is functionally equivalent to a dedicated physical server, and being software-defined, its able to be much more easily created and configured. They are priced much lower than an equivalent physical server and fully customizable when you order them, with options to scale as your compute needs grow.
