VPS (Virtual Private Server)
A virtual private server (VPS) is created through the process of virtualization, by which a virtual replica of a physical server is created. A VPS is like having access to your own personal server with an allocated number of resources and choice of a pre-installed operating system. It is an isolated microsystem based on a shared server. Since a VPS is self contained, you have full control of your server setup and are responsible for all updates and security.
Remote access is the ability to access a computer or a network remotely through a network connection. Remote access enables users to access the systems they need when they are not physically able to connect directly; in other words, users access systems remotely by using a telecommunications or internet connection.
