You might imagine it as a main arbiter who assigns performance and physical server memory to individual virtual servers, whilst, at the same time, separating the servers from each other. Its pivotal component is a hypervisor which monitors and controls the VS running straight on the hardware level. Graphical Representation of Full Virtualisation (left) and Operating System-Level Virtualisation (right).įull or in other words Native Virtualisation is a virtualisation in the true sense of the word. Obviously there exist many other partial virtualisations which virtualise only some of the hardware instances (memory, processor, network card), however these are not the subject of this article. To serve the purpose of this article, it is sufficient to introduce the two basic types – full virtualisation and the virtualisation on the OS level. There exist several sorts of virtualisation that differ particularly in their extent and level on which the virtualisation is conducted, which has a fundamental impact on the VPS features such as scalability, and/or the OS compatibility. Before we start with the technologies concerned, first let’s discuss what virtualisation types actually exist and what their general dis/advantages are. Which is why we decided to explain how the virtualisation itself works, whilst focusing on KVM and LXC that are commonly used in Master DC for virtualisation servers with Linux OS. It is considerably hard to understand all parameters and technical details of VPS.
