| 11 | 4 | Timothée Floure | This page is intended for users that are not familiar with system administration and hope to give them a good stepping stone into this unfamiliar world. There might be some 'simplifications' in order to ease understanding of newly onboarded users: please do not get offusced. Do not hesited to [[CHATting with ungleich|join our chat]] and ask questions! |

| 15 | Ungleich offers various hosted services, from servers to manage yourself to managed services. You can find an exhaustive list on "our product page":https://ungleich.ch/u/products/ but if you're here you likely are interested into our Virtual Machines either at "datacenterlight":https://datacenterlight.ch/ or "ipv6onlyhosting":https://ipv6onlyhosting.com/. |

| 17 | h3. What is a Virtual Machine (VM)? |
||
| 18 | 4 | Timothée Floure | |
| 19 | A Virtual Machine (VM), often mentionned as Virtual Private Server (VPS), is a fully-fledged server. The interesting part is the 'virtual': multiple VMs share a single physical machine, instead of every VM being a physical machine on a shelve. You can have dozens, or even hundreds of VMs on a big physical server: it is often more 'efficient' than having a lot of small physical servers (imagine hundreds of "Raspberry Pi":https://en.wikipedia.org/wiki/Raspberry_Pi). |
||
| 20 | |||
| 21 | One potential trade-off is that if one virtual machine might exhaust the resources of its neighbours by using, for example, a lot of disk IO (input/output: read,write) or CPU (processor). This, however, should not be happening if the service operator is careful and prevent/stop abuses. |
