h1. Datacenterlight (and IPv6OnlyHosting) beginner's guide
This document is *a DRAFT*, there's a lot of *WORK IN PROGRESS*.
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!
h2. What am I here for?
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/.
h3. What is a Virtual Machine (VM)?
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).
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.
