Open Food Facts uses a cluster to host different virtual machines (VM).
The cluster is made of [[Infrastructure|4 physical machines]]: ovh1, ovh2, ovh3, ovh4.
== Usage guidelines (to be completed) ==
Here is a few guides to follow for all new virtual machines:
# MUST: no direct root access without SSH key
# MUST: indirect root access with sudo, only with SSH connexion
# SHOULD: use SSH keys published on Github: giving access to a server is then simple and secure: <pre>curl https://github.com/CharlesNepote.keys | tee -a /home/charles/.ssh/authorized_keys</pre>
# SHOULD: take care of production resources: use "nice" for scripts manually launched. Stéphane's tip: just use <pre>nice ./mycommand -arg1 foo -arg2 bar</pre> (nice default to lower the priority).
