Tutorial: Hardware requirements for Foreman deployments


unfortunately it’s not easy to plan Foreman deployment as it is very flexible project with many features often coming as plugins. However it is possible to gather some stats about various community deployments to get some rough idea.

Feel free to edit this OP as it’s a wiki page, mark your calendars to return here once per year to update information. When you upgrade, please create a new record in the table so older versions are kept for comparison. Thank you!
