Developer program like Red Hat's

Hi All,
I would like to ask if there is a developer program like Red Hat’s ?
I have a dual-socket workstation for a lab and I would like to reinstall it with SLES , but I would like to keep it up to date (and not only for an year) after the 2 month trial.

What are my options , having in mind that I can’t spend any € for subscription and I don’t need any support.

I know that I can use openSUSE , but it’s life is way shorter than SLES .

@strahil Hi look at the SUSE Partner Program, see
