Could you explain the rationale? I understand and fully agree that sustainable funding and maintenance for infrastructure are key topics for the project. Do we need to move ci.guix soon? Related to Ricardo announcement [1]? Well, I am missing some context or steps. Currently, the project is mainly in Option #3 (sponsored). The main sponsor is MDC located in Berlin. The second sponsor is personal funds coupled to hardware bought by us or donated to us =E2=80=93 I have in mind the build farm behind the n= ame Bordeaux; thanks Chris! And the third sponsor =E2=80=93 at some extent =E2= =80=93 is Inria located in Bordeaux. We had discussions about reinforcing the second sponsor by replacing personal funds by project-wide funds, say Guix Foundation, community, etc. Is this description correct? > The various options and back-of-the-envelope estimates we came up with > are as follows: > > 1. Buying and hosting hardware: > 250k=E2=82=AC for hardware > 3k=E2=82=AC/month (36k=E2=82=AC/year) > > 2. Renting machines (e.g., on Hetzner): > 6k=E2=82=AC/month (72k=E2=82=AC/year) > > 3. Sponsored: > get hardware and/or hosting sponsored (by academic institutions or > companies). Well, on the paper, option #1 appears to me appealing but how do we get this 250k=E2=82=AC? Somehow, 250k=E2=82=AC would mean being able to secure= 3k=E2=82=AC/month for over almost 7 years, right? Except if we have a large donation that I am not aware, I do not see how it would be possible to sign in being sure to secure 3k=E2=82=AC/month for = over almost 7 years; considering the project has 12 years. Other said, option #1 does not appear to me an option. Option #2 could be a temporary option for a short time. But again, that=E2=80=99s something. > Option #3 potentially gives less control (depending on the project=E2=80= =99s > relation with the hosting organization) and makes the project dependent > on the sponsor and/or person(s) in touch with them. On the upside, it > could significantly reduce costs (potentially to 0=E2=82=AC). It remains option #3. :-) For me, that=E2=80=99s the only viable option at scale. The main costs sho= uld be covered by sponsor as academical ones. From my point of view, the only sustainable option is to group people behind GuixHPC (I recall the domain name hpc.guix.info is paid by Guix Foundation ;-)) and ask: a) if their institutions are ready to donate and/or a) if we could run for some grants altogether. Somehow, Guix starts to be run in various scientific data centers and we could take advantage of this opportunity. Indeed, it locks in some relation with the hosting organizations and/or the person in touch with them. That=E2=80=99s said, Ricardo showed it works well =E2=80=93 or at least it can. :-) The key appears to me to not put all= the eggs in the same basket. That=E2=80=99s my half-baked current opinion. WDYT?
