As you know there are a lot of computational centers working with CentOS. Sometimes because it is the best OS sysadmin knows, sometimes because of a low budget problem.
Now we have this important change, so we have to decide. We have to choose the OS we are going to install in our servers, moreover we have to decide as quickly as we can, because as you know changes should be done as calm as posible.
If I were in your shoes ( actually I AM in the same situation except that on a much lower scale ) I'd wait 4-6 months until we see the plans for the new subscriptions that RH will announce in Q1 2021.
It is a good point, we can wait. The problem is when you have a lot of computers and no budget to be used in OS.
As has been reported, you can use RHEL in the front servers, and Fedora in the cluster itself. The problem is to have a real software compability. When having a lot of users, working with their own programs, you have to be sure everything is going to work. However they are going to compile the programs "with poor knowledge" in the front servers, and they will have problems when using the binaries in the Fedora systems...
Could we list pros/cons about using CentOS stream in a computational Center?
Pro: will always be ahead of RHEL, with all new bugs and features
Con:will always be ahead of RHEL, with all new bugs and features
;-)
Are we going to see CentOS stream in the top500 list?
I am willing to bet a case of Estrella Damm on "Never". Those machines usually require a more stable env. As I see it (I might of course be wrong, it would not be the first time), Centos Stream seems to be more intended to developers and people looking to be on the front end of using new features and bugs.
That is the point: developing system vs stable system.
