What is the best OS to use to create a cluster?

Question

Clusters

There is a question about choosing an OS for creating a cluster using ISPmanager Cluster.
If anyone had or has experience in this direction, I will be happy to listen and take into account.
Thank you.

Answer 1

definitely Linux - CentOS / RHEL (paid) or Debian. If you are not going to buy RHEL, then I would choose debian, it seems to be more stable than centos.

Answer 2

linags.

Answer 3

Depending on the availability of specialists. This is absolutely the dominant criterion.
If for some reason this is not a problem for you, then the choice should be made between Frey and Linux, which are basically equivalent, and here you already need to look for what you will need this cluster for.

Answer 4

I would choose CentOS. For this is Free RHEL and there is a lot to read.
What is a cluster? HA-LBC? Or just HA?

Answer 5

Sun Cluster Geographic Edition :) But I also liked the perfect product for small clusters.

Answer 6

CentOS/RHEL is the best option. I would not choose Debian, I did not see cluster management out of the box.
Freya - no.
