Hello! I currently have 3 laptops connected to the ethernet that are acting as three nodes in a cluster, which I can access through a remote web explorer. I want to have open-source storage (like AWS S3) and compute (like AWS-EC2) solutions. For the storage solution, I have installed ceph on each node, created OSDs, pools, monitors, etc. What do you recommend for a compute solution? Can you install Open Nebula on each of the nodes? Is there any other open-source packages that you think are better suited for this?
