Private Cloud with OpenSource – "Now for Real!"
summary
A production private‑cloud built as an AWS replacement using Ubuntu, OpenStack and Ceph (including an S3‑compatible gateway) is described, running 10 months in production on OpenStack controllers, compute nodes and four Ceph nodes (~175 TB raw). The talk covers concrete problems and fixes: exhaustive baseline benchmarking, network bonding failures traced to switch firmware, Ceph scrubbing I/O storms, live‑migration patches, and lengthy firmware upgrade issues; deployment required nine months of work by two people plus heavy manual debugging and ongoing maintenance.
