Embracing Ceph: Key Factors Driving Companies to Adopt Ceph Storage Solutions
summary
Organizations choose Ceph because it delivers block, file and S3 object from one system, scales to 300 PB/year for SKA-class ingest, and powers a private cloud serving thousands of engineers and hundreds of HPC nodes. Deployments use RBD, RADOS Gateway and Ceph-Ansible, teams contribute features like CSI encryption and fix bugs (one kernel bug caused MySQL reboots for ~40 customers). Migration paths migrated VMs without downtime work, but hardware choices, countless tunable knobs and sparse beginner docs remain the main hurdles.
