Ceph
Ceph is a distributed, unified, and resilient network file system. Ceph is developed by RedHat, Intel, CERN, Cisco, Fujitsu, SanDisk, Canonical and SUSE. Its designed to be a flexible storage source that runs on commodity hardware, typically on premises/bare-metal where it can perform well.
Ceph has several key services:
Object Storage: It can do what AWS S3, Cloudflare R2, and Google GCS do, which is to provide data as objects via a public API.
Block Storage: Thinly provisioned block devices that are ideal to run virtualized systems like KVM or Kubernetes.
CephFS File Storage: A global filesystem that can be attached to any service in the network, similar to NFS and GlusterFS
To deploy Ceph you will probably need:
Network engineer(s) with high-speed network hardware and Linux experience
High speed network equiptment, typically in the 100 GbE or greater realm
Beefy Linux system with fast storage like SSD or better
