S3 is a truly amazing piece of technology. It offers peace of mind (well, almost), zero operations, and practically unlimited bandwidth for at least analytics workload. Indeed, it's so good that there has not been much progress in building an open-source alternative to S3. There seems not much activity in the Hadoop community. I have yet heard any company who uses RADOS on Ceph to handle PBs of data for analytics workload. MinIO made its name recently, but its license is restrictive and its community is quite small compared to that of Hadoop of its hay days.
Yeah, Ozone looks interesting. I was just not sure who used it at scale other than a Japanese startup. The community engagement seems much lower than other communities, though.
