Self Hosted object storage looks neat!
For this project, where you have 120GB of customer data, and thirty requests a second for ~8k objects (0.25MB/s object reads), you’d seem to be able to 100x the throughput vertically scaling on one machine with a file system and an SSD and never thinking about object storage. Would love to see why the complexity
The complexity for that is almost always for redundancy and for ease of deploys.
(Author here) that's more or less what I have right now – one machine with a file system and an SSD. S3 API on top is there to give multiple web servers shared access to the same storage. I could have used something else instead of S3 – say, NFS – but there was a feature request for S3 [1] and S3 has a big ecosystem around it already.
