@cccc@aussie.zone The privacy friendly (and cheap) option is DIY with Ceph. Managing 100s of petabytes across multiple clusters with it and it's (mostly) smooth sailing.
No way to tell as it depends on all kinds of factors, like workload and IO requirements. For example you could spin up a very cheap spinning rust Ceph cluster for archival use cases or you could have a very fast NVMe/PMEM cluster for compute workloads.
I am managing all kinds of installations.
And before somebody ask no, not piracy related lmao.
(Replying with my lemmy account as my other account apparently isn’t federating with programming.dev)
Basically it allows you to buy or rent your own physical servers and then use the free and open source software Ceph to setup your own cloud storage on top of them.
Depending on the scale you need, it's much cheaper than cloud storage providers, but obviously comes with the caveat that you need to manage everything yourself.
