comment EXT4 Single Larger Volume or Many Smaller Volumes
'structured file-serving' is something like Sharepoint or another document management system. Unstructured is a big mass of excel, word, powerpoint, random images, and whatnot.

comment Parallel Processing and Disk IO for performance. More cores or more servers?
@monkeymatrix Good question. In general, scaling single-threaded processes goes mostly-linearly assuming the only contended resource is CPU. These days one-big-box scales more efficiently than lots of little boxes, but you can scale farther with lots of little boxes. Lots of little boxes won't be AWS-cost-efficient though.

comment cURL is failing for normal users but not root
At a guess, and it is just a guess, /etc/pki/tls/certs/ca-bundle.crt is owned by root and not world readable.

comment Meaning of directories on Unix and Unix like systems
@Pacerier It's a filesystem, but may be safely mounted as a RAM-disk. That said, many programs assume a set structure in there, so actually require persistence.

comment SAN with a few SSD drives, or lots of old fashioned HDDs?
@Beepbeep Yep, but be aware of the tradeoffs. Lots of iops will consume controller resources, which means you won't get max sequential throughput from the HDDs. Lots of sequential throughput on the HDDs can crowd out IO from the SSDs increasing latency due to channel contention. If that matters to you, but them on different channels.
