There are some things that need to be done to make the shortlist.

Including some security stuff like 2FA.

Test includes performance test.

I do not consider VMS heavy weight. When I see how little
that is running on VMS compared to Linux or Windows, then I
consider VMS lightweight. Try count number of processes and
memory usage.

VMS IO may be a pain point. First SSD and a bit of optimized
config. Later some deeper changes.
