They have recently introduced per second billing. I don't know how much you
need to use in a second to get billed though.
Might be interesting to run simh on a t2.nano for a month and see what it
costs.

I'll leave it
up to you
which direction you talk me. :D
That could be interesting, but it could also be very expensive. Isn't the AWS pricing based on how much CPU time you
use? The VM I have
running on ESXI is using about 57% of the host CPU. It doesn't matter
to me,
but in a situation where you have to pay for the
resources you use, I
would
think this could be a problem.
BTW, as I recently posted on the SIMH mailing list, I had setup that VM
to
throttle, and forgotten about it. When I moved
from playing with PDP-11
emulation, to actively running Simh/VAX 24/7, it caused major issues,
and a
Raspberry Pi was performing better. Since I
changed that, it's my
fastest VAX.
:-)
I'm not sure how AWS keeps track of CPU usage, but a simh VAX instance
running VMS with idling enabled will normally consume very little host
system
resources unless it is really doing something. When the network is
otherwise
idle, it will wake up briefly once every 10ms to implement a simulated
clock
tick and very quickly go back to sleep.
