<p>Xeon etc is probably overkill.<br>
</p>
<p>Use a Raspberry Pi. About 7W under load with a monitor, KB,
mouse w/WiFi active - you don't need a monitor, KB, or mouse once
setup. You can disable the WiFi. (A couple more watts if you use
a magnetic drive, which I recommend).</p>
<p>One time cost is about $100 once you add a case, power supply
& SD card to the $35 board.</p>
<p>For a reasonable workload, that should suffice and is about as
inexpensive to run as you can get. Pi 3 is a 64-bit ARM CPU @1.2
GHz CPU - with 1GB memory, ethernet, WiFi, & bluetooth. (Some
OSs are only 32 bit at the moment.) You can easily scale up with
multiple hosts - it takes quite a number to reach the price of a
Xeon.<br>
</p>
<p>If you stick with standard packages, security is pretty much
one-time setup & periodic package updates (which includes the
kernel). As it's cheap enough to be dedicated to simulation, it's
not a disaster if something bad does happen - as long as anything
else on your internal network distrusts the Pi & its guests.
If you put the emulated OS on the public network, that's a bigger
exposure than the host OS.</p>
<p>If you just provide SSH access, I recommend disabling passwords
and using RSA keys only. It frustrates the script kiddies, and
you don't have to worry about password quality.</p>
<p>Cloud hosting has its own pitfalls. I'm not a fan.</p>
<p>Someone mentioned running on a cellphone. That's tough if you
want remote access because as frequently documented here, WiFi
implementations don't get along with SimH's networking.</p>
<p>Have fun.<br>

<p class="MsoNormal">Dan, it is easy peasy, but not quite
free, as if you want 24/7 access to the box, you have to
keep the system running 24-7, so electricity costs. Plus,
I’m planning on having others log in as well, thus I don’t
want to open up my network like that. That’s why I’m
looking for a free hosted/Cloud solution. That way someone
else can deal with the rest of the network security. I do
enough of that for work anyway, don’t want to have to
monitor my home network as thoroughly. <o:p></o:p></p>
