Jumped in to try it out.

In US we get $200 promo credit and at the VM rental page I see 2 viable options:

The one you list is D4S_V3 for $143 for 4 CPUs.

I also see a B8MS for $252 for 8 CPUs.

Any idea on the profitability of the 4 CPUs you suggested? Trying to see if it's worth to go for 8 for less than 2x the rental price.
