Unfortunately completing this flow - with the goal to get a temporary shell on a Power system running some Linux distro - requires me to authorize a payment of over 1300 dollars before I even select an image. That's for "reserving" 1 POWER core and 2GB of RAM... As an individual developer playing with this, that's way over my head. I'd understand very high end cloud pricing for that (tens of dollars per hour, I'd be happy to pay that for messing around a little), but this isn't even a cloud machine pricing model. For reference, $1300 is over half the price of getting a Talos motherboard with an 8-core POWER9 CPU you then actually own.
It seems IBM does not have the infrastructure or volume to permit cloud pricing here. I understand they might not have this, but in my opinion they need to work on this to make it accessible.
