[asperous]

If you haven't used aws a lot then you might not know this but the old instance types stick around and you can still use them, especially as "spot" which lets you bid for server time.

I had a science project which was cpu bound and it turns out because people bid based on the performance, the old chips end up costing the same in terms of cpu work done/$ (older chips cost less per hr but do less).

aws though was by far the most expensive so switching to like oracle with their ampere arm was a lot cheaper for me.
