I think SPOT (pre-emptable) instances are an under appreciated resource in AWS. Technically they can get pulled back at any time but in practice it’s only happened to me once, for a single instance. I’ve lost far more instances to hardware failures in the same period. If you can get your head around that then you can save more money with SPOT plans then any of the regular compute plans. AWS also does an auction for SPOT instances which can push the price really low for ARM and previous generation instances whereas other clouds just give you a set discount when using them.
