With Spot, if the market price goes above .2x retail, and your job runs long enough then you never succeed with Spot.
By comparison, if you are able to create a preemptible VM you are guaranteed to pay .2x retail and then likely (but not guaranteed) to have 24h to do your work.
tl;dr: A maximum bid of .2x retail isn't equivalent to preemptible. There's almost certainly a bid for a given instance for a given runtime that would result in the same price, but it varies over time, space, runtime and instances shape.
Disclosure: I work on Google Cloud (and launched preemptible VMs)
- williamstein 10y ago> likely (but not guaranteed) In my several years experience using GCE it is indeed extremely likely. Two years ago it wasn't very likely, but it became very likely about a year ago. Incidentally, I'm the guy that convinced Drew Sutherland of this article to use GCE in the first place :-).
