The commitment price is way cheaper: $14.53795/vCPU for n1 vs $10.03/vCPU for e2.

I'm not familiar with GCP, what's the difference between Price vs Preemptible price vs Commitment Price? and where did you get the Commitment Pricing from?

GCP price = AWS on-demand

GCP preemptible = AWS spot

GCP commitment price = AWS reserved instances

Rough comparison. GCP preemptible instances only live 24 hours max and have a set rate, no bidding. GCP commitments are based on CPU/RAM combinations rather than instances. GCP also has automatic sustained use discounts on the normal price if you run an instance > 80% of the month.

Maybe a little off topic: AWS also has savings plans now, which gives a discount based on a commitment of hourly spend on compute. A bit easier to manage than RIs.

You can see the Commitment pricing [1] and a Commitment is a block of vCPUs or RAM you can buy ahead of time and reserve for a year in return for a discount [2].
