Disclosure: I used to work on GCE.

We got to go second, but I prefer the naming and separation of concerns we came up with (obviously): Reservations are capacity you're holding, while Commitments are things that get you discounts.

Reservations are things your operations team uses to guarantee capacity for scaling up, doing rolling restarts, and whatever else. Commitments (and Committed Use Discounts) are primarily what your Finance teams work with.

The original Reserved Instance product combined both of these. AWS now has the same decoupling with Savings Plans and Reservations as related, separate products.

I’m not familiar with GCP but those names/concepts are easy to understand and I like the separation of concepts.
