True, although there is a dev overhead and there are other issues (cold starts, unpredictable bills, zero control of the runtime, vendor lock-in, etc).
As a person running a service, I only care about fairness of resource allocation if my service isn’t getting at least its fair share. As an ops person, you know that if I am not getting my fair share it’s because someone else is misbehaving. As a functioning adult, you understand that if you are getting more that you should, it’s coming at someone else’s expense. Because fairness isn’t being enforced.
A lot of complexity we add to these systems is about fairness. Fair is always about narrowing the gap between best and worst case run times and trying to keep the result close to expectations, and being able to defend it when they don’t match.
