Very much like electric utility time of day pricing, using economic incentives to shift demand to trough periods.
Perhaps an opportunity for them to improve workload scheduling orchestration, like submitting a job to a distributed computing cluster queue, to smooth demand and maximize utilization.
Everything bursty will use economic incentives to smooth the load. I'm not sure how they'd do that with workload scheduling orchestration when you have latency-sensitive loads and there are e.g. twice as many requests at midday as at midnight.
