An analytics firm considers moving a nightly batch job from a cloud region in the eastern United States (420 gCO₂e/kWh) to Oregon (80 gCO₂e/kWh, hydroelectric). The job requires a 5-terabyte input dataset stored in the eastern region. Transferring 5 terabytes takes approximately 2.5 hours and consumes network energy. What is the primary constraint that may make this spatial shift impractical?

Question

Accepted Answer

The energy and time cost of transferring the large dataset across regions may offset the carbon benefit of running in a cleaner region

Answer

Cloud providers do not allow workloads to be moved between regions

Answer

Oregon does not have sufficient datacenter capacity to process the job

Answer

Hydroelectric power is unreliable and may not be available when the job  runs
