you scale up the query cluster for the month-end run and the data does not move anywhere.

Storage-compute separation

Also calleddecoupled storage and compute, disaggregated architecture

Keeping data in shared storage that any amount of independently scaled compute can read. It is the architectural change that made elastic warehousing possible: compute can be sized per workload, several workloads can read the same table without copies, and storage is billed at object-storage rates. The cost is that every read crosses a network, which is why local caching, file layout and pruning matter so much more than they did on tightly coupled systems.
