Cost aside, the answer is mostly “yes, to a point,” but it also depends on which cloud, setup and job type.

They will generally all work just fine if the jobs are independent or loosely coupled. Points of caution include: heavy network or disk I/O - most instances will have limits that lead to bottlenecks at lower usages than most on-premise HPC’s.
