On-demand capacity is rented by the second or hour with no commitment, at the provider’s list price. Reserved capacity is committed for one or three years at a lower hourly price, paid whether used or not. Spot capacity is the provider’s unused capacity rented at a lower, changing price, which the provider can reclaim at short notice, interrupting whatever runs on it.
