Cloud computing makes use of the excess server capacity of specialized providers. Your work may be split among many machines, sometimes called virtual servers, that also work on the tasks of other individuals or companies. (Software-as-a-service, often confused with cloud computing, is a subset of it.) Cloud computing can help small businesses ease capacity issues such as the ones BrickSimple experienced. You don’t need to invest in your own servers or employ staff to take care of them. Instead, you pay only for the capacity you need at a given time. And as demand rises, capacity increases without interruptions.
