Cloud can be simply defined as a combination of
multiple cloud servers, wherein all works to meet the demands of changing businesses. It helps companies to provision servers, network, bandwidth,
storage space, computers, and other IT components on a pay-per-use model. Right from the servers to networking – everything can be scaled up and cut back when the needs get over. This on-demand IT resource provisioning model provides access to a shared pool of network resources while ensuring maximum network availability for critical business processes. The best thing is that cloud is highly reliable and a fail safe solution when compared to technological solutions. Even if one of the
virtual Machines gets fail in a cloud network, the complete workload gets migrated to other functional servers.
