The term Cloud is derived from the use of a cloud shaped symbol used to remove the complicated infrastructure that operates in the back ground.
You purchase your IT as a service and relinquish the responsibility of serving, upgrading and maintaining the system.
Cloud computing has major benefits and can be used to increase the productivity of your work force, form part of your disaster recovery plan or drive down costs with reduced power consumption and the ability to adopt virtual offices making organisations resilient in the current economic climate.
Not only is this revolutionary to the way IT systems are delivered but also appealing to the company accountant with no large capital expenditures, depreciating assets and lower costs of ownership.
