Cloud computing is a type of distributed computing technology. Cloud computing most basic concept is to automatically split a huge cloud computing (雲端運算) processing program into countless smaller sub-programs cloud solutions through the network, and then hand cloud solutions (雲端運算) over a huge system composed of multiple servers will return the processing results to users after searching, calculating and analyzing by the enterprise cloud computing (雲端運算) . Through cloud solutions, network service providers can process tens of millions or even billions of information within a few seconds and achieve network services with the same powerful performance as "supercomputers." Cloud computing is a resource delivery and usage model, enterprise cloud computing refers to obtaining the resources (hardware, platform, software) required by applications through cloud solutions （雲端運算）. The cloud solutions （雲端運算） network that provides resources is called "cloud solutions". The resources in the "cloud solutions" are infinitely expandable in the eyes of users and enterprise cloud computing can be obtained at any time. Enterprise cloud computing feature is often compared to the use of enterprise cloud computing hardware resources like water and electricity, which are purchased and used on demand. Some enterprises are using the enterprise private network to ensure higher security. The enterprise private network provides their internal network for the internal staff to use the private network services. With private network services, the general public cannot access their enterprise private network. Enterprise private network prevent hackers attacking they data. If the company is small and there is limited staff to maintain data security, companies can look for managed private network. Managed private network providers will have staff to monitor the data stored in their managed private network. The internal staff can focus on business goal and let managed private network providers manage the data security.
