Personal cloud is a collection of digital content and services which are accessible from any device. The personal cloud is not a tangible entity. It is a place which gives users the ability to store, synchronize, stream and share content on a relative core, moving from one platform, screen and location to another. Created on connected services and applications, it reflects and sets consumers’ expectations for how next-generation computing services will work. The four primary types of personal cloud in use today are: Online cloud, NAS device cloud, server device cloud, and home-made clouds. ==Online cloud== The online cloud is also sometimes referred to as public cloud. Online cloud is the cloud computing model where online resources like software and data storage are made available over the Internet by a service provider. In an online cloud model, cloud services are provided in a virtualized ecosystem, are constructed using pooled, shared physical resources and are accessed by the Internet. Typically, an individual or organization has little control over the ecosystem in which the online cloud is hosted, and the core infrastructure is shared between many individuals and organizations. The data and applications provided by the service provider are logically segregated so that only those authorized are allowed access. Some examples of online cloud products include Google Apps for Work and Microsoft's Office Online (both providing a range of applications, including e-mail, calendering, office productivity applications and file storage), Dropbox (which focuses mainly on file storage and sharing), Box, Funambol, and Basefolder. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Personal cloud」の詳細全文を読む スポンサード リンク
