Personal cloud


A 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.

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 system, 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.

A network-attached storage (NAS) device is a computer connected to a network that provides only file-based data storage services to other devices on the network. Although it may technically be possible to run other software on a NAS device, it is not designed to be a general purpose server. Cloud NAS is remote storage that is accessed over the Internet as if it were local.

A cloud NAS is often used for backups and archiving. One of the benefits of NAS Cloud is that data in the cloud can be accessed at any time from anywhere. The main drawback, however, is that the speed of the transfer rate is only as fast as the network connection the data is accessed over and can therefore be fairly slow. An example of NAS personal cloud is the My Cloud by Western Digital, the CloudBox by Lacie, and the Central by Seagate.
