Cloud computing is the use of computing resources (hardware and software) that are delivered as a service over a network (typically the Internet). The name comes from the use of a cloud-shaped symbol as an abstraction for the complex infrastructure it contains in system diagrams. Cloud computing entrusts remote services with a user’s data, software and computation. -From Wikipedia, the free encyclopedia
Wow that is confusing, huh? Let me make it simple. Imagine your PC and all of your mobile devices being in sync—all the time. Imagine being able to access all of your personal data at any given moment. Imagine having the ability to organize and access data from any online source. Imagine being able to share that data—photos, movies, contacts, e-mail, documents, etc.—with your friends, family, and coworkers in an instant. This is what personal cloud computing promises to deliver.
In essence, personal cloud computing means having every piece of data you need for every aspect of your life at your fingertips and ready for use. Data must be mobile, transferable, and instantly accessible. The key to enabling the portable and interactive you is the ability to synch up your data among your devices, as well as access to shared data. Shared data is the data we access online in any number of places, such as social networks, banks, blogs, newsrooms, paid communities, etc.
I hope this clears up any confusion about “The Cloud” and ultimately I think this technology is a great advancement and we will all head towards the cloud eventually.
