This is Cloud Hosting
With cloud computing you have an access to computing power instantly when you need it. Put your website on a cloud server that you have and it will put it in a dedicated server. And when people visiting your site.. if you suddenly need more computing power in dedicated to your website, you can scale up as much as you need instantly.
This is the major advantage, so I said it once again when you need more computing power you can get it instantly from the cloud. And when you are done with it, you release it back to the cloud.
Cloud computing comes into focus only when you think about what IT always needs: a way to increase capacity or add capabilities on the fly without investing in new infrastructure, training new personnel, or licensing new software. Cloud computing encompasses any subscription-based or pay-per-use service that in real time over the Internet, extends IT's existing capabilities.
You never actually touch it physically
A public cloud computing sells services to anyone on the Internet. A private cloud computing is a proprietary network or a data center that supplies hosted services to a limited number of people. When a service provider uses public cloud resources to create their private cloud, the result is called a virtual private cloud. Private or public, the goal of cloud computing is to provide easy and scalable access to computing resources and IT services.
Think about like you would use any cloud service. Do you really care where and what physical server your emails hosted? Is not how the service works more important? Is it reliable, stable, and easy to use?
A cloud computing can be private or public.
