1. Cloud Computing
Definition:
“Cloud computing refers to both the applications delivered
as services over the Internet and the hardware and system
software in the data centers that provide those services”.
Cloud Computing Infrastructure
Infrastructure as a service delivers basic storage
and compute capabilities as standardized services
over the network. Servers, storage systems,
switches, routers, and other systems are pooled and
made available to handle workloads that range from
application components to high-performance
computing applications.

3. Cloud Computing Models
Private:
Private clouds are implemented in the enterprise’s data
center and managed by internal resources.
Public:
Public clouds are implemented in the enterprise’s data
center and managed by organization and accessed
by the all kind of users.
Hybrid:
To meet the benefits of both approaches, newer
execution models have been developed to combine public
and private clouds into a unified solution.
