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.

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.
