Question

Explain in detail about cloud computing.

Answer 1

1. Cloud computing is the on-demand availability of computer system without direct active management by the user.
2. There are three primary service models of cloud computing that are Infrastructure as a Service (IaaS), Platform as a Service (PaaS), and Software as a Service (SaaS).
3. Infrastructure as a Service (laaS): IaaS provides automated and scalable environments that provide a high degree of control and flexibility for the user.
4. Platform as a Service (PaaS): A service provider offers access to a cloud-based environment in which users can develop, manage and deliver applications.
5. Software as a Service (SaaS): A service provider delivers software and applications through the internet or an API.
6. There are three basic types of deployment of cloud computing that are Public, Private and Hybrid.
7. In public cloud, all the services and supporting infrastructure are managed off-site over the internet and shared across multiple users.
8. Private cloud provides l.T services through the internet or a private network to selected users rather than to general public.
9. Hybrid cloud environments combine both Public and Private cloud elements.
