What is Cloud?
Cloud computing has created a paradigm shift and become influential in today’s IT community. Increasingly business organizations are utilizing cloud as a new platform for many business operations. Cloud has been described from a number of different perspectives.
“Cloud computing is a model for enabling ubiquitous, convenient, on-demand network access to a shared pool of configurable computing resources (e.g. networks, servers, storage, applications and services) that can be rapidly provisioned and released with minimal management effort or service provider interaction.”
The cloud model is comprised of five essential characteristics: on-demand self-service, broad network access, resource pooling, rapid elasticity, and measured service. It includes three service models: Software as a Service, Platform as a Service, and Infrastructure as a Service. And it has four deployment models: Private, Public, Community, and Hybrid.
