Cloud Computing Cloud computing refers to the delivery of computing and storage capacity as a service to a heterogeneous community of end-recipients. Cloud computing entrusts services with a user's data, software and computation over a network. It has considerable overlap with software as a service (SaaS).

F.A.Q. Is the cloud just a fad? No. It’s a rational evolution of IT architecture towards a more efficient way of managing resources and designing Web apps efficiently. Is the cloud cheap? No. The cloud allows you to pay the right for each service involved. Is the cloud just a scalable vps? No. The cloud is a set of services designed to meet specific computing needs.

…as a Service SaaS Software as a service is a software delivery model in which software and associated data are centrally hosted on the cloud. IaaS In the most basic cloud-service model, providers of Ifrastructure as a Service offer computers - physical or (more often) virtual machines - and other resources. PaaS In the Platform as a Service model, cloud providers deliver a computing platform typically including operating system, programming language execution environment, db, and web server. DaaS Data as a Service brings the notion that data quality can happen in a centralized place
