Cloud Computing

Cloud Computing provides a new computing model for networked applications.

This topic provides an understanding of the cloud computing model, including the operational architecture, system designs, advantages, and disadvantages. Cloud computing includes a range of computing resources (e.g., networks, servers, storage, applications, and services) that are available to users on-demand over a network with a shared pool of configurable resources that can be rapidly provisioned and released with minimal management effort or service provider interaction. This tutorial covers the factors involved in selecting applications for deployment under the cloud computing model.
