This document discusses cloud computing and compares it to traditional IT outsourcing and managed services. Cloud computing allows users to access software, servers, and storage over the internet instead of having to buy, install, and manage their own resources. The document outlines the service models of infrastructure as a service (IaaS), platform as a service (PaaS), and software as a service (SaaS). It then presents a scenario where a company needs to quickly launch a new product worldwide and argues that cloud computing would allow them to do this more quickly and cost-effectively than relying on their in-house IT department.
2. Cloud computing is a computing model that lets you access software, server and storage resources over the Internet, in a self-service manner. Instead of having to buy, install, maintain and manage these resources on your own computer or device, you access and use them through a Web browser. Cloud computing is a general term for anything that involves delivering hosted services over the Internet.
