This document provides an overview of cloud computing including definitions, characteristics, service models, deployment models, and security considerations. Cloud computing is defined as on-demand access to configurable computing resources that can be provisioned with minimal effort. Key characteristics include scalability, pay-per-use model, and enabling mobile applications. The three service models are Software as a Service (SaaS), Platform as a Service (PaaS), and Infrastructure as a Service (IaaS). The four deployment models are private, community, public, and hybrid clouds. General security challenges include trusting vendors and loss of physical control, while advantages were not outlined.

3. What is Cloud Computing?Slide 3Cloud computing is a model for enabling convenient, on-demand network access to a shared pool of configurable computing resources that can be rapidly provisioned and released with minimal management effort or service provider interaction.

4. Five Essential Cloud CharacteristicsSlide 4Allows business units to get the computing resources they need without having to go through IT for equipment.Enables applications to be built in ways that align with how businesses operate today - mobile, multi-device, etc.Allows for pooling of computing resources to serve multiple consumers. Allows for quick scalability or downsizing of resources depending on demand.Business units only pay for the computational resources they use.
