Wikipedia Cloud computing is Internet-based computing, whereby shared resources, software and information are provided to computers and other devices on-demand, like a public utility. Gartner Style of computing in which scalable and elastic IT-enabled capabilities are delivered as a service to external customers using Internet technologies Forrester Standardized IT capability (services, software, or infrastructure) delivered via Internet technologies in a pay- per-use, self-service way.
Cloud computing is a model for enabling Ubiquitous, Convenient, On-demand network access to a shared pool of configurable computing resources Networks Servers Storage that can be rapidly provisioned and released with minimal management effort or service provider interaction.

Broad Network Access Rapid Elasticity Measured Service On-Demand Self- Service Resource Pooling
Ubiquitous network access means that the cloud providers capabilities are available over the network and can be accessed through standard mechanisms by both thick and thin clients.
Elasticity is defined as the ability to scale resources both up and down as needed. To the consumer, the cloud appears to be infinite, and the consumer can purchase as much or as little computing power as they need.

Public Private Community Hybrid IaaS PaaS SaaS What is Service Models?
Core Computing Resources Servers Storage Network IaaS - Infrastructure as a Service Infrastructure Management is abstracted from users Elastic and On-Demand Pay per use
20 servers daytime during peak load, but only need 2 during normal load 100 servers for 48 hours to do some load testing 10 TB of storage to backup my data Infrastructure to implement my disaster recovery mechanism
Over a period of time Amazon has built A massively scalable & distributed system Scale capacity on demand Reliable infrastructure Amazon has made this infrastructure available to public Known as AWS (Amazon Web Service)

Software Application Servers Messaging Notification Services PaaS - Platform as a Service Platform for deployment and management of business applications Management of infrastructure is abstracted Load balancing, clustering, database management are also abstracted from users Scales up or down automatically on demand
Deploy web application on an infrastructure that can scale as demand grows LAMP Stack Ruby on Rails Springs Deploy Microsoft applications No management overhead Platform maintenance and operations Database backup & Disaster Recovery Scalability & Fault tolerance
Applications HR CRM Financial, Sales Automation, ERP etc SaaS - Software as a Service Application implementation, management & configuration is abstracted Disaster recovery, failover are taken care of behind the scene Should provide integration capability to enterprise systems Pay per users and functionalities availed or resources used like storage etc
