==Cloud computing applications in different industry segments==
===Hospitality===
Cloud computing is used in hospitality industry to provide
* Disaster recover infrastructure for mission critical applications
* For online reservation system
* Purchase of a dedicated pool of computing resources and allocating them as needed
* Facilitating in responding to real-time situations
:e.g. Preferred Hotel Group is using Terremark's Enterprise cloud services

===Web applications===
Cloud computing is used in various web applications such as Microsoft's Hotmail, Google's Gmail and YouTube, and Yahoo's Flickr photo-sharing service etc<BR>
* Consumers run only their browsers on local computers
* The rest of the software along with users' email messages, photos or videos are on remote machines the user can't see and doesn't have to know anything about it
:e.g. Microsoft's Hotmail is using Azure (cloud computing platform from Microsoft) and Google's Gmail is using Google Apps
* Google Docs - online versions of word processor and spreadsheet applications is also using cloud computing

===Consumer electronics===
Cloud computing is being used in consumer electronics at various levels:
* In Laptop computers for Wireless communication and access to the Internet
* Laptops require minimum hardware to reduce cost and a internet connection
* Gaming industry, that will allow iPhones and other thin-client devices to have really high-end graphics without having a big, expensive hot video card in them that draws battery life
:e.g Netbook, a general purpose laptop, works on cloud computing and is available at a price of US$400 and some even in US$50-100 range.

===Telecommunication===
* Enterprises use various operating systems to create virtual private data centers for business lines or applications
* A virtual private data center is functionally equivalent to a co-location facility
* It allow users to define custom application infrastructures using just a browser
* Operating system then creates and maintains the infrastructure for the user on the grid
* It simplify data center design and operations and helping enterprises meet requirements such as high availability and disaster recovery
:e.g. British Telecom is using AppLogic, product of 3Tera, for utility computing services
