This document discusses cloud operating systems. It begins with an introduction that describes how cloud computing allows software and documents to be stored on remote servers and accessed from any device rather than a personal computer. Examples of cloud OS are provided, such as Google Chrome OS. The document then defines a cloud OS as a browser-based OS that provides access to web apps without needing a full OS. Reasons for using a cloud OS include platform independence, centralized storage, and data sharing. The architecture of a cloud OS is explained as clients connecting to servers over the network. Applications and advantages/disadvantages of cloud OS are listed. The conclusion discusses how cloud OS provides supercomputing power across devices.

3. Introduction
 With traditional desktop computing, we run copies of software programs on our
own computer. The documents we create are stored on our own pc.
 Although documents can be accessed from other computers on the network, they
can’t be accessed by computers outside the network. This is PC-centric.
 With cloud computing, the software programs one use aren’t run from one’s
personal computer, but are rather stored on servers accessed via the Internet.

4.  If a computer crashes, the software is still available for others to use. Same goes for
the documents one create; they’re stored on a collection of servers accessed via the
Internet.
 Anyone with permission can not only access the documents, but can also edit and
collaborate on those documents in real time.
 Unlike traditional computing, this cloud computing model isn’t PC-centric, it’s
document-centric.

5. Examples of cloud operating systems
 EyeOS
 Joli OS
 Easy Peasy
 Google Chrome OS
 Osw3
 Own cloud

6. What is cloud operating System?
 Cloud operating system that runs just a web browser, providing access to a variety
of web-based applications that allow the user to perform many simple tasks
without booting a full-scale operating system. Because of its simplicity, Cloud
operating system can boot in just a few seconds.
 The operating system is designed for Netbooks, Mobile Internet Devices, and PCs
that are mainly used to browse the Internet.
 From Cloud the user can quickly boot into the main OS, because Cloud continues
booting the main OS in the background.
 Combining a browser with a basic operating system allows the use of cloud
computing, in which applications and data "live and run" on the Internet instead of
the hard drive.

7. Why cloud OS?
 For platform independence.
 Faster and safer access.
 Centralisized storage.
 Huge data analysis.
 Data sharing.
 Better administration.

9.  Individual users connect to the cloud from their own personal computers or
portable devices, over the Internet. To these individual users, the cloud is seen as a
single application, device, or document.
 The hardware in the cloud (and the operating system that manages the hardware
connections) is invisible.
 Data and instuctions are sent to cloud system. Here all data is stored.
 All insturctions passed over the network and information processed in the cloud
only.

10. Applications
 In company / organisation environment.
 For research and development.
 Social networking.
 Remote Assistance.
 Gamming.

11. Live Demonstration

12. Storage
 Data is centralisized so we can easily analyse,arrange and sharing over the
network.
 We can use access the data even the clent system file system is different.
 Can provide the better security to the data and also set restrictions to the users.
 Multiple users can access the same data many times.
 Common application format.

13. Advantages
 Lower computer costs.
 Improved performance.
 Reduced software costs.
 Instant software updates.
 Improved document format compatibility.
 Unlimited storage capacity.
 Increased data reliability.
 Universal document access.
 Latest version availability.
 Device independence.

14. Disadvantages
 Requires a constant Internet connection.
 Does not work well with low-speed connections.
 Features might be limited.
 Can be slow.
 Stored data might not be secure without proper administartion.
 Stored data can be lost by hardware failures.

15. Conclusion
 Thus cloud operating system provide a super-computing power .
 This cloud of computers extends beyond a single company or enterprise and also
home PC’s.
 The applications and data served by the cloud are available to broad group of
users, cross-enterprise and cross-platform.
 In future every home becomes a smart home by using the cloud service.
 A revoluation can’t stop by anyone.
