3. 8/14/2010 3 OVERVIEW

5. In other words, this is a collection/group of integrated and networked hardware, software and Internet infrastructure.

6. Using the Internet for communication and transport provides hardware, software and networking services to clients.

7. These platforms hide the complexity and details of the underlying infrastructure from users and applications by providing very simple graphical interface or API (Applications Programming Interface).

8. Simply a metaphor for the internet8/14/2010 4

10. Cloud computing is an umbrella term used to refer to Internet based development and services.

11. Remotely hosted: Services or data are hosted on remote infrastructure.

13. General Magic launched a short-lived Cloud Computing product in 1995

14. Salesforce.com was established in 1999 which provided the concept of ‘On Demand’ & Saas6 8/14/2010

16. IBM detailed these concept in 2001

17. Amazon modernized their datacenters in 2005

18. In 2007 Google, IBM etc embarked on a large scale CC research project

20. Information is permanently stored in servers on the internet

21. Cachedtemporarilyon clients like desktops, hand-helds, sensors etc.

22. A style of computing

23. IT services and resources are provided as a service over the internet8 8/14/2010s

25. Once you login, the device is “yours”.

26. Data stored on remote servers in the “cloud” (with large capacity)9 8/14/2010

31. Multi- Tenancy

32. Reliability and Self Healing

33. Scalability

60. Portability/ Accessibility

61. Efficient Use of Computer Resources

63. By using the Cloud infrastructure on “pay as used and on demand”, all of us can save in capital and operational investment!

64. Clients can:

65. Put their data on the platform instead of on their own desktop PCs and/or on their own servers.

67. It enables services to be used without any understanding of their infrastructure.

68. Cloud computing works using economies of scale:

69. It potentially lowers the outlay expense for start up companies, as they would no longer need to buy their own software or servers.

70. Cost would be by on-demand pricing.

71. Vendors and Service providers claim costs by establishing an ongoing revenue stream.

73. Use of cloud computing means dependence on others and that could possibly limit flexibility and innovation:

74. The others are likely become the bigger Internet companies like Google and IBM, who may monopolise the market.

75. Some argue that this use of supercomputers is a return to the time of mainframe computing that the PC was a reaction against.

76. Security could prove to be a big issue:

77. It is still unclear how safe out-sourced data is and when using these services ownership of data is not always clear.

78. There are also issues relating to policy and access:

79. If your data is stored abroad whose FOI policy do you adhere to?

80. What happens if the remote server goes down?

81. How will you then access files?

84. You do not need a high-powered and high-priced computer to run cloud computing's web-based applications.

85. Since applications run in the cloud, not on the desktop PC, your desktop PC does not need the processing power or hard disk space demanded by traditional desktop software.

86. When you are using web-based applications, your PC can be less expensive, with a smaller hard disk, less memory, more efficient processor etc.

88. Another advantage to cloud computing is that you are no longer faced with choosing between obsolete software and high upgrade costs.

89. When the application is web-based, updates happen automatically - available the next time you log into the cloud.

90. When you access a web-based application, you get the latest version - without needing to pay for or download an upgrade.

91. Improved document format compatibility

92. You do not have to worry about the documents you create on your machine being compatible with other users' applications or operating systems.

93. Where Word 2007 documents cannot be opened on a computer running Word 2003, all documents can be read!

95. Cloud computing offers virtually limitless storage.

96. Your computer's current 200 Gbyte hard drive is small compared to the hundreds of Tbytes available in the cloud.

97. Whatever you need to store, you can & you can access it from anywhere in the world using internet connection..

98. Increased data reliability

99. Unlike desktop computing, in which if a hard disk crashes and destroy all your valuable data, a computer crashing in the cloud should not affect the storage of your data.

100. That also means that if your personal computer crashes, all your data is still out there in the cloud, still accessible.

102. Does not work well with low-speed connections

103. Similarly, a low-speed Internet connection, such as that found with dial-up services, makes cloud computing painful at best and often impossible.

104. Web-based applications require a lot of bandwidth to download, as do large documents.

105. If you are labouring with a low-speed dial-up connection, it might take seemingly forever just to change from page to page in a document.

107. Today many web-based applications simply are not as full-featured as their desktop-based applications.

108. For example, you can do a lot more with Microsoft PowerPoint than with Google Presentation's web-based offering.

109. The basics are similar, but the cloud application lacks many of PowerPoint's advanced features.

110. Stored data can be lost

111. Theoretically, data stored in the cloud is safe, replicated across multiple machines.

113. With cloud computing, all your data is stored on the cloud.

114. The questions is How secure is the cloud?

115. Can unauthorised users gain access to your confidential data?

116. Cloud computing companies say that data is secure, but it is too early to be completely sure of that.

118. All major IDEs will provide cloud deployment options

119. A next- generation of “Middleware for the cloud” will rise in dominance over traditional J2EE Application Servers

121. 8/14/2010 38 This was what the pioneers in the field concluded… Cloud computing is using the internet to access someone else's software running on someone else's hardware in someone else's data center. In this architecture, the data is mostly resident on servers ‘somewhere on the Internet’ and the application runs on both the ‘cloud servers’ and the user’s browser. Cloud computing is an emerging approach to shared infrastructure in which large pools of systems are linked together to provide IT services. Eric Schmidt Lewis Cunningham, Oracle Ace Director IBM press release on “Blue Cloud” It’s one of the foundations of the next generation of computing. . .. It’s a world where the network is the platform for all computing, where everything we think of as a computer today is just a device that connects to the big computer we’re building. Cloud computing is a great way to think about how we’ll deliver computing services in the future. We really don’t want to operate data centres anymore. We’d rather spend our time giving our customers great service and writing great software than managing physical hardware. Don MacAskill, CEO, SmugMug Tim O’Reilly, CEO, O’Reilly Media
