1. Im Cloud Confused Demystifying Cloud Computing

2. What the say:Biggest Paradigm Shift in 20 years Game Changers Just On Pay As You Go Tremendous Cost Cutting

3. Describe The Cloud To Me The Cloud 21 experts are defining cloud computing http://bit.ly/C6jIm*Picture taken under Creative Common license

4. Who Cares?What is it for me?

5. First, What the heck is Cloud ComputingFirst, what the heck isCloud Computing?in simple, plain English please!

6. Lets use a simple analogy Say you just moved to a city, and youre looking for a place to live

7. You can eitherBuild a house orRent an apartment

8. If you build a house, there are a fewimportant decisions you have tomake

9. How big is the house?are you planning to grow a large family?Remodel, addition typically cost a lotmore once the house is built

10. But, you get a chance to customize it flooring tile windows Roof floor planlighting landscaping

11. Once the house is built,youre responsible for maintenance Pay property taxHire Landscaper Water Plumber Electrician Electricity Heating and Cooling Gutter Cleaning House Keeping

12. How about renting ?

13. Consider a builder in your city buildsa massive number of apartment units

14. A unit can easily be convertedinto a 2,3,4 or more units

15. You make a fewer,simplerdecisionsYou can start with oneunit and grow later, ordownsize

16. ButYou do not have a lot of options tocustomize your unit

17. triple pane windows green materials high capacity electricity high speed InternetHowever, builders provide you withvery high quality infrastructure

18. No need to worry about maintenance cost No need to Hire landscapers, electricians, plumbers

19. Pay as You Go Just pay your rent and utilities

20. Lets translate toCloud Computing?

21. As an end-consumer, believe it or notyouve been using Cloud for long times

22. Yes, most of them areFree

23. In return, youre willing to give away your information for ads and other purposes

24. But youve been enjoying High Reliability Service (ok, ok, most of them are) Unlimited Storage Connecting, Sharing

25. OK, Now tell that to the business owner Give up your data, then you can use this infrastructure for free

26. This is how their CEO would feel

27. My Business NeedsSecurity Privacy Reliability High Availability

28. Building EnterpriseSoftware is like.Building MedievalCastle Stone Wall Fire-proof Moat Army Death Hole

29. Lets Hire an Army of IT Engineers Software Upgrade Support Backup/RestoreService Pack Development Network issues

30. Lets Build Huge Data Center Capacity PlanningCooling Management Disaster Plan Server Crashes

31. In the mean time, Many things have changed

32. The enterprise world we live in 2010 and beyond Global Direct, Open Customers(Customers, Resources, IPs are acquired everywhere) Communication (e.g. Social Media) Digital Life Convergence (Work and Personal lines are blurring) Work Remotely (Mobility Trend) Transparency (Blogs, Social Computing) Brief Collaboration (Assemble the best, Disassemble upon completion)

33. 2008-09Economy is upside down Layoffs Bankruptcy Excess Capacity

34. Can we bridge the gap?

35. Requiresa New Wayof Thinking

36. Cloud Computing is not the answer for all

37. But it could simplify our lives.

38. Leave it the experts who have a lot of money to spend to build giant datacenters across the globe

39. Your data is replicated3 or 4 times in their data center High Availability

40. High Traffic? Adding servers is a click away. Running in just minutes, not days

41. It can even load balance your server traffic

42. Expect your Cloud Network is always up

43. Yes, you can even pick where your data and servers reside

44. Business Contraction? Just reduce your computing power, storage

45. Wait,What is the catch?

46. Cloud Computing is relatively new technology

47. Growing Pains We all learn from it

48. Only a handful of major players can build this massive infrastructure

49. Not many software written yet to takeadvantage of cloud infrastructure

50. Sensitive Data in the Cloud? are there yet?Encryption Data at Rest Data in Motion

51. Yes, youre loosing some controls some configurations physical security only subset of APIs

52. Lets clear common confusions about Cloud Computing

53. Who is paying whom?

54. Typical Scenarios Software/Service Providers Cloud/Infrastructure Provider You You may also build software directly on the providers platform and(Business, Individual) pay them directly

55. Do I have to start over?

56. In some cases,you could redirect your data to the cloud Before Migrate Data to the Cloud

57. In some cases,you could redirect your data to the cloud After

58. However, to take advantage fully,migrate all or create new apps on the cloud Employees Suppliers Customers

59. Is this just Hosting 2.0?

60. No, they have different architectures and business model Cloud Players Hosting Players Hundreds of them around the worldOnly few can afford billions dollar investment on data centers

61. Your contracts Cloud Players Hosting PlayersPay As You Go Often yearlyPay only what you use

62. Reliability, High Availability,Capacity Elasticity Cloud Players Hosting PlayersVirtually unlimited Bring your own or rentstorage, computing power servers to increase capacity You have to manage Built-in Redundancy reliability, fail over yourself

63. The end of PC ?

64. NO Most cloud applications that will be built are accessible from PC. Applications can be a browser base, application running on PC accessing data and services on the cloud So will the mobile applications
