The document explains cloud computing using an analogy of renting an apartment instead of building a house, highlighting the advantages of flexibility, maintenance simplicity, and cost efficiency. It discusses the transition of businesses and individuals to cloud services, emphasizing high reliability and scalability while addressing concerns over security and data control. Cloud computing is presented as a response to the changing enterprise landscape, though it faces growing pains and potential confusion for users.

1. I’m CloudConfusedDemystifying 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 MeThe Cloud21 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 isCloud ComputingFirst, what the heck is Cloud Computing?…in simple, plain English please!

6. Let’s use a simple analogy Say you just moved to a city, and you’re looking for a place to live

7. You can eitherBuilda house or Rentan apartment

8. If you builda house, there are a fewimportant decisions you have to make…

9. Howbigis the house? are you planning to grow a large family? Remodel, addition typically cost a lot more once the house is built

10. But, you get a chance to customizeitflooringtilewindowsfloor planRooflightinglandscaping

11. Once the house is built, you’re responsible for maintenance Pay property taxHire LandscaperWaterElectricianElectricityPlumberHeating and Cooling Gutter CleaningHouse Keeping

12. How about renting?

13. Consider a builder in your city builds a massivenumber of apartment units

14. A unit can easilybe converted into a 2,3,4 or more units

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

16. But…You do nothavea lot of options to customize your unit

17. triple pane windowsgreen materialshigh capacity electricityhigh speed InternetHowever, builders provide you with very high quality infrastructure

18. No need to worryabout maintenance costNo need to Hirelandscapers, electricians, plumbers

19. Pay as You GoJust pay your rentand utilities

20. Let’s translate to Cloud Computing?

21. As an end-consumer, believe it or not you’ve been using Cloudfor long times

22. Yes, most of them are Free

23. In return, you’re willing to give awayyour informationfor ads and other purposes

24. But you’ve been enjoying High Reliability Service(ok, ok, most of them are)Unlimited StorageConnecting, Sharing

25. OK, Now tell that to the business ownerGive up your data, thenyou can use this infrastructure for free

26. This is how their CEO would feel

27. My Business Needs…SecurityPrivacyReliabilityHigh Availability

28. Building EnterpriseSoftwareis like…. Building Medieval CastleStone WallFire-proofMoatArmyDeath Hole

29. Let’s Hire an Army of IT EngineersSupportSoftware UpgradeBackup/RestoreService PackDevelopmentNetwork issues

30. Let’s BuildHuge Data CenterCapacity PlanningCooling Management Disaster PlanServer Crashes

31. In the mean time,… Many things have changed

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

33. 2008-09Economy is upside downLayoffsBankruptcy Excess Capacity

34. Can we bridge the gap?

35. Requires aNew WayofThinking

36. Cloud Computing is notanswerthefor all

37. But it could simplifyour lives….

38. Leave it the expertswho have a lot of money to spend to build giantdatacenters across the globe

39. Your data is replicated3 or 4 times in their data centerHigh 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 CloudNetworkis always up

43. Yes, you can even pick whereyour data and “servers” reside

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

45. Wait, What is the catch?

46. Cloud Computing is relatively newtechnology

47. Growing PainsWe all learn from it

48. Only a handful of major playerscan build this massive infrastructure

49. Not many software written yet to takeadvantage of cloudinfrastructure

50. Sensitive Data in the Cloud?are there yet? EncryptionData at RestData in Motion

51. Yes, you’re loosing some controls some configurationsphysical securityonly subset of APIs

52. Let’s clear common confusionsabout Cloud Computing

53. Who is paying whom?

54. Typical ScenariosSoftware/ServiceProvidersCloud/InfrastructureProviderYou(Business, Individual)You may also build softwaredirectly on the provider’s platform andpay them directly

55. Do I have to start over?

56. In some cases, you could redirectyour data to the cloud BeforeMigrate Data to the Cloud

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

58. However, to take advantage fully, migrate all or create new apps on the cloudEmployeesSuppliersCustomers

59. Is this just Hosting 2.0?

60. No, they have different architecturesand business modelCloud PlayersHosting PlayersHundreds of them aroundthe worldOnly few can afford billions dollar investment on data centers

61. Your contractsCloud PlayersHosting PlayersPay As You GoOften yearlyPay only what you use

62. Reliability, High Availability, Capacity ElasticityCloud PlayersHosting PlayersBring your own or rentservers to increase capacityVirtually unlimited storage, computing powerYou have to manage reliability, fail over yourselfBuilt-in Redundancy

63. The end of PC ?

64. NOMost cloud applications that will be built are accessible from PC. Applications can be a browser base, applicationrunning on PC accessing data and services on the cloudSo will the mobile applications
