Cloud computing allows users to access computing resources like data storage and software applications over the internet instead of installing them locally. It provides benefits like flexibility, scalability, and reduced costs compared to maintaining physical computing infrastructure. However, moving to the cloud also means giving up some control and configuration options. While cloud computing is not a solution for all businesses, it can simplify IT management for many by letting experts handle maintenance of huge data centers instead of businesses running their own physical servers.

1. I’m CloudConfused 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 Computing First, 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 either Builda house or Rentan apartment

8. If you builda house, there are a few important 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 customizeit flooring tile windows floor plan Roof lighting landscaping

11. Once the house is built, you’re responsible for maintenance Pay property tax Hire Landscaper Water Electrician Electricity Plumber Heating and Cooling Gutter Cleaning House 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, simpler decisions You can start with one unit and grow later, or downsize

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

17. triple pane windows green materials high capacity electricity high speed Internet However, builders provide you with very high quality infrastructure

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

19. Pay as You Go Just pay your rent and 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. In return, you’re willing to give away your informationfor ads and other purposes

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

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

25. This is how their CEO would feel

26. My Business Needs… Security Privacy Reliability High Availability

27. Building Enterprise Software is like…. Building Medieval Castle Stone Wall Fire-proof Moat Army Death Hole

28. Let’s Hire an Army of IT Engineers Support Software Upgrade Backup/Restore Service Pack Development Network issues

29. Let’s Build Huge Data Center Capacity Planning Cooling Management Disaster Plan Server Crashes

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

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

32. 2008-09 Economy is upside down Layoffs Bankruptcy Excess Capacity

33. Can we bridge the gap?

34. Requires aNew Way ofThinking

35. Cloud Computing is not answer the for all

36. But it could simplifyour lives….

37. Leave it the experts who have a lot of money to spend to build giantdatacenters across the globe

38. Your data is replicated 3 or 4 times in their data center High Availability

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

40. It can even load balance your server traffic

41. Expect your Cloud Network is always up

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

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

44. Wait, What is the catch?

45. Cloud Computing is relatively newtechnology

46. Growing Pains We all learn from it

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

48. Not many software written yet to takeadvantage of cloudinfrastructure

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

50. Yes, you’re loosing some controls some configurations physical security only subset of APIs

51. Let’s clear common confusions about Cloud Computing

52. Who is paying whom?

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

54. Do I have to start over?

55. In some cases, you could redirectyour data to the cloud Before Migrate Data to the Cloud

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

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

58. Is this just Hosting 2.0?

59. No, they have different architecturesand business model Cloud Players Hosting Players Hundreds of them around the world Only few can afford billions dollar investment on data centers

60. Your contracts Cloud Players Hosting Players Pay As You Go Often yearly Pay only what you use

61. Reliability, High Availability, Capacity Elasticity Cloud Players Hosting Players Bring your own or rent servers to increase capacity Virtually unlimited storage, computing power You have to manage Reliability, fail over yourself Built-in Redundancy

62. The end of PC ?

63. 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
