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.
Cloud confused
- 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 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 customizeitflooringtilewindowsfloor planRooflightinglandscaping
- 11. Once the house is built, you’re responsible for maintenance Pay property taxHire LandscaperWaterElectricianElectricityPlumberHeating and Cooling Gutter CleaningHouse Keeping
- 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. In return, you’re willing to give awayyour informationfor ads and other purposes
- 23. But you’ve been enjoying High Reliability Service(ok, ok, most of them are)Unlimited StorageConnecting, Sharing
- 24. OK, Now tell that to the business ownerGive up your data, thenyou can use this infrastructure for free
- 25. This is how their CEO would feel
- 26. My Business Needs…SecurityPrivacyReliabilityHigh Availability
- 27. Building EnterpriseSoftwareis like…. Building Medieval CastleStone WallFire-proofMoatArmyDeath Hole
- 28. Let’s Hire an Army of IT EngineersSupportSoftware UpgradeBackup/RestoreService PackDevelopmentNetwork issues
- 29. Let’s BuildHuge Data CenterCapacity PlanningCooling Management Disaster PlanServer Crashes
- 30. In the mean time,… Many things have changed
- 31. The enterprise world we live in 2010and beyondDirect, Open CustomersCommunicationGlobal (e.g. Social Media)(Customers, Resources, IPs are acquired everywhere)Digital Life Convergence(Work and Personal lines are blurring)Work Remotely(Mobility Trend)TransparencyBrief Collaboration(Blogs, Social Computing)(Assemble the best, Disassemble upon completion)
- 32. 2008-09Economy is upside downLayoffsBankruptcy Excess Capacity
- 33. Can we bridge the gap?
- 35. Cloud Computing is notanswerthefor all
- 36. But it could simplifyour lives….
- 37. Leave it the expertswho have a lot of money to spend to build giantdatacenters across the globe
- 38. Your data is replicated3 or 4 times in their data centerHigh 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 CloudNetworkis 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 PainsWe all learn from it
- 47. Only a handful of major playerscan build this massive infrastructure
- 48. Not many software written yet to takeadvantage of cloudinfrastructure
- 49. Sensitive Data in the Cloud?are there yet? EncryptionData at RestData in Motion
- 50. Yes, you’re loosing some controls some configurationsphysical securityonly subset of APIs
- 51. Let’s clear common confusionsabout Cloud Computing
- 52. Who is paying whom?
- 53. Typical ScenariosSoftware/ServiceProvidersCloud/InfrastructureProviderYou(Business, Individual)You may also build softwaredirectly on the provider’s platform andpay them directly
- 54. Do I have to start over?
- 55. In some cases, you could redirectyour data to the cloud BeforeMigrate 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 cloudEmployeesSuppliersCustomers
- 58. Is this just Hosting 2.0?
- 59. No, they have different architecturesand business modelCloud PlayersHosting PlayersHundreds of them aroundthe worldOnly few can afford billions dollar investment on data centers
- 60. Your contractsCloud PlayersHosting PlayersPay As You GoOften yearlyPay only what you use
- 61. 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
- 62. The end of PC ?
- 63. NOMost 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 cloudSo will the mobile applications
