  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 *Picture taken under Creative Common license

  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

  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 away your informationfor ads and other purposes

  24. But you’ve 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 Needs… Security Privacy Reliability High Availability

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

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

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

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

  32. The enterprise world we live in 2010and beyond Global 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) Transparency Brief Collaboration (Blogs, Social Computing) (Assemble the best, Disassemble upon completion)

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

  34. Can we bridgethe gap?

  35. Requires aNew Way ofThinking

  36. Cloud Computing is not answer the for all

  37. But it could simplifyour lives….

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

  39. Your data is replicated 3 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 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 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 cloudinfrastructure

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