The document explains cloud computing using the analogy of renting an apartment versus building a house, emphasizing the lower maintenance and cost benefits associated with cloud services. It notes the complexities and considerations for businesses when using cloud technologies, as well as potential security and control concerns. Overall, it highlights cloud computing as a transformative but evolving solution that is not suitable for every scenario.

1. I’m 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

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
Build a house or
Rent an apartment

8. If you build a house, there are a few
important decisions you have to
make…

9. How big is 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 customize it
flooring
tile windows
Roof floor plan
lighting
landscaping

11. Once the house is built,
you’re responsible for maintenance
Pay property tax
Hire Landscaper
Water
Plumber Electrician Electricity
Heating and Cooling Gutter Cleaning
House Keeping

12. How about renting ?

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

14. A unit can easily be 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 not have
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 worry about maintenance cost
No need to Hire landscapers,
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 Cloud for long times

22. Yes, most of them are
Free

23. In return, you’re willing to give away
your information
for 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
Software Upgrade
Support
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
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. 2008-09
Economy is upside down
Layoffs Bankruptcy
Excess Capacity

34. Can we bridge the gap?

35. Requires
a New Way
of 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 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
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 take
advantage of cloud infrastructure

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

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

52. Let’s 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 provider’s 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 world
Only few can afford billions dollar
investment on data centers

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

62. Reliability, High Availability,
Capacity Elasticity
Cloud Players Hosting Players
Virtually unlimited Bring your own or rent
storage, 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
