    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

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. Lets use a simple analogy
Say you just moved to a city, and youre 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

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. Lets translate to
Cloud Computing?
21. As an end-consumer, believe it or not
youve been using Cloudfor long times
22. In return, youre willing to give away
your informationfor ads and other purposes
23. But youve 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. Lets Hire an Army of IT Engineers
Support
Software Upgrade
Backup/Restore
Service Pack
Development
Network issues
29. Lets 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, youre loosing some controls
some configurations
physical security
only subset of APIs
51. Lets 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 providers 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 differentarchitecturesand 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
