2. New Demand for IT infrastructure
 Capacity
 Massive processing power
 Massive Storage
 Security
 Availability
 Scalability
 Start small and grow on demand
 Cost effective

3. New Challenges
 High operating cost
 Man power cost
 Equipment cost
 Energy cost
 High operating complexity
 Changing technology
 Increase complexity
 Network, server, storage , security

4. Dream machine
 Computer with infinite capacity
 Start small and grow big based
on my demand
 Capacity can scale up and down
on demand
 Pay only what we use.
 No complex operating and
maintenance

5. It is called cloud computing system

6. What is Clouding Computing?
• A style of computing in
Cloud which dynamically scalable
and often virtualized
computing resources are provided as a
service over the Internet.

7. 4 Essential Utilities and
Delivery Networks
Water
(1) Water Distribution
Network
(2) Electricity
Power Grid
(3) Gas
Telecom
(4) Telephone Networks

8. Power Grid Inspiration for Computing?: Deliver ICT services
as “computing utilities” to users

10. Why we should move to the cloud?
 Quick start up
 no need to purchase any equipment. Subscribe, pay, and use it.
 Scalability
 less demand less computing power, more demand more
computing power
 Elasticity
 Handle the demand surge
 Less maintenance
 No need to hire people to fix server broken, hacking, tuning
 Less operation cost
 Pay only what you really use
 Cut the cost of maintaining huge infrastructure
 It is cool, trendy
 Just a stupid execute when people do not believe you ^_^

11. Three Cloud Service Models

12. Making it easier
Cloud Middleware and Management Software

13. Using IaaS Cloud
 User view the cloud as a number of servers
 Look the same as co-location server
 This is actually a virtual server
 Windows or many flavor of Linux
 User can start stop and reboot from web interface
 Normal web based application work fine
 Usage is charge on pay per use
 Can try at aws.amazon.com
 Open a new account and start a new server use less than 30
minutes to apply

14. Using PaaS Cloud
 PaaS cloud give you an API to program on the cloud
 There is a need to port application etc.
 .NET to Windows Azure
 Python to google app engine
 Pros and Cons
 More light weight that IaaS but need some application
porting effort

15. Cloud Application Development
UI Tier
Web2.0
Processing Data
Tier Management Tier
 Separate processing logic , UI, and DM Tier
 Using Services Oriented Architecture (SOA) design

16. Using SaaS Cloud
 You have already used it!
 Facebook
 Gmail
 Calendar
 Google Map
 Running application directly from you browser
 No coding , no porting just pay and use or use it for
free

17. What the Cloud can do?
 server consolidation
 Iaas cloud is the same as allow you to use many servers
hosted by service providers
 Scalable web application
 Community web like sanook , kapook
 Web app for anything you want to do
 Back end for mobile app
 iCloud, GoogleCloud are being used

18. The Cloud and I
Money Video
Data
Music books
Computing Power
Personal information
Services Picture
Application Games
ACCESS
ANYTIME STORAGE
ANYWHERE Internet SHARING
ANYHOW
RELIABILITY
SECURITY
AVAILABILITY

19. The Cloud and I
 Google docs (Office)
 Spread Sheet
 Word processor
 Presentation
 Calendar
 Gmail

20. The Cloud and I
calendar picture music
My cloud (google, facebook,
dropbox, amazon)
document

21. Work Life with a Cloud
 Appointment (google calendar)
 My secretary take appointment , add to calendar
 I got to see it on every device quickly, so is she
 Device notify me
 Email (gmail)
 I can go to any computer/device with browser, my email
follow me there.
 I have no need to install mail client, maintain mail server

22. Work Life with a Cloud
 Document (google docs)
 I can create basic document, good spreadsheet, basic
presentation without installing any software
 I can down load document and edit it on my computer
 I can share my document with other on internet and edit it
together
 Storage (google drive, dropbox)
 Create presentation on notebook, drop in in dropbox
 Present from iPad, Smartphone
 Secure, no need to carry thumb drive
 Easily share file with other people making team work easy

24. Play Life with a Cloud
 Picture
 Using Instagram, photo, video I take instantly appear on
twitter and facebook and neatly catalog
 Picture can be shared, tag, comment among my 2000 friends
on facebook!
 If I want, they will know where I was. (Little dangerous)
 Communication
 My thought can be spread anytime anyway using facebook,
googleplus, multiply
 I can even “hang out” with friend on google plus

25. Play Life with a Cloud
 Book
 Amazon Kindle Store. Buy book from amazon and they
will keep it on their cloud
 Unlimited book shelves, no cleaning, dusting
 Read your book on any device iPad, iPhone, Androiod
Phone, Tablet, PC, Mac
 I read mine on iPad, and my Galaxy S2 phone

26. Play Life with a Cloud
 Music
 iTune Store allow you to shopping for music, movies
 You can load it and play on many of your devices
 Media Industry is changing, now you can own a radio
station and TV station and get audiences around the
world
 Power shift from infrastructure provider (TV station) to
content creator ( like grammy etc.)

27. Moving KU Computer Engineering on
the Cloud
 Introduction
 Department of Computer Engineering is one of the leading
computer engineering in Thailand (23 years)
 Research and Education
 30 faculty member
 20-30 Ph.D students 50 Master, 120 MSIT, 400 Undergrad
 Mission
 Must support the teaching and research by providing server /
network/ service infrastructure
 Driving toward mobile anytime anywhere infrastructure

28. Moving KU Computer Engineering on
the Cloud
 Challenge and Opportunity
 Must provide a scalable and reliable infrastructure
 Servers, Storage
 Services
 Previously, a number of physical server has been used
 Getting old quickly, hard to maintain, a lot of space
 Consume a lot of power, cooling

29. Moving KU Computer Engineering on
the Cloud
 Cloud is Solution
 For Server, use VM cloud (VMware) to consolidate all small
server into a set of VM on only 5 machines
 Every lab, professor can request for VM for their use
 Can scale easily using more physical server
 Moving to centralize large storage using NAS/SAN storage
cloud

30. Direction
E- Video Virtual Virtual
Storage HPC
learning Server Desktop Server
Virtualized Cloud Infrastructure
Physical Infrastructure ( Srver, Storage, Network)

31. Cloud computing open issues
 People do not trust other to have their important
data
 And why people trust your bank to have all their
money?
 People do not trust that cloud provider can
provide a robust and secure environment
 How many time your system went down or being
hacked compared to google or facebook?
 Do avrage company have better staff than ISP
who deal with these problems on a daily basis
 Interesting!

32. Conclusion
 Cloud Computing is here!
 You are using it everyday
 SaaS Level such as facebook, gmail
 Let fly above the cloud and see what
it can do for you.

33. Thank you
