Cloud Computing Elearning

1. Seventh International Conference on eLearning for Knowledge-Based
Society
Cloud Computing-The Magical
New ICT-Paradigm for Academic
xLearning ?
(eLearning, mLearning, uLearning)

2. Cloud Computing At A Glance
The term - Cloud
Computing – relatively new
The concept is not – Hotmail Web Hosting (Katzan 2010)
Lots of definitions (Golden 2009, Dothang 2010), the simplest one:
Cloud Computing – is getting computer services / resources
from the Internet.
Computer services means using all kinds of computer
resources on the web instead of using local resources.

3. Other Definitions of Cloud Computing
(Truitt 2009)
SaaS - Software-as-a-Service
SaaS - Security-as-a-Service
PaaS - Platform-as-a-Service
IaaS - Infrastructure-as-a-Service
XaaS – Everything-as-a-Service

4. Motivation
•
Merrill Lynch: 2012, the annual global market for cloud
computing is expected surge to $160 billion by 2012.
•
CA Technologies Chairman and CEO, William E. McCracken
said in CA World 2010 (May 2010): "In recent months, many
ask me whether I think that cloud computing is the IT future.
I always reply that I don't think, I'm sure".
•
Marc Andreessen, founder of the Mosaic web browser and
co-founder of Netscape, “cloud computing is the story of
the lifetime.”
•
Google CEO Eric Schmidt notes, "The cloud is a smart,
complex, powerful computing system in the sky that people
can just plug into."

5. Cloud Computing – Buzzword ?
Cloud Computing – is not a buzzword anymore !!!

11. Service Models
2 Main Models :
The First - Free Of Charge.
Implications: commercials, NO SLA (support, service,
backup, data security etc) Gmail and Facebook.
The Second – You Have To Pay.
The user can choose the SLA

12. Cloud Computing - types
 Private Cloud
 Public Cloud
 Community Cloud (shared library software)
 Hybrid Cloud – most common in the future

13. Trends in ICT that make Cloud
Computing Popular
 Economic crisis
 More bandwidth (remember the 14,400 modem vs. NGN)
 Here and now – 24 hours a day 7 days a week
from everywhere (during flights)
 Pressure to lower the IT cost – TCO
 Technology people are expensive
 Green IT
 Pay-Per-Use (rent instead of buy)
 Real need for Scalability

14. Trends In ICT 2
 Lower the risk of IT projects (less than 50%
of the ICT projects are considered successful)
 Downsizing of client side – the mobile phone /
SmartPhone
 Economies of scale
 Phobia among CIOs (open source, cloud)
 Implementation and assimilation

15. Trends In ICT 3
 Storage prices went down (large data centers)
 Storage requirements and reliability went up
 Advanced Technology – Grid Computing
 Virtualization Technology
 TCP/IP – became standard

16. Who Can Benefit ?

Large organizations – not the core activity,
quick results, less risk (50% failure). Share the Email
system 85% outside 15% inside

Small organizations – Email, website, open office (free !!!)
collaborate with others, data protection, FW, backup,
no maintenance, CRM for a penny (salesforce )

The Individual – Gmail, Facebook, Twitter
 In other words – every one !!!

17. Risks and Disadvantages
• Security issues in cloud commuting might not be
resolved completely
• Third party environment might be considered
unsafe for most organizations, (Jean Thilmany,
2010).
• Lack of privacy since the third party will have full
access to the data.

18. Risks
• Losing management control (infrastructure)
• Loss of control on the backup and maintenance activities
• Losing data protection management
• Dependence upon outer services
• Integration between local and Cloud Computing systems.
• Implementing Identity Management (IDM)
• Data interchange between applications (SOA)
• Risk management using Cloud Computing
is much more complicated.

20. Is Jeff Goldblum dead ?

21. Our Experience @ “COMAS”
The College of Management Academic Studies :
– founded in 1978
– Located 10 km south to Tel Aviv
– the first non-subsidized, academic institution in Israel
– the largest college in Israel
– over 12,000 students
– over 34,000 alumni
– 1,300 desktops (PCs) and 150 servers, 80 of them virtual

22. Cloud Systems @ COMAS
 CRM for community relations management
 CRM for donor relations management
 “Decision-follow-up" system
 Project portfolio management in the IT department
 Conferences registration system
 Synchronous eLearning Platform
 Picture Gallery (Picasa&WordPress) – New!

23. Business Simulation Game
ICT steering committee: slow and unreliable Internet connection

24. Synchronous eLearning Platform
®AT&T Connect

26. ®AT&T Connect
•A large technical infrastructure (IaaS)
is needed to deliver synchronous courses.
•Technical support for both students and
professors.

27. Which Service Should be Moved
to the Cloud
• (1) Is it the operation / system - a core
operationactivityprocessapplication?
• (2) Is there a comparative advantage to installing them
on local servers?
• (3) Is it much cheaper to get these applications over the
cloud?
• (4) Is timetable a factor? Is fast implementation needed?
• (5) What is the risk of data security and data protection?

28. Conclusions and Implications

The economic crisis

The pressure to lower ICT costs

Higher education institutions - budget problems (chalenges)

Lack of regulations (unlike banks)

29. Conclusions 2

COMAS: "Implementing the cloud computing solution was
quick,
cheap,
efficient,
and
effective
resulting
satisfaction rate among users."

 H.E. are highly motivated to move to the cloud

The main barrier is data protection and security.

Computer resources will eventually become commodities
high
