Seventh International Conference on eLearning for Knowledge-Based
Cloud Computing-The Magical
New ICT-Paradigm for Academic
(eLearning, mLearning, uLearning)
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.
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
Google CEO Eric Schmidt notes, "The cloud is a smart,
complex, powerful computing system in the sky that people
can just plug into."
Cloud Computing – Buzzword ?
Cloud Computing – is not a buzzword anymore !!!
Search of the term:
Number of search results:
Results @ Google
YouTube (xLearning) on Cloud Computing (one of many):
Cloud Computing – search ?
What are people looking for (popular google search):
Cloud Computing - Technology
Azure, .Net, sandbox,
Google, Java, php
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
Cloud Computing - types
Community Cloud (shared library software)
Hybrid Cloud – most common in the future
Trends in ICT that make Cloud
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
Pay-Per-Use (rent instead of buy)
Real need for Scalability
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 /
Economies of scale
Phobia among CIOs (open source, cloud)
Implementation and assimilation
Trends In ICT 3
Storage prices went down (large data centers)
Storage requirements and reliability went up
Advanced Technology – Grid Computing
TCP/IP – became standard
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 !!!
Risks and Disadvantages
• Security issues in cloud commuting might not be
• Third party environment might be considered
unsafe for most organizations, (Jean Thilmany,
• Lack of privacy since the third party will have full
access to the data.
• 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.
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
Cloud Systems @ COMAS
CRM for community relations management
CRM for donor relations management
Project portfolio management in the IT department
Conferences registration system
Synchronous eLearning Platform
Picture Gallery (Picasa&WordPress) – New!
Business Simulation Game
ICT steering committee: slow and unreliable Internet connection
•A large technical infrastructure (IaaS)
is needed to deliver synchronous courses.
•Technical support for both students and
Which Service Should be Moved
to the Cloud
• (1) Is it the operation / system - a core
• (2) Is there a comparative advantage to installing them
on local servers?
• (3) Is it much cheaper to get these applications over the
• (4) Is timetable a factor? Is fast implementation needed?
• (5) What is the risk of data security and data protection?
Conclusions and Implications
The economic crisis
The pressure to lower ICT costs
Higher education institutions - budget problems (chalenges)
Lack of regulations (unlike banks)
COMAS: "Implementing the cloud computing solution was
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
