Cloud Computing At A GlanceCloud 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.

MotivationMotivation• 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."

Service ModelsService 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

Trends in ICT that make Cloud Trends in ICT that make Cloud Computing PopularComputing 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
![Page 14: Seventh International Conference on eLearning for Knowledge-Based Society Cloud Computing-The Magical New ICT-Paradigm for Academic xLearning ? (eLearning,](https://reader033.vdocuments.mx/reader033/viewer/2022061306/55147c92550346f06e8b4748/html5/thumbnails/14.jpg)
Trends In ICT 2 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

Trends In ICT 3 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

Who Can Benefit ?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 DisadvantagesRisks 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.
![Page 18: Seventh International Conference on eLearning for Knowledge-Based Society Cloud Computing-The Magical New ICT-Paradigm for Academic xLearning ? (eLearning,](https://reader033.vdocuments.mx/reader033/viewer/2022061306/55147c92550346f06e8b4748/html5/thumbnails/18.jpg)
RisksRisks
• 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.

Which Service Should be Moved Which Service Should be Moved to the Cloud to the Cloud
• (1) Is it the operation / system - a core operation\
activity\process\application?
• (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?

Conclusions and ImplicationsConclusions and Implications
The economic crisis
The pressure to lower ICT costs
Higher education institutions - budget problems (chalenges)
Lack of regulations (unlike banks)
![Page 29: Seventh International Conference on eLearning for Knowledge-Based Society Cloud Computing-The Magical New ICT-Paradigm for Academic xLearning ? (eLearning,](https://reader033.vdocuments.mx/reader033/viewer/2022061306/55147c92550346f06e8b4748/html5/thumbnails/29.jpg)
Conclusions 2 Conclusions 2
COMAS: "Implementing the cloud computing solution was
quick, cheap, efficient, and effective resulting high
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
