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.
Other Definitions of Cloud Computing (Truitt 2009) Saa. S - Software-as-a-Service Saa. S - Security-as-a-Service Paa. S - Platform-as-a-Service Iaa. S - Infrastructure-as-a-Service Xaa. S – Everything-as-a-Service
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. Mc. Cracken 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. "
Cloud Computing – Buzzword ? Cloud Computing – is not a buzzword anymore !!! Search of the term: http: //www. google. com/insights/search/ Number of search results: Results @ Google You. Tube (x. Learning) on Cloud Computing (one of many): http: //www. youtube. com/watch? v=QJnc. Firhj. Pg
Cloud Computing – search ? What are people looking for (popular google search):
Client/server Computing on the Internet
Cloud Computing - Technology System Layer Development Environment CPU OS Grid Computing Windows, Linux, IOS…. Virtualization Technology Development Azure, . Net, sandbox, Google, Java, php Storage Systems Data Base Proprietary Open Oracle, Postgres, Ms-SQL My. SQL Application Layer
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
Cloud Computing - types § Private Cloud § Public Cloud § Community Cloud (shared library software) § Hybrid Cloud – most common in the future
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
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 / Smart. 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 § Virtualization Technology § 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 resolved completely • Third party environment might be considered unsafe for most organizations, (Jean Thilmany, 2010). • Lack of privacy since third party will have full access to the data.
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.

Is Jeff Goldblum dead ?
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 § “Decision-follow-up" system § Project portfolio management in the IT department § Conferences registration system § Synchronous e. Learning Platform § Picture Gallery (Picasa&Word. Press) – New!
Business Simulation Game ICT steering committee: slow and unreliable Internet connection
Synchronous e. Learning Platform AT&T Connect®
AT&T Connect® • A large technical infrastructure (Iaa. S) is needed to deliver synchronous courses. • Technical support for both students and professors.
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?
Conclusions and Implications § The economic crisis § The pressure to lower ICT costs § Higher education institutions - budget problems (chalenges) § Lack of regulations (unlike banks)
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
