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.

Other Definitions of Cloud Other Definitions of Cloud ComputingComputing(Truitt 2009)(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

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."

Cloud Computing – Buzzword ?Cloud Computing – Buzzword ?

Cloud Computing – is not a buzzword anymore !!!

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

Cloud Computing - typesCloud Computing - types

Private Cloud

Public Cloud

Community Cloud (shared library software)

Hybrid Cloud – most common in the future

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

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.

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.

Our Experience @ “COMAS”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

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)

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
