Cloud computing
Cloud computing latest major shift in ideas and applications related to information
technology services, especially with regard to infrastructure solutions that rely on institutions
to facilitate their operations, and found a lot of institutions, large and small enlist in this new
system and predicted a recent study for the Foundation IDC Global specialized in research
that Cloud computing provides additional revenue for the institutions of more than a trillion
.dollars by 2014
Definition

?

Technology is based on the transfer and processing of computer storage space to the
so­called cloud, a device server to be accessed via the Internet, and this turn of information
technology software products to services. Thus, this technology contributes to the problems
of clearing the maintenance and development of software for information technology
companies have used, and thus concentrated effort of the beneficiaries to use these services
only. And rely infrastructure cloud computing data centers that offer advanced and large
storage spaces for users as they provide some of the programs as a service to users, and relies
.on the capabilities provided by Web 2.0 technologies

:cloud computing model is based on the following basic classes
Providing software as a service (SAAS) :layer of cloud computing and more

interested in relating to end­user applications such as e­mail systems, customer
relationship management applications, common software and systems management

Provide software platforms as a service (PAAS) : a layer of cloud computing

consists mainly of libraries, programs and intermediates, and updates the runtime and
tools needed by developers in updating the software application as a service. The
benefit of the technology platform as a service layer in virtual environments
“infrastructure as a service” to deploy and provide software developed sources in
.virtual infrastructure as a service
The “infrastructure as a service”(IAAS): they provide the infrastructure for

computer, and instead of buying servers, software, data center space or a private
network equipment customers purchased these sources as a service completely
independent. The service description is usually on the basis of utility computing and
how the sources used and thus the cost, which will necessarily reflected on the level of
activity. The use of cloud computing technology of virtual computing (Virtualization
Technology) extensively in the model “infrastructure as a service” of their own as it
helps to provide energy, cost, and space in data centers, default is what is considered a
.cornerstone in the structure of the cloud
the beneficiaries of cloud computing

?

the small and medium enterprises more beneficiaries of this new technology, as well as
large companies because they will work the system the Out­ sourcing, which designed its
model of computing allows them to optimize the use of infrastructure, and to achieve the
desired objectives, and thus will be redundant then for creativity at work to be able to deal
.with new technology
Cloud computing is also an integral part of the industry, data centers and therefore the
information will help to rationalize the consumption of thermal energy related

emissions, where he became the main challenge for those in charge of accounting at
.the company’s resources on how to reduce the time
It is also cloud computing is one of the most prominent new phenomena in the world,

?

a way of innovative and intelligent to provide services and applications in a simple
and moving, it is also a panacea to counter the negative effects of the economic crisis
that plagued all countries and sectors since the beginning of 2009 and shows that clear
in cost savings Finance not inconsistent with the efficient functioning of the
applications and solutions, and at the level of software products, and hard­ware. It
also achieved significant savings of up to 70% which is the percentage allocated in
any company for the operating system, or the so­called Operation­System also
contribute to cloud computing to cut an estimated 40 to 60% of the budget of any
.company dedicated to the telecom sector and information technology
First, the positives

?

The main importance in the following points
Cost: low in terms of reducing the purchase price of the equipment, and change the

.A

license application system where service has been made on the basis of subscribing
.to it
Scalability and Availability: where have the services and the sites hosted on the

.B

cloud host provider to cloud the possibility of determining the scope at which
.demand is always available to users
No limits of computing and storage: there are no limits for storage and processing

.C

.on the cloud theory, but there are some obstacles in practice
Focus on the core business rather than IT: where business owners need to focus on

.D

their core mission rather than trying to address the management of information
.technology
Provide resources in a more dynamic: they provide users with the computing

.E

.resources they need at any time and in a dynamic way
More Efficient: It does not matter whereabouts of your equipment is the most
.important thing that operate well and that the service will be available

.F

IT­friendly environment (Green IT): cloud computing and virtual environment in

.G

general play an important role and effectively in the development of the movement
of “Green IT”, the technology is green and cloud computing were closely linked, as
the technology of cloud computing is the technology Virtual and works to reduce
the number of machinery and equipment used and thus reflected on green
.technology because it also helps in saving energy

Second: the negatives
And are summarized in the following points
Security: you information are important exist on the Internet, can be trusted storage?

.A

If the number of terrorists attacked a number of clouds computing what will be the
?fate of your business
Privacy and data ownership: Is your applications are not ready to deal with after the

.B

.cloud and need to be some adjustments to adapt to the cloud environment
To ensure the level of service: Is it provides this service is always? What about

.C

service level agreements? What about connecting to the network and site access
?servers and various services on the cloud
Joint work and integration of services between the clouds: Is there a possibility to

.D

move from a vendor service for another without having to change the texts and the
environment in which I work? Can not demonstrate compliance or revised after.
We will have a major effort to deploy applications on the cloud to conform with
the work of compliance, such as “H, but any AA, S or X (HIPAA, SOX etc.) …
.”Etc
There is also a cloud Gurmerih and extremely dangerous spread continuously and
steadily around the whole world, with the transfer of data storage digital with hard
drives on computers to a system of cloud computing and storage on the Internet
has increased the amount of waste digital wasted dramatically during the last
decade, and includes such wastes digital e­mails The photos and video clips and

.E

?

music that are stored on the Internet without a real need her, and without re­used
.again
The challenges

?

The challenges that hinder the spread of cloud computing including environment of
cloud involves many challenges and gaps several security can not be for security solutions
conventional face, as I mentioned earlier that security is the first concern of the challenges or
issues troubling when talking about cloud computing, but it has developed a “Otrend
Maekerob” package integrated security solutions and advanced Trend Micro Secure Cloud to
provide protection to remove such concerns as the challenge of this new package of security
risks, and concerns related to privacy and interoperability at the dissemination of information
in the cloud computing environment. Today, after taking determined parameters of cloud
computing, and companies began to store massive amounts of data in the institutional
environment of cloud become imperative for the development of security solutions to protect
.data and enhance the standards of control
Threats

?

The benefits of cloud computing looks fantastic, especially for those who have serious
reservations about the ability of a group of information technology to meet their business
needs. Indeed, the strategy is to resume public cloud service is necessary, such as
outsourcing. However, it is not considered outsourcing fully smart move, as I learned many
institutions during the period following the online business management. When any user can
.holds a credit card to buy the services they want, the problem becomes even worse
.So be aware of the following
:Some information managers feeling threatened
Threaten to deliberate on computing service cloud causing a significant impact in
reducing the number of servers and resources team work. For the information of those
managers who development positions during their career in technology management,
rob cloud service mainly management technology, which lets information managers
are wondering about their role. But it represents an opportunity for information
.managers to pour their attention on strategy and not on the technology
Focusing on the strategic director of information requires the development of a whole

.i

new set of skills, and it must be put into consideration when moving to cloud
computing. Certainly there are many aspiring information managers who look at
existing services on the cloud service as an opportunity because it allows flexibility
.and cost savings
