Hala Alotaibi;CSCI780;Dr. Kevin Lillis;9/6/2014;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;so?called 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;?;.1;interested in relating to end?user applications such as e?mail systems, customer;relationship management applications, common software and systems management.workflow;Provide software platforms as a service (PAAS): a layer of cloud computing;.2;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;.3;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 hard?ware. It;also achieved significant savings of up to 70% which is the percentage allocated in;any company for the operating system, or the so?called Operation?System also;contribute to cloud computing to cut an estimated 40 to 60% of the budget of 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 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;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;IT?friendly 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 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 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?

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
