Question;Hala AlotaibiCSCI780Dr. Kevin Lillis9/6/2014Cloud computingCloud computing latest major shift in ideas and applications related to informationtechnology services, especially with regard to infrastructure solutions that rely on institutionsto facilitate their operations, and found a lot of institutions, large and small enlist in this newsystem and predicted a recent study for the Foundation IDC Global specialized in researchthat Cloud computing provides additional revenue for the institutions of more than a trillion.dollars by 2014Definition?Technology is based on the transfer and processing of computer storage space to theso?called cloud, a device server to be accessed via the Internet, and this turn of informationtechnology software products to services. Thus, this technology contributes to the problemsof clearing the maintenance and development of software for information technologycompanies have used, and thus concentrated effort of the beneficiaries to use these servicesonly. And rely infrastructure cloud computing data centers that offer advanced and largestorage 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 classesProviding software as a service (SAAS):layer of cloud computing and more?.1interested in relating to end?user applications such as e?mail systems, customerrelationship management applications, common software and systems management.workflowProvide software platforms as a service (PAAS): a layer of cloud computing.2consists mainly of libraries, programs and intermediates, and updates the runtime andtools needed by developers in updating the software application as a service. Thebenefit 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 serviceThe "infrastructure as a service"(IAAS): they provide the infrastructure for.3computer, and instead of buying servers, software, data center space or a privatenetwork equipment customers purchased these sources as a service completelyindependent. The service description is usually on the basis of utility computing andhow the sources used and thus the cost, which will necessarily reflected on the level ofactivity. The use of cloud computing technology of virtual computing (VirtualizationTechnology) extensively in the model "infrastructure as a service" of their own as ithelps 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 aslarge companies because they will work the system the Out? sourcing, which designed itsmodel of computing allows them to optimize the use of infrastructure, and to achieve thedesired objectives, and thus will be redundant then for creativity at work to be able to deal.with new technologyCloud computing is also an integral part of the industry, data centers and therefore theinformation 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 timeIt 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 simpleand moving, it is also a panacea to counter the negative effects of the economic crisisthat plagued all countries and sectors since the beginning of 2009 and shows that clearin cost savings Finance not inconsistent with the efficient functioning of theapplications and solutions, and at the level of software products, and hard?ware. Italso achieved significant savings of up to 70% which is the percentage allocated inany company for the operating system, or the so?called Operation?System alsocontribute to cloud computing to cut an estimated 40 to 60% of the budget of dedicated to the telecom sector and information technologyFirst, the positives?The main importance in the following pointsCost: low in terms of reducing the purchase price of the equipment, and change the.Alicense application system where service has been made on the basis of itScalability and Availability: where have the services and the sites hosted on the.Bcloud host provider to cloud the possibility of determining the scope at which.demand is always available to usersNo limits of computing and storage: there are no limits for storage and processing.C.on the cloud theory, but there are some obstacles in practiceFocus on the core business rather than IT: where business owners need to focus on.Dtheir core mission rather than trying to address the management of information.technologyProvide resources in a more dynamic: they provide users with the computing.E.resources they need at any time and in a dynamic wayMore Efficient: It does not matter whereabouts of your equipment is the most.important thing that operate well and that the service will be available.FIT?friendly environment (Green IT): cloud computing and virtual environment in.Ggeneral play an important role and effectively in the development of the movementof "Green IT", the technology is green and cloud computing were closely linked, asthe technology of cloud computing is the technology Virtual and works to reducethe number of machinery and equipment used and thus reflected on because it also helps in saving energySecond: the negativesAnd are summarized in the following pointsSecurity: you information are important exist on the Internet, can be trusted storage?.AIf the number of terrorists attacked a number of clouds computing what will be the?fate of your businessPrivacy and data ownership: Is your applications are not ready to deal with after and need to be some adjustments to adapt to the cloud environmentTo ensure the level of service: Is it provides this service is always? What about.Cservice level agreements? What about connecting to the network and site access?servers and various services on the cloudJoint work and integration of services between the clouds: Is there a possibility to.Dmove from a vendor service for another without having to change the texts and theenvironment 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 withthe work of compliance, such as "H, but any AA, S or X (HIPAA, SOX etc.)...."EtcThere is also a cloud Gurmerih and extremely dangerous spread continuously andsteadily around the whole world, with the transfer of data storage digital with harddrives on computers to a system of cloud computing and storage on the Internethas increased the amount of waste digital wasted dramatically during the lastdecade, and includes such wastes digital e?mails The photos and video clips and.E?music that are stored on the Internet without a real need her, and without re?used.againThe challenges?The challenges that hinder the spread of cloud computing including environment ofcloud involves many challenges and gaps several security can not be for security solutionsconventional face, as I mentioned earlier that security is the first concern of the challenges orissues troubling when talking about cloud computing, but it has developed a "OtrendMaekerob" package integrated security solutions and advanced Trend Micro Secure Cloud toprovide protection to remove such concerns as the challenge of this new package of securityrisks, and concerns related to privacy and interoperability at the dissemination of informationin the cloud computing environment. Today, after taking determined parameters of cloudcomputing, and companies began to store massive amounts of data in the institutionalenvironment of cloud become imperative for the development of security solutions to and enhance the standards of controlThreats?The benefits of cloud computing looks fantastic, especially for those who have seriousreservations about the ability of a group of information technology to meet their businessneeds. Indeed, the strategy is to resume public cloud service is necessary, such asoutsourcing. However, it is not considered outsourcing fully smart move, as I learned manyinstitutions 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 threatenedThreaten to deliberate on computing service cloud causing a significant impact inreducing the number of servers and resources team work. For the information of thosemanagers who development positions during their career in technology management,rob cloud service mainly management technology, which lets information managersare wondering about their role. But it represents an opportunity for information.managers to pour their attention on strategy and not on the technologyFocusing on the strategic director of information requires the development of a whole.inew set of skills, and it must be put into consideration when moving to cloudcomputing. Certainly there are many aspiring information managers who look atexisting services on the cloud service as an opportunity because it allows flexibility.and cost savings
