| Along with the development of China telecom market is Gradually opened and telecommunication reform is speeding up, the traditional telecommunication market environment has had the huge change, the comprehensive competition open market pattern formed gradually, internationalization operation tendency day by day in relief.The IT support system took one of Guangdong telecommunication core competitive powers, can promote the Guangdong telecommunication effectively the management and the management level, the telecommunication brings the huge economic efficiency for Guangdong.The Guangdong telecommunication promotesthe different type the service, by wins more users, increases the business volume and the income.Is day by day huge along with the Guangdong telecommunication business volume, the different type IT support system should have to construct, the system scale is huge gradually, theservice and the construction are complex day after day, all day after day accumulated some questions at the engineering construction and the operation maintenance aspect.If various subsystems independent construction and the management, the project invests in a big way, the system result is small; The equipment cost is high, the use factor is low; The system construction time span is big, user’s service production cycle is long; The hardware breakdown appears thenumber of times frequency to be dense, the solution speed is slow.At system Rong Zai, the backup aspect way quite is primitive, creates the system safety to be low.Above question primary cause has not had to the hardware infrastructure resources makes the master plan, the reasonable resources mixes.The cloud computation is one kind enables the user to be able convenient, according to have to visit in the network the shared resource pattern, the shared resource including the network, the server, the memory, the application procedure and the service and so on.These computation resources may supply fast and the issue, fast accurately provides the service through theInternet to the user.The Guangdong telecommunication in order to solve IT to support the systems engineering construction and the operation management existence question, can carry onthe expansion and the optimization well to the IT support system, responds the user grade ofservice and the service demand quickly, the Guangdong telecommunication introduces gradually the cloud computation technology in the IT support system construction and the operation.Speaking of the Guangdong telecommunication IT support system user, all revolves QoS to system various demand (Quality of Service) the total expenditure, the total period of revolution, the system reliability (drop rate), the system to swallow the measure (band width) and so on the performance.This article begins from these aspects to analyze, the research suits the Guangdong telecommunication IT support system construction the pattern.This article in view of the Guangdong telecommunication IT support system characteristic and the current existence main question, unifies in the IT support system construction to thecloud computation technology demand, unifies based on the QoS cloud computation task scheduling strategy, studies based on the cloud computation construction Guangdong telecommunication IT support system construction pattern.Carries on the modelling using cloud computation simulation simulation tool CloudSim, the simulation different scene, to carries on the quantification and the comparison based on the QoS cloud computation resource distribution and the task scheduling result, the analysis obtains suits the Guangdong telecommunication IT support system construction reasonable and the feasible plan.The experimental result proved this article studies the model and the task scheduling strategy can enhance the cloud computing system duty effectiveness value, enhances the cloud computing system the operating efficiency, the resources effective use factor. |
