Study On Cloud Computing And Its Application In Smart City

With the development of information technology in city,the constant expansion of city size,smart city increasingly complex needs from the resources including hardware and software.How to integrate resources to provide quality services has become to the most urgent problem to solve.On the basis of the study of cloud technology and cloud service,this paper designs a cloud computing data center service platform in order to provide support to build a sharing,efficient smart city.It's the applied research on information technology in smart city which integrated information technology into city's daily management,various departments daily office and other fields using the mode of cloud service.The overall program of cloud computing data center construction,hardware and software deployment and research the resource scheduling policy of cloud computing data centers are designed.On this basis,a cloud computing resource scheduling strategy based on greedy algorithm is proposed,making cloud computing resource scheduling strategy not only surmount the disadvantages of the traditional resource scheduling algorithm,but also shorten the time for computing the tasks and improve resource utilization.Paper Details are as following:First,the advantage of cloud computing applications in the smart city is elaborated,summaries the theoretical knowledge of cloud computing and smart to further analyze detailedly cloud computing virtualization technology and resource scheduling technology.Second,cloud computing resource scheduling strategy based on greedy algorithm.a double balance algorithm is presented which uses greedy algorithm to decompose the problem,and proposes the greedy model of resource scheduling,to make up for the deficiency of traditional resource scheduling algorithm,and the greedy algorithm and cloud computing resource scheduling problem are a good fit.After a reasonable theory analysis,the use of cloud computing simulation platform CloudSim,make simulation to the promoted algorithms to verify the effectiveness of the algorithm.Through experimental comparison,the greedy algorithm can achieve the load balancing of resources and shorter execution times,more suitable for cloud environments.Finally,the construction of cloud computing data centers.Analysis the necessity and goals of smart xinyi cloud computing data center construction,as well as the demand analysis of cloud computing data center security,dependability,expandability,disaster tolerance and so on,proposing cloud computing data center overall architecture,planning scheme and the deployment of software and hardware,and ultimately completed the construction of cloud computing data center.
