The Design And Implementation Of QoS Based Resource Allocation Private Cloud Platform

In recent years,cloud computing technology has gradually matured,this new type of resource use and delivery model has been widely recognized by the industry and acceptance.In cloud computing,private cloud because it can provide more secure,efficient,reliable and personalized IT infrastructure services,has gradually become the majority of enterprises to choose cloud computing solutions.With the gradual popularization of private cloud,it has become an important research direction in the private cloud field around how to improve the resource utilization ratio and reduce the operating cost in the early stage of Qo S.Because of the timeliness and flexibility of the use of cloud services,cloud services are increasingly high,so it is not easy to allocate the costs and resources from the economic costs and the use of time.Need to consider the problem,in the face of frequent users of the user’s requests for service resources,to achieve the optimal,efficient allocation of resources and utilization,it must have the optimal allocation of resources,the method of resource allocation.And for its own data centers,the establishment of a set of Qo S based distribution of resources of private cloud platform system has become an urgent demand for its own data center companies.This paper first analyzes the status quo of the enterprise’s own data center construction,and refers to the problems that arise from the use of data centers from the use to operations.On the basis of summarizing domestic and foreign related research and practice results,the successful experience of private cloud platform is used to design and implement a private cloud platform based on Qo S resource.The main work is as follows:(1)A resource allocation algorithm based on Qo S is established.In the process of design and implementation,this paper further optimizes the function of resource allocation by comparing the modified method.Then the cloud load balance model is built,and the resourceallocation algorithm based on Qo S is designed and implemented.So as to achieve the purpose of effective utilization of resources through the allocation of resources and recycling.(2)A set of different backup and recovery scheme for cloud storage is designed.Ceph distributed storage and snapshot technology to achieve faster backup speed and less resource consumption of different backup solutions,in the process of data backup and recovery,only to the front and back of the different parts of the backup,compared to the common full data backup,data backup and recovery efficiency has been significantly improved.(3)Based on the above work,a private cloud platform based on Qo S is designed and realized.The platform uses SOA architecture,which is easy to integrate with other information systems.It can realize the seamless integration of the real business units,which makes the use and management of private cloud resources more simple and efficient.The platform is constituted by the infrastructure resources layer,the business arrangement service layer and the operation management portal layer.Infrastructure resource layer is responsible for the management and scheduling of hardware resource and resource pool.The service layer is mainly responsible for the combination of cloud resources in the service operation model.The operation management portal is primarily responsible for the simple and intuitive user interface.The implementation of the platform greatly improves the resource utilization of the enterprise’s own data center,and realizes the fast,accurate and real-time allocation of virtual resources through the resource allocation algorithm based on Qo S.It can control the Qo S state information,and facilitate the expansion and recycling of resources.
