Service Quality Assurance And Scheduling Method Based On Sla Research And Implementation

IaaS is the current cloud computing as an important form of expression; its entire cloud computing system plays a crucial role in the basis. IaaS delivered basic infrastructure resources to the user. So that users do not have to buy or maintain hardware and system software, they can directly build their own system platform on the platform, to deploy their own applications. In the actual operation, how to ensure the quality of service QoS of resource services according to the SLA content, how to custom SLA management, allocation and scheduling of resources, all those issues need to be solved. Therefore, the research of the IaaS platform resources service has important theoretical and practical significance.This paper is written based on the cloud computing services management system (CBMS) in Huawei cloud computing and its support network project that laboratory undertaken and thesis work includes the following aspects:1. Analyze and summarize of the research status of the theories and methods related to QoS, SLA, resource scheduling strategy and some other issues currently facing.2. Proposed QoS definition of resource service, and first applied characteristics and features of characteristic index of resource service, disused SLA of resource-oriented, described the SLA management of resource service, proposed and described in detail the quality of service management processes based on SLA.3. Proposed a SLA-based service-oriented infrastructure platform system architecture.4. Specific to the problem of the scheduling of automatically increase or migrate virtual machine resource requests, we adopt priority scheduling strategy to solve this scheduling problem. In this paper, We gave the method that how to get the priority characteristic parameters according to the SLA, and used a kind of comprehensive priority table design method to determine the final priority, Finally gave the process of the resources scheduling strategy based on SLA.5. On the basis of theoretical studies, we designed and developed cloud computing services management system (CBMS) as a business layer subsystem in cloud computing and its support network which developed by Huawei and Northwestern University. And this system has been delivered.
