摘要
为对SaaS应用的多租户进行性能隔离,提出基于服务等级归类的多级队列调度方法。通过将大的请求进行分割,充分利用存储和网络资源的并行性,使系统可以优先处理服务等级高的租户请求。QoS可调度性验证方法表明,在资源充足的情况下,系统能够满足各个级别租户的QoS(Quality of Service)需求。
In order to achieve performance isolation for multi-tenant of SaaS application,this paper proposes a service class classification-based multi-level queue scheduling method.By segmenting large request and making full use of parallelity of storage and network resources,the method enables the system to tackle the requests of tenants with higher service level with priority.QoS schedulability verification method shows that if there are sufficient server resources,QoS requirements from every level can be satisfied by the system.
