摘　　要：针对企业部署云资源的复杂需求和不稳定性问题,以企业多实例组合采购决策为研究对象,建立了两阶段云资源采购决策模型,考虑包含多类型虚拟机的长期合同实例和竞价实例组合,以此来降低采购过程中的风险和成本.结合维基百科2015年的8760条数据进行实验,通过对长期合同单类型实例的采购、长期合同+短期按需的组合采购、长期合同+短期竞价的组合采购方式的结果对比,证明了长期合同实例和竞价实例组合的两阶段采购方式能在采购过程中为企业带来更低的成本,实现更高的利润.Aiming at the complex and instability requirements of cloud resources deployment for enterprises,this paper takes the enterprise multi-instance combination procurement decision as the research object,and establishes a two-stage cloud resource procurement decision model,considering the reserved instance and spot instance combination including multiple types of virtual machines,in order to reduce risks and costs in the procurement process.The analysis bases on 8760 data in 2015 of Wikipedia,and compares the results of the reserved instance procurement,reserved instance & on-demand instance combination procurement,reserved instance & spot instance combination procurement.It was proved that the two-stage procurement method combined with the reserved instance & spot instance can bring lower costs to the enterprises and achieve higher profits in the procurement process.
