一种基于双向拍卖和细胞膜优化的云资源分配机制的研究

摘要

云计算是一种新的计算模型，它将底层的基础设施资源虚拟成资源池，并以服务的形式提供给用户使用。合理地分配和使用云资源是保障云安全的前提条件。文章针对云资源和云市场的特点，结合经济学知识，提出一种基于双向拍卖和细胞膜优化的云资源分配机制。在该机制中，通过双向拍卖给云资源定价，并给出3个指标来评价资源分配方案，同时引入目标值作为优化目标，使用细胞膜优化算法得出最优的资源分配方案。仿真结果表明，该分配机制是可行且有效的。%Cloud computing is a new computing paradigm which virtualizes the underlying infrastructure resources into a resource pool and the resources are provided to cloud users in the form of services. Reasonable distribution and use of cloud resources is a prerequisite for ensuring the security of the cloud. Based on the characteristics of cloud resources and cloud market, combining with the knowledge of economics, this paper proposes a cloud resource allocation mechanism based on double auction and cell membrane optimization algorithm. In this mechanism, cloud resources are priced by double auction and three criterions are introduced to evaluate the effectiveness and efficiency of the proposed resource allocation scheme. The objective value is introduced as the optimization objective and optimal resource allocation scheme is obtained by using the cell membrane optimization algorithm. The simulation results show that the proposed mechanism is both feasible and effective.
