Abstract: Resource allocation strategy has been the hot and difficult research topic in the field of cloud computation. Research and analysis of current resource allocation strategies were carried out. Firstly, the challenges facing cloud platform resource allocation were analyzed. Then the formalization description of cloud platform resource allocation was given. The current mainstream of resource allocation strategies were described from the perspectives of heuristic allocation algorithms, economic theory based strategy, and other allocation strategies, and their advantages and disadvantages were discussed. Finally, a comprehensive comparison of the mainstream strategies based on specific indicators was made, and some future research directions were pointed out.

Key words: cloud computing, resource allocation, algorithm strategy, heuristic algorithm, economic game theory, awareness of energy

摘要： 资源分配策略的研究一直是云计算领域研究的热点和难点。针对当前已有的资源分配策略进行了深入调研和分析,首先简要分析了云平台资源分配存在的挑战;然后给出了云平台资源分配的形式化描述;在此基础上，从启发式分配算法、基于经济理论的策略，以及其他分配策略三个方面对当前主流的资源分配策略进行描述，分析其优缺点;最后结合具体指标对主流策略进行了综合比较，并指出未来的研究方向。
