云计算的概念极大地改变了当今并行和分布式计算系统领域。云计算使广大用户能够通过互联网访问分布式的、可扩展的、虚拟化的硬件和/或软件基础设施。负载平衡是在分布式系统的各个节点之间分配负载的过程，以提高资源利用率、最小化响应时间和最大化吞吐量，同时也避免一些节点负载过重而其他节点空闲或工作很少的情况。负载均衡确保系统中的所有处理器或网络中的每个节点在任何时刻都完成大约等量的工作。本文提出了一种新的两级模糊云计算动态负载均衡方法。该方法利用模糊逻辑来表征分布式系统中的不确定性。通过模糊逻辑，使用处理器速度和节点队列长度来平衡集群级节点的负载，使用处理能力和集群平均队列长度来平衡云级集群的负载。对比研究表明，该算法在平均响应时间和吞吐量方面优于轮循算法和随机化算法。
The concept of the Cloud computing has significantly changed the field of parallel and distributed computing systems today. Cloud computing enables a wide range of users to access distributed, scalable, virtualized hardware and/or software infrastructure over the Internet. Load balancing is the process of distributing the load among various nodes of a distributed system to improve resource utilization, minimum response time and maximize throughput while also avoiding a situation where some of the nodes are heavily loaded while other nodes are idle or doing very little work. Load balancing ensures that all the processor in the system or every node in the network does approximately the equal amount of work at any instant of time. In this paper, we propose a new two level fuzzy approach for dynamic load balancing in cloud computing. This approach characterizes the uncertainty in a distributed system by using the fuzzy logic. The processor speed and queue length of nodes are used to balance the load of the nodes in cluster level and processing power and average queue length of clusters are used to balance the load of the clusters in cloud level through fuzzy logic. In comparative study, proposed algorithm shows better average of response time and throughput than Round Robin and Randomize algorithms.
