随着对计算和存储器的需求的增加，分布式计算系统已经吸引了很多关注。资源分配是分布式系统中最重要的挑战之一，特别是当客户端有服务水平协议（SLA）时，系统的总利润取决于系统如何满足这些SLA。针对云计算环境下的多层应用，研究了一种基于SLA的资源分配问题。给出了总利润的上界，并提出了一种基于力导向搜索的求解算法。处理、存储器需求和通信资源被认为是执行优化的三个维度。仿真结果验证了该启发式算法的有效性。
With increasing demand for computing and memory, distributed computing systems have attracted a lot of attention. Resource allocation is one of the most important challenges in the distributed systems specially when the clients have Service Level Agreements (SLAs) and the total profit in the system depends on how the system can meet these SLAs. In this paper, an SLA-based resource allocation problem for multi-tier applications in the cloud computing is considered. An upper bound on the total profit is provided and an algorithm based on force-directed search is proposed to solve the problem. The processing, memory requirement, and communication resources are considered as three dimensions in which optimization is performed. Simulation results demonstrate the effectiveness of the proposed heuristic algorithm.
