Cloud computing is a novel computing paradigm, which connects plenty of computing resources and storage resources via Internet. Cloud computing provides a number of high-quality services, such as cloud storage, outsourcing computing, and on-demand self-service, which have been widely accepted by the public. In cloud computing, by submitting their tasks to cloud, plenty of applications share huge computation and storage resources. However, how to schedule resource efficiently is a big challenge in cloud computing.In this paper, we propose a SLA-aware resource algorithm to enable cloud storage more efficiently. In our scheme, we take advantage of the back-end node space utilization and I/O throughput comprehensively simultaneously. We compare and contrast the existing scheduling storage policies by implementing those algorithms. The extensive tests show that our algorithm achieves a considerable improvement in terms of violation rate and the number of used hosts.

支持SLA的云存储资源调度算法

云计算是一种新颖的计算范例，它通过Internet连接大量计算资源和存储资源。云计算提供了许多高质量的服务，例如云存储，外包计算和按需自助服务，这些服务已被公众广泛接受。在云计算中，通过将其任务提交到云，许多应用程序共享巨大的计算和存储资源。然而，如何有效地调度资源是云计算中的一大挑战。本文提出了一种支持SLA的资源算法，以更有效地实现云存储。在我们的方案中，我们同时全面利用了后端节点空间利用率和I / O吞吐量。我们通过实现这些算法来比较和对比现有的调度存储策略。
