摘要

本文介绍了在大型批处理场内以及在提供云计算服务的站点之间进行虚拟机映像分发的各种机制。这项工作是在大型强子对撞机计算网格(LCG)的背景下提出的，它有两个主要目标。首先，它旨在展示CERN特定的机制，这些机制已经到位，可以在数百个物理主机的大型云基础设施中测试虚拟机映像的预登台。其次，介绍了在LCG站点之间信任和分发虚拟机映像的策略基础。最后给出了使用二叉树和Bit Torrent算法将10gb虚拟机映像分布到400多个物理节点的实验结果。结果表明，图像可以在30分钟内进行预处理。

Image Distribution Mechanisms in Large Scale Cloud Providers

This paper presents the various mechanisms for virtual machine image distribution within a large batch farm and between sites that offer cloud computing services. The work is presented within the context of the Large Hadron Collider Computing Grid (LCG), it has two main goals. First it aims at presenting the CERN specific mechanisms that have been put in place to test the pre-staging of virtual machine images within a large cloud infrastructure of several hundred physical hosts. Second it introduces the basis of a policy for trusting and distributing virtual machine images between sites of the LCG. Finally experimental results are shown for the distribution of a 10 GB virtual machine image distributed to over 400 physical nodes using a binary tree and a Bit Torrent algorithm. Results show that images can be pre-staged within 30 minutes.
