摘要： A system is provided for migrating a VM over a WAN. A first server has a VM. The first and second servers are operatively connected over the WAN by a virtual private local area network service. The first server migrates the VM to the second server by coping files and state of the VM to the second server without interrupting the interactive software on the VM. During a last round of migrating the VM, for packets intended for the VM on the first server, the first server buffers the packets in a buffer as buffered packets. Instead of delivering the buffered packets to the VM, the first server transmits the buffered packets to the second server. The second server plays the buffered packets to the VM migrated to and operating on the second server, such that buffered packets are played before current packets currently received from the clients are played.

摘要： Methods of predicting datacenter performance to improve provisioning are described. In an embodiment, a resource manager element receives a request from a tenant which describes an application that the tenant wants executed by a multi-resource, multi-tenant datacenter. The request that has been received is mapped to a set of different candidate resource combinations within the datacenter, where each candidate resource combination can be used to execute the application in a manner which satisfies a high level constraint specified within the request. This mapping may, for example, be performed using a combination of benchmarking and an analytical model. In some examples, each resource combination may comprise a number of virtual machines and a bandwidth between those machines. Data relating to at least a subset (and in some examples, two or more) of the candidate resource combinations is then presented to the tenant.

摘要翻译： 描述了预测数据中心性能以改善配置的方法。 在一个实施例中，资源管理器元件接收来自租户的请求，所述请求描述了租户希望由多资源，多租户数据中心执行的应用。 已经接收到的请求被映射到数据中心内的一组不同的候选资源组合，其中每个候选资源组合可以用于以满足请求中指定的高级约束的方式来执行应用。 例如，该映射可以使用基准测试和分析模型的组合来执行。 在一些示例中，每个资源组合可以包括多个虚拟机以及这些机器之间的带宽。 然后将与候选资源组合的至少一个子集（并且在一些示例中，两个或更多个）相关的数据呈现给租户。
