    摘要： Virtual machine migration is described. In embodiment(s), a virtual machine can be migrated from one host computer to another utilizing LUN (logic unit number) masking. A virtual drive of the virtual machine can be mapped to a LUN mask associates the LUN with a host computer. The LUN mask can be changed to unmask the LUN to a second computer to migrate the virtual machine from the host computer to the second computer.

    摘要： Architecture that facilitates the virtual specification of a connection between physical endpoints. A network can be defined as an abstract connectivity model expressed in terms of the connectivity intent, rather than any specific technology. The connectivity model is translated into configuration settings, policies, firewall rules, etc., to implement the connectivity intent based on available physical networks and devices capabilities. The connectivity model defines the connectivity semantics of the network and controls the communication between the physical nodes in the physical network. The resultant virtual network may be a virtual overlay that is independent of the physical layer. Alternatively, the virtual overlay can also include elements and abstracts of the physical network(s). Moreover, automatic network security rules (e.g., Internet Protocol security-IPSec) can be derived from the connectivity model of the network.

    摘要： In a multi-tenant environment, machines across the Internet, belonging to a particular subscription are securely enrolled with the tenant's subscription. Authentication of the machines is delegated to each of the tenant's own on-premise authentication mechanism The trust relationship with the tenant's authentication service is used to validate the security token presented by the machine being authenticated. Once authenticated, the machine has authorization (e.g. SSL machine cert for identity, security token, etc.,) to access the subscription. Each tenant within the multi-tenant environment can provide its own level of authentication. The machine presents the security token to the multi-tenant environment for requests for resources (e.g. services/content) from a user. When a request is received from a machine to access a resource, the multi-tenant environment determines from the issued token whether or not the machine is authorized to access the requested resources.

    摘要： A virtual machine comprises a unique identifier that is associated with one or more encryption keys. A management server encrypts the virtual machine's virtual hard disk(s) using the one or more associated encryption keys. The management server further provides the one or more encryption keys to a limited number of one or more servers in a system. Only those one or more servers that have been provided the one or more encryption keys can be used to load, access, and/or operate the virtual machine. The management server can thus differentiate which virtual machines can be operated on which servers by differentiating which servers can receive which encryption keys. In one implementation, a management server encrypts all virtual machines in the system, but encrypts virtual machines with sensitive data with a limited set of encryption keys, and further provides those encryption keys to a limited set of trusted servers.

    摘要： Architecture that facilitates communications between two network nodes of the different networks by providing a routing mechanism that uses alternative modalities driven entirely by policies that are authored and stored in a computing cloud and enforced on the client. This allows the selection of one network path over another path based on criteria such as, physical location of the hosts and service level agreements (SLAs) to be provided, for example. With respect for path selection, a packet can be routed through a datacenter closest to the hosts. With respect to SLAs, there may be different SLAs available to different clients. For clients with the highest bandwidth/uptime or other guarantees, a network path different from other types of clients can be selected. Additionally, connectivity can be allowed or disallowed based on other kinds of policy rules such as a virtual circle to which the hosts may belong.

    摘要翻译： 通过提供一种路由机制来促进不同网络的两个网络节点之间的通信的架构，该路由机制使用完全由被编写并存储在计算云中并在客户端上执行的策略驱动的替代模式。 这允许例如基于诸如主机的物理位置和要提供的服务水平协议（SLA）等标准来选择另一路径上的一个网络路径。 对于路径选择，可以通过最靠近主机的数据中心路由数据包。 对于SLA，可能会有不同的SLA可用于不同的客户端。 对于具有最高带宽/正常运行时间或其他保证的客户端，可以选择不同于其他类型的客户端的网络路径。 另外，可以基于其他类型的策略规则（诸如主机可能属于的虚拟圆）来允许或不允许连接。
