摘要： Techniques are described for selecting an optimal data center for instantiating a first cloud service. Embodiments of the invention receive a request specifying a topology of a first cloud service to be hosted by one of a plurality of data centers which provide computing resources to host a plurality of cloud services. A suitability value is then determined for each of the data centers which measures a fitness of the data center for instantiating the first cloud service. In one embodiment, the suitability value is determined by calculating a plurality of metric values for the data center, normalizing the metric values and calculating a weighted average of the normalized values. One of the data centers is then selected for instantiating the first cloud service, based at least in part on the determined suitability values.

摘要： In one embodiment, a method comprises receiving a request for a distributed service, the distributed service offered by a service provider via a data communications network having service delivery locations reachable via a prescribed physical topology; identifying the service delivery locations within a prescribed logical topology overlying the prescribed physical topology, the prescribed logical topology segregating the distributed service from other network traffic on the prescribed physical topology; and identifying one or more of the service delivery locations optimized for providing the distributed service to at least one service consumption location in the prescribed logical topology according to a prescribed service level agreement with the service provider.
摘要翻译：在一个实施例中，一种方法包括：接收对分布式服务的请求，由服务提供商经由经由规定物理拓扑可到达的服务递送位置的数据通信网络提供的分布式服务; 识别覆盖规定物理拓扑的规定逻辑拓扑内的服务传递位置，规定的逻辑拓扑将规定的物理拓扑上的分布式服务与其他网络流量隔离; 以及根据与所述服务提供商的规定的服务级别协议，识别针对规定的逻辑拓扑中的至少一个服务消费位置来优化的用于将所述分布式服务提供给所述分布式服务的一个或多个服务递送位

摘要： In one embodiment, a method comprises identifying prefix groups for searchable character symbols, each prefix group having a corresponding searchable character symbol comprising at least one searchable character; assigning at least one prefix group to each of a plurality of distributed hash table nodes in a network, each distributed hash table node containing at least one of the prefix groups, each distributed hash table node assigned a corresponding prescribed keyspace range of a prescribed keyspace, each distributed hash table node configured for storing data records having respective primary data record keys within the corresponding prescribed keyspace range; and assigning secondary indexes that start with one of the searchable character symbols to the corresponding prefix group in the associated distributed hash table node, enabling any prefix search starting with the one searchable character symbol to be directed to the corresponding prefix group in the associated distributed hash table node.
