    摘要: Embodiments of automated cloud service performance prediction are disclosed. The automated cloud service performance prediction includes extracting a parental dependency graph (PDG) for a webpage. The PDG encapsulates one or more dependency relationships for each web object in the webpage. The prediction further includes determining an original page load time (PLT) and original timing information of a webpage. The prediction also includes simulating a page loading of the webpage based on adjusted timing information of each web object and the PDG to estimate a new PLT of the webpage. The prediction additionally includes comparing the original PLT of the webpage to the new PLT of the webpage to determine whether the adjusted timing information increased or decreased the new PLT of the webpage.

    摘要: Techniques and systems for providing optimization of traffic routing for data centers are disclosed herein. In some embodiments, a method may include identifying a plurality of available source sites and paths or routes between an online service provider (OSP) and a destination prefix. A traffic manager may measure a cost for each of the plurality of available paths. In some instances, the traffic manager may also measure a performance value for each of the available paths. The traffic manager may then select one of the available source sites and paths as a preferred source site and path that has a minimized cost for an instance of the performance value when compared to other paths of the plurality of available source sites and paths. In further embodiments, the traffic manager may rewrite a routing table and DNS mapping to implement the preferred source site and path as the default source site and path between the OSP and the destination prefix.

    摘要: Techniques are described for generating a user interface for visualizing a cloud service based on status and performance data of the cloud service obtained from data stores. A configuration file including declarative code may declare particular queries to status/performance data sources. The configuration file may also declare particular queries to topology data sources to obtain topology information. In accordance with the obtained information, objects representing the cloud service may be displayed. The objects correspond to particular hardware and software components, or logical grouping thereof, that are identified by the topology information.

    摘要: A system that includes multiple hosts, each running a plurality of virtual machines. The system may be, for example, a cloud computing environment in which there are services and a service coordination system that communicates with the hosts and with the services. The services include a middleware management service that is configured to maintain per-tenant middleware policy for each of multiple tenants. The middleware management service causes the middleware policy to be applied to network traffic by directing network traffic to a middleware enforcement mechanism. This middleware policy is per-tenant in that it depends on an identity of a tenant.

    摘要: Traffic in a cloud is controlled by the nodes participating in the cloud. Tenants of the cloud each have a ratio. On any given node, a current transmission rate of the node is allocated among the tenants of the node, or more specifically, their execution units (e.g., virtual machines) on the node. Thus each tenant receives a predefined portion of the transmission capacity of the node. The transmission capacity can vary as conditions on the network change. For example, if congestion occurs, the transmission capacity may be decreased. Nonetheless, each tenant receives, according to its ratio, a same relative portion of the overall transmission capacity.

    摘要: Computerized methods, systems, and computer-readable media are provided for establishing and managing a virtual network (V-net) and virtual machine (VM) switches that enable protected and isolated interconnections between members of the V-net. The V-net members include an originating network adapter that generates data packets addressed to a destination network adapter. Upon detecting data-packet generation, a source-side VM switch accesses a forwarding table associated with the V-net, ascertains a destination-side, VM-switch locator that corresponds to an identifier of the destination network adapter, and modifies the data packets to include the identifier. The forwarding table represents a mapping between the members of the V-net and VM switches located on respective nodes within the data center. In operation, the mapping enforces communication policies that govern data-packet traffic. Upon receiving the data packets, the destination-side VM switch restores the data packets and forwards them to the destination network adapter.
