    摘要: Techniques for provisioning and decommissioning web servers in an automated manner. In one embodiment, a threshold value relating to an operational metric of a web server can be stored. The metric can be monitored as the web server receives requests. If the metric exceeds the threshold value, additional web servers can be automatically provisioned to handle a portion of the requests. If the metric falls below the threshold value, the additional web servers can be automatically decommissioned. In another embodiment, information can be logged pertaining to web server requests received over time. Based on this information and a threshold value, patterns of high/low server load can be determined and a policy can be generated identifying time intervals during which additional web servers should be provisioned (or existing web servers should be decommissioned). The policy can be used at server runtime to provision or decommission web servers at the identified intervals.

    摘要: The present invention includes a network service access method. In one embodiment, such a method comprises: forwarding the domain name resolution requests to a local domain name server of each Internet service provider providing services through access link corresponding with the Internet service provider; receiving Internet Protocol address on the domain name resolution requests which the local domain name server of each Internet service provider returned from the corresponding access link; selecting the Internet Protocol address according to line state of the access link of each Internet service provider providing services and returning the selected Internet Protocol address to the user equipments; and visiting network services by the access link of the Internet service provider returning the selected Internet Protocol address.

    摘要: Techniques for balancing network load at network devices in a virtualized computing environment are disclosed. In one embodiment, a first network device having network load above a threshold value is determined. Further, a first host coupled to the first network device is identified. The first host executes a workload that transmits and receives network traffic via the first network device. If the first host is not coupled to any other network device, the network load at the first network device is reduced by initiating migration of at least a part of the workload to a second host coupled to any other network device. If the first host is coupled to a second network device, the network load at the first network device is reduced by instructing a virtual switch of the first host to route at least a part of the network traffic between the workload and second network device.

    摘要: Generally described, the present disclosure is directed to managing request routing functionality corresponding to resource requests for one or more resources associated with a content provider. The processing of the DNS requests by the service provider can include the selective filtering of DNS queries associated with a DNS query-based attack. A service provider can assign DNS servers corresponding to a distributed set of network addresses, or portions of network addresses, such that DNS queries exceeding a threshold, such as in DNS query-based attacks, can be filtered in a manner that can mitigate performance impact on for the content provider or service provider.
