    摘要: A method and control node (300) for managing cloud resources in a communications network for a client (306A) being served by a primary data center (308) holding service data associated with a cloud service being executed for the client in the primary data center. A first backup data center (310) having free processing and storage resources for the cloud service, is selected based on usage of links between a source node (306) associated with the client and the first backup data center (310). The service data is then saved in the first backup data center (310), thereby enabling the cloud service to be recovered in the first backup data center (310) in case of service failure at the primary data center (308). If the usage of links in potential communication paths between the source node (306) and the first backup data center (310) exceeds a link usage threshold, the saved service data may be transferred from the first backup data center (310) to a second backup data center (312) so that the cloud service can be recovered in the second backup data center (312) instead if needed.

    摘要: 本发明实施例公开了一种分布式负载均衡系统、健康检查方法和服务节点,属于云网络技术领域。包括云管理平台、访问节点以及至少一个服务节点,访问节点和至少一个服务节点为物理服务器,访问节点上运行有第一虚拟负载均衡器,服务节点上运行有至少一个后端服务器。通过目标服务节点上的探测模块发送探测消息探测目标后端服务器的状态,通过探测模块将目标后端服务器的状态共享给第一负载均衡器,从而不仅降低了负载均衡系统中探测消息的数量,还降低了访问节点的信令负载。探测模块部署在目标服务节点上的第一命名空间中;第一虚拟负载均衡器部署在访问节点上的第二命名空间中,第一命名空间与第二命名空间具备相同的IP地址,节省了IP地址资源。

    摘要: Load-balancing data messages are sent by a source node to one or more different groups of destination compute nodes (DCNs). A load -balancer in the source compute node's egress datapath receives each data message sent from the source compute node and determines whether the data message is addressed to one of the DCN groups for which the load-balancer spreads the data traffic. When the received data message is not addressed to one of the load-balanced DCN groups, the load-balancer forwards the received data message to its addressed destination. When the received data message is addressed to one of the load-balancer's DCN groups, the load-balancer identifies a DCN in the addressed DCN group that should receive the data message, and directs the data message t the identified DCN by changing the destination address in the data message from the address of the identified DCN group to the address of the identified DCN.

    摘要: A Domain Name System (DNS) server that is operable to apply DNS-based load balancing policies based on geolocation and time of day is described herein. In an embodiment, the DNS server determines a geolocation and a time of day associated with a plurality of DNS queries and then obtains a domain name resolution policy that is associated with one or more of the geolocation and the time of day. The policy specifies a plurality of geographically disparate data centers and a ratio by which domain names are to be resolved thereto. The ratio at least specifies that more domain names are to be resolved to one of the plurality of geographically disparate data centers than another. The DNS server applies the domain name resolution policy to resolve the domain names in the DNS queries.

    摘要: A generation identifier is employed with various systems and methods in order to identify situations where a workload has been reassigned to a new node and where a workload is still being processed by an old node during a failure between nodes. A master node may assign a workload to a worker node. The worker node sends a request to access target data. The request may be associated with a generation identifier and workload identifier that identifies the node and workload. At some point, a failure occurs between the master node and worker node. The master node reassigns the workload to another worker node. The new worker node accesses the target data with a different generation identifier, indicating to the storage system that the workload has been reassigned. The old worker node receives an indication from the storage system that the workload has been reassigned and stops processing the workload.
