Abstract: In response to a disaster recovery trigger, a disaster recovery controller blocks all traffic to the gateway associated with the active deployment by updating the traffic routing policy of a DNS server. The disaster recovery controller instructs nodes of storage resources in the active deployment to synchronize with storage resources in the standby deployment. After synchronization is completed, the disaster recovery controller updates the DNS traffic routing policy to allow traffic to be sent to the gateway of the standby deployment. Clients of a collection of cloud supported services use a network administration tool to periodically query for a DNS record associated with current regional endpoint of the active gateway, updating their locally cached endpoint identifier with the identifier of the record.

Abstract: The present disclosure involves systems, software, and computer implemented methods for distributed monitoring in clusters with self-healing. One example method includes determining, by a monitoring agent of a first node of a cluster, a self-monitoring check to perform for the first node. The first node is among multiple, other nodes included in the cluster. In response to receiving a successful status for the self-monitoring check, a registry in the first node is updated with the successful status. The registry includes node statuses for each node in the cluster. In response to receiving an unsuccessful status for the self-monitoring check, the monitoring agent performs at least one corrective action on the first node and updates the registry in the first node with a result of the at least one corrective action. The registry is broadcasted to each of the other nodes in the cluster as an updated registry.

Abstract: The present disclosure involves systems, software, and computer implemented methods for distributed monitoring in clusters with self-healing. One example method includes determining, by a first instance of a monitoring agent of a first node of a cluster, whether an error condition in a first registry included in the first node is present, where the error condition is associated with a second node of the cluster. In response to determining that the error condition associated with the second node is present in the first registry, the first instance of the monitoring agent performs at least one corrective action on the second node. A result of that action is determined, and the first registry in the first node is updated with the result. The first registry is then broadcast to each of the other nodes in the cluster other than the first node as an updated registry.

Abstract: One embodiment of the present invention provides a switch that is a member of a fabric switch. The switch includes a keepalive response module that identifies a keepalive response packet that does not correspond to any keepalive packet previously transmitted by the switch. The switch also includes a switch identifier extraction module that extracts a switch identifier from a payload of the keepalive response packet, where the switch identifier corresponds to another member switch in the fabric switch. The switch further includes a forwarding module that constructs a packet that includes the payload and is destined to the other member switch.
