Abstract: Systems and methods for geographically distributed node replication include a first node which receives a message from a client based on a proximity of the first node to the client, the message transmitted to the first node via anycast routing from the client. The first node may replicate the message to a first subset of the geographically distributed system of nodes based on a geographic proximity of nodes within the first subset. The first node may publish the message to a data feed of a message bus for the system of nodes, to cause at least one node of the system of nodes to receive the message from the first node, the at least one node outside the first subset and subscribing to the data feed of the first node.

Abstract: The present solution provides systems and methods for a GSLB service to access a first plurality of measurements of network latency between a plurality of access-points and the first client device and a second plurality of measurements of network latency between the plurality of access-points and one or more of data centers. The GSLB service can receive, from the one or more data centers, health of an application deployed across the one or more data centers. The GSLB service can determine, according to the first plurality of measurements, the second plurality of measurements and the health of the application, a first data center of the one or more data centers and a first access-point of the plurality of access-points. The GSLB service can send, to the first client device, a domain name system (DNS) response identifying the first access-point and the first data center.
