The article outlines the process of establishing connectivity between two Aerospike clusters using the Cross Data Center Replication (XDR) feature to seamlessly transfer data from a source to a destination cluster, particularly within a Kubernetes environment. It addresses the challenge of network visibility by placing a proxy server in front of a private Kubernetes destination cluster. The setup involves installing the Kubernetes Operator, configuring both source and destination clusters, and setting up an XDR proxy to manage data replication efficiently while resolving potential update conflicts. The guide includes practical steps for implementing this configuration, including the use of Kubernetes commands and YAML files to create and manage the required resources, ensuring that data is successfully replicated across clusters. Additionally, it demonstrates the use of Aerospike's benchmarking tool to test data flow and highlights the scalability of XDR proxies, emphasizing the system's reliability and resilience in mitigating cluster unavailability risks through asynchronous data replication.
