The summary of the text is that this post outlines how to establish connectivity between two Aerospike clusters using Kubernetes Operator, enabling high availability for critical data systems by leveraging Aerospike's Cross Datacenter Replication (XDR) feature. The process involves deploying a proxy server in front of the private Kubernetes destination cluster, setting up the xdr-proxy, and scaling the XDR proxies. The post also touches on the importance of dependable resiliency with Aerospike's XDR feature, which provides a reliable solution for mitigating the risk of cluster unavailability by asynchronously replicating data between data centers.
