The abstractions that Eureka provides for this are Virtual IPs (VIPs) for insecure communication, and Secure VIPs (SVIPs) for secure. IPC clients are instantiated targeting that VIP or SVIP, and the Eureka client code handles the translation of that VIP to a set of IP and port pairs by fetching them from the Eureka server.
