In order for a service to talk to another, it needs to know two things: the name of the destination service, and whether or not the traffic should be secure. The abstractions that Eureka provides for this are Virtual IPs (VIPs) for insecure communication, and Secure VIPs (SVIPs) for secure.

In both cases, when using virtually-synchronous replication, the process will require certification from each node and local (by node) write; as such, the number of writes is NOT distributed across multiple nodes but duplicated.

In such a situation I’d expect to see unusually high latencies, but normal throughput).
