> That's just DNS. No, it's a bit more complicated than that, as chrisboulton explains (so I won't go into detail). You could use a dynamic DNS server such as Consul for discovery, and people do. Last I checked, you still had to fight eagerly caching clients, but that's probably doable. But there's still a host of other issues that Linkerd addresses. Again, I strongly recommend reading about Finagle to understand what this is trying to solve. Another thing Linkerd brings to the mix is instrumentation and tracing. Instead of building this into every single sender and receiver, Linkerd can collect tracing data for you and make it available for other subsystems to ingest, such as Zipkin or Prometheus.
