you could perform service discovery many different ways. at a really
high level here are a few i can think of:
1. be totally static. place each of your microservices behind an ELB,
use AutoScaling (assuming AWS here).
2. use Zookeeper or Etcd for coordination. Curator has some recipes to
do this for Zookeeper:
http://curator.apache.org/curator-x-discovery/index.html.
3. use akka cluster and specify node roles to differentiate different
microservices:
http://doc.akka.io/docs/akka/2.4.1/scala/cluster-usage.html#Node_Roles.
this requires you to write more code, akka just provides the
framework here.
these kinds of architectural questions are impossible to answer without
knowing your *business requirements* and the architecture you already
have in place. you will get a better response if you do some more
research, evaluate the options you find, then come back and ask very
specific, targeted questions. or you can talk to the fine people at
Typesafe: http://www.typesafe.com/services/consulting (i have no
affiliation with Typesafe, i just think they are smart people :)

Hi,
We need a service registry where all our components will turn to for
discovering the actual URLs which they can use to communicate to other
parts of our system. The service has to provide a load balancing and
fault tolerance. It has to be distributed to prevent a production
outage. In _CAP_
<http://codahale.com/you-cant-sacrifice-partition-tolerance/>terms, it
has to be AP.

Hi,
We are going to use Akka-HTTP as IPC in our new distributed
system that is based on microservice architecture. How to perform
Service discovery for akka-stream/akka-http in distributed
system? What is the best way to implement this?
what are your requirements?
