We are exploring ES in our stack. I was looking around for some good architecture diagrams which shows internals of ES like how Netty is used by ES, which protocols needs to be configured and enabled for making cluster work(multicast, unicast), which protocols gets utilized at different layers(application(i guess ES uses Native Elasticsearch binary protocol), network ,etc). I know details of how ES works like sharing indexing, pipelines etc in details, all i am missing more of network level architecture details. Also, i don't think ES runs on any server(like tomcat, wildly etc), it runs as a standalone application ?
Any pointers with above information would be helpful.
Thanks in advance.
