Communication between servers

Intro

In a clustered and/or a replicated environment services needs to speaks to each others. In some database the number of open ports is pretty impressive. For example in CouchBase (a database which I really like) you have plage of ports and so many open ports. Take a look at it.

I think this is some kind of issue.

Possible solution

QUIC

QUIC is a communication protocol. We can make all needed connections goes to one open port.

QUIC gives the power of using rich HTTP API with low latency and optimized bandwidth with multiplex. No need to open many ports, all needed information can be set inside the headers like type of transmission, authentication and any kind of informations. Because QUIC provides a HTTP server, we can expose a standard TCP HTTP as a fallback to clients which can't handle QUIC.

quic-go package looks like a really good starting point to work with.
