title: How does `flux`/`mono`, RabbitMQ, AkkaStream work in big picture in microservies world?
body: <p>i try to grasp what are flux and mono for in big picture.</p>
  
  <p>I get that when microservices talk to each other we can you use quee (like <code>RabbitMQ</code>) to make them talk asynchronously instead of synchronously.</p>
  
  <p>But if i use only <code>flux</code>/<code>mono</code> using <code>HTTP2</code> (to my knowledge) then my microservies already talk to each other asynchronously or not?</p>
  
  <p>If not then what part of the big picture is asynchronous?</p>
  
  <p>There is also <code>Akka streams</code> - is it something like RabbitMQ? A quee that make microservies talk asynchronously?</p>
  
  <p>I would appreciate clarification - thanks.</p>
