Understanding supervisor
Hi all,
I need help on understanding supervisor role in “ordinary” web architecture.
I’m thinking the data flow will be like the following (notice the plurals):
client → Load Balancer (LB) → elixir apps → workers
or
client → LB → elixir apps → supervisor → workers
or
client → LB → elixir apps → LB → workers
or
client → LB → elixir apps → message queue → workers
The questions are:
- Where the supervisor should resides?
- Does LB and MQ diminish the role of a supervisor?
Or I might be wrong at all as thinking OTP supervisor as infrastructure layer supervisor.

The supervisor doesn’t do anything to your request. It just sits there and restart crashed processes.

RIght - got carried away there - the BEAM distributes the processes across the all the cores available to the node.
