How to Set up a Distributed Elixir Cluster on Amazon EC2

Thank you for writing things!

Ok, i just registered here while learning elixir and was curious to know how shall I distribute my tiny little services as nodes in a cluster over N networks and voilà there’s a topic with a fine article. This elixir community is awesome and btw bought your book

Best. Comment. Ever. <3

<3! Thanks!

Shared your post on the Spanish group of Elixir, they loved it!

Cheers.

This makes me very happy.

Awesome! Thank you so much for putting time into this.

Would love to see how to go about this in an auto-scaling environment (in which the nodes dynamically created and removed, and thus, the hosts are not known at deployment)

Yes, details on how @bentanweihao would recommend to go about in an auto scaling environment would be awesome!

Thanks for writing this up

A few questions

1. How secure is the communication between nodes? Does it happen in clear text?
2. I see that you can execute code on other nodes, are there any particular instances in a phoenix app where this could be useful? The way it is setup in your post HAProxy would distribute the load regardless of the phoenix apps being in a cluster. Do you see any scenarios where cross node communication may be useful?

1. I think you will want to encrypt the connection
