Composing Nodes

Our Erlang code is organized into separate applications but these applications are usually tightly coupled with the each other and the node running the code. Some simple design techniques can loosen this coupling and make it easy to compose and recompose your applications into nodes. Bundling your entire distributed application into a single node makes it easier to develop and test. Recomposing applications across nodes makes it easier to scale the applications separately, saving resources and opening new deployment options. The examples use rebar3.

Talk objectives:

Show how to design applications for easy composition into nodes. Describe how to work with shared applications like mnesia and cowboy.

Target audience:

Developers working in Erlang on distributed applications.
