Distributed Elixir and Clustering

Welcome to distributed Elixir! This powerful feature allows your applications to run across multiple machines, forming a cluster of interconnected nodes.

Why is this important? It provides:

• Fault Tolerance: If one node fails, others can continue or take over.
• Scalability: Distribute work across many CPUs or servers.
• Concurrency: Manage many concurrent operations with isolated processes.

This capability is built upon the Erlang Virtual Machine (BEAM), which Elixir runs on.

In Elixir, a 'node' is a running instance of the Erlang VM, typically hosting your Elixir application. When you start iex, you're starting a single Elixir node.

For distributed systems, nodes need to be able to find and communicate with each other. This is done by giving them unique names.
