Distributed Systems

OTP's support for distributed systems is something that set Erlang and Elixir apart from other programming languages.

The BEAM vm is designed from the ground up to support distributed computing. With minimal efforts, you can have multiple Erlang/Elixir nodes running on different machines that can seamlessly communicate with each other.

Those nodes can form a cluster out of the box. Nodes can automatically connect to each other, share state, and communicate as if they were a single system, even if they're running on different machines or across data centers.

In most other languages, it usually require external libraries, frameworks, or infrastructure to provide essential services to set up distributed systems. Which includes:

• Service Discovery
• RPC
• Load balancing
• Auto-scaling
• Self-healing
• Tracing

iex --sname foo@localhost -S mix

iex --sname bar@localhost -S mix

iex(bar@localhost)1> Node.spawn_link(:foo@localhost, fn -> Counter.incr end)

iex(foo@localhost)1> Counter.get_count
