# Erlang Concurrency

## Introduction

Erlang's concurrency model based on lightweight processes and message passing
enables building massively scalable systems. Processes are isolated with no shared
memory, communicating asynchronously through messages. This model eliminates
concurrency bugs common in shared-memory systems.

The BEAM VM efficiently schedules millions of processes, each with its own heap
and mailbox. Process creation is fast and cheap, enabling "process per entity"
designs. Links and monitors provide failure detection, while selective receive
enables flexible message handling patterns.
