Understanding OTP & Behaviors

Erlang is great for concurrency, but building robust systems from scratch can be complex. OTP, short for Open Telecom Platform, is a powerful set of Erlang libraries, design principles, and a framework.

It helps you build fault-tolerant, scalable, and maintainable applications with ease.

Erlang's lightweight processes and message passing are powerful building blocks. However, managing all processes, their state, and restarts manually can become very complex.

• Processes: Isolated units of execution.
• Message Passing: How processes communicate.
• Fault Tolerance: The ability to recover from failures.

OTP provides abstractions to simplify these challenges, letting you focus on your application logic.
