The actor model builds fault-tolerant distributed systems by using isolated computational units that communicate through asynchronous message passing, allowing supervision strategies to manage failures and ensure system resilience without shared state.

To create an actor and send messages, you spawn an independent computational unit and deliver messages to its mailbox, enabling asynchronous communication where the actor processes received messages sequentially without blocking the sender.

Use the actor model for microservices or real-time applications when you need scalable, resilient architectures managing concurrent user sessions, such as individual chat user actors ensuring responsiveness under high load.

You need understanding of asynchronous programming and message-driven architectures, but no direct Erlang or Akka experience is required to implement the actor model for managing actor creation and fault tolerance.

The best way to manage concurrency in a real-time chat application is mapping each user session to an independent actor, utilizing asynchronous message passing to handle communication and ensure scalability without shared state locks.

Limitations of using message passing for fault tolerance include the need to handle asynchronous delivery delays and design supervision strategies manually, as the actor model requires understanding message-driven architectures to prevent system bottlenecks.
