The Actor Model, born in 1973, is a foundational concept in modern programming that addresses high concurrency, scalability, and fault tolerance in distributed systems. It revolutionizes the way concurrent computations are handled, treating every entity as an actor that communicates through messages. Each actor has its own state, can create other actors, and designates behavior based on the messages received. This model has been particularly influential in languages like Erlang and Elixir, optimized for these principles, promoting a high level of efficiency and resilience in complex computing environments involving numerous independent microprocessors.
The Actor Model enhances concurrency and fault tolerance, allowing independent actors to communicate via messages, making it a robust choice for scalable systems.
Originally created in 1973, the Actor Model stemmed from ideas in physics and programming languages, aimed at handling highly parallel computing tasks.
In the Actor Model, each entity is treated as an actor; actors communicate through messages and exhibit behaviors that determine their response to incoming data.
Message passing is central to the Actor Model, with every actor managing its mailbox—typically using FIFO—ensuring efficient communication and task prioritization.
