About Actor Model

Professor Carl Hewitt published the famous paper Actor model of computation in 1974. In the thesis, he elaborates that:

An Actor is a computational entity that, in response to a message it receives, can concurrently:

• send a finite number of messages to other Actors;
• create a finite number of new Actors;
• designate the behavior to be used for the next message it receives.

With the rise of multi-core computing and large-scale distributed systems, the Actor Model is becoming increasingly important because of its natural concurrent, parallel, and distributed.
