![]() Akka.NETĪkka is toolkit which allows us to create actor system in an efficient and simple way in. This can be considered limitation too because the synchronous behavior is harder to achieve. Also, this way race conditions would be minimal.Īnother benefit of these systems is that they are inherently asynchronous. This brings us to the fact that in actor systems, messages should be kept immutable, so they don’t change in the middle of processing and by that affect behavior of the system. What an actor will do is depending on what message it received. They are no longer just carriers of data, but also in a more abstract manner, carriers of behavior. Also, we should notice the importance of messages. It seems that it is natural to use actors in combination with Single responsibility principle, and make each actor do one thing (again pushing us to the concept of microservices). What is great about this model is that we can apply best object-oriented practices on it. We can consider that each microservice is, in fact, an actor in its own process. Also, we can find a use for this concept in rising world of microservices. This is due to the fact that actors can affect each other only using messages, and by that, all locks are eliminated. Especially in concurrent, parallel processing environments and distributed systems. But apart from that, we can definitely see that there is a great benefit in this model. Let’s not forget, that objects in Smalltalk-80 could hold state, and send and receive messages, and that does sound awful like the definition of an actor. Some of the authors are claiming that actors are actually the most stringent form of objects. designate the behavior to be used for the next message it receives.send a finite number of messages to other actors.According to the full definition of actors, they can do three things: ![]() Messages in actors are processed in a serial manner. Indifference to objects, however, actors communicate with each other exclusively through messages. An actor is the smallest structural unit of Actor model, and just like objects, they encapsulate data and behavior. Similar to the object-oriented approach, this essentially mathematical model, revolved around the concept of actors. and was developed on a platform of multiple independent processors in a network. In general terms, the Actor model was defined 1973. In the same time when first object-oriented languages were emerging, another concept inspired by general relativity and quantum mechanics was taking shape – actor model.
