Message serialization

Another key aspect of distributed computing is the serialization of the message data that passes the JVM boundaries. Message serialization allows us to save the state of an object into a sequence of bytes, in order to allow us to rebuild the object with the state using the byte sequence.

In the case of Akka as well, whenever the message passes the JVM boundary, the principles of object serialization get applied. In Java, the serialization of a class is enabled when the class implements the java.io.Serializable interface.
