Designing Actor Systems

Welcome to Lesson 2! In the previous lesson, we learned the basics of the Akka Actor Model. Now, let's dive into designing Akka Actor Systems.

A well-designed actor system is robust, scalable, and easy to maintain. We'll explore how to structure your actors, define their behaviors, and enable them to communicate effectively.

Akka actors are organized in a tree-like hierarchy, much like a file system. Every actor, except the 'root' actor, has a parent.

• Parent-Child Relationship: An actor that creates another actor becomes its parent.
• Supervision: This hierarchy is crucial for Akka's fault tolerance. Parents are responsible for supervising their children (more on this in the next lesson!).
• Path-based Addressing: Each actor has a unique path, reflecting its position in the hierarchy, like /user/parentActor/childActor.
