Akka is a framework for building distributed and fault-tolerant applications based on the actor model. The actor model represents entities as actors that communicate asynchronously by message passing and can maintain internal state. Akka allows building applications that are distributed, fault-tolerant, highly available, and can perform hot swapping of code and configuration at runtime.

2. Akka is for Actor Model
• Actor model
• Actor is an entity, similar to object in
OOP
• Actors communicate by messages
(share nothing)
• Actor can be stateful or stateless
• Actor can save to persistent storage

3. Why Akka
• AKKA is good for an app
• distributed
• fault-tolerant
• soft real-time
• highly available
• non-stop (hot swap)
