- 9. Agenda Introduction and concepts Actor Systems Akka.Net Open Source Library Akka.Net SDK Networking and Remoting Clustering Using Akka.net
- 10. Introduction and Concepts Distributed Systems
- 11. Distributed systems A distributed system is a model in which components located on networked computers communicate and coordinate their actions by passing messages
- 12. Parallel and distributed computing In parallel computing, all processors may have access to a shared memory to exchange information between processors. In distributed computing, each processor has its own private memory (distributed memory). Information is exchanged by passing messages between the processors
- 13. Tipos de arquiteturas de processamento de sistemas
- 15. Actor Systems
- 16. Origem The actor model originated in 1973. It has been used both as a framework for a theoretical understanding of computation and as the theoretical basis for several practical implementations of concurrent systems The characteristics of today's computing environments are vastly different from the ones in use when the programming models of yesterday were conceived. Actors were invented decades ago by Carl Hewitt.
- 17. Fundamental concepts The actor model adopts the philosophy that everything is an actor. This is similar to the everything is an object philosophy used by some object-oriented programming languages.
- 18. Fundamental concepts 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
- 19. Messaging in OOP
- 20. Messaging
- 21. Ecosystems
- 25. Microservices Are a way to organize software by splitting each area of concern into its own deployable artifact
- 26. Microservices
- 28. Microservices
- 29. Actor Model Is a lower level than the deployable artifact, more about what types of objects you've implemented the service with
- 30. Actor System An ActorSystem is a heavyweight structure that will allocate 1...N Threads, so create one per logical application.
- 32. Supervision Dependency relationship between actors: the supervisor delegates tasks to subordinates and therefore must respond to their failures.
- 33. Akka.Net Open Source Library for Actor Model
- 34. Community-driven port Akka.NET is a community- driven port of the popular Java/Scala framework Akka to .NET.
- 36. Akka.Net is Open Source https://github.com/akkadotnet/Akka.NET
- 37. Reactive Manifesto Akka.NET adheres to the principles defined by the Reactive Manifesto. The Reactive Manifesto proposes a coherent approach to systems architecture in order to build systems that are more robust, more resilient, more flexible, and better positioned to meet modern demands.
- 38. Microsoft Actor Model A straightforward approach to building distributed, high-scale applications in .NET https://dotnet.github.io/orleans/

- 57. Dynamically Resizable Pools akka.actor.deployment { /my-router { router = round-robin-pool resizer { enabled = on lower-bound = 1 upper-bound = 10 } } } The following settings are used to fine-tune the resizer and are considered good enough for most cases, but can be changed if needed. Rules: https://getakka.net/articles/actors/routers.html
- 59. Akka I/O The I/O extension provides an non-blocking, event driven API that matches the underlying transports mechanism.
- 60. Akka I/O Client connection Server connection
- 61. Actor Path Actor have a unique address
- 63. Actor Path
- 64. Akka Remoting
- 66. Sending message on network
- 68. Using SSL
- 69. Remote Deploy That's right - we can deploy code over the network with Akka.Remote. Deploying an actor means two things simultaneously: •Creating an actor instance with specific, explicitly configured properties •Getting an IActorRef to that actor
- 70. Remote Deploy
- 71. Clustering
- 72. What is a “Akka Cluster“? A cluster represents a fault-tolerant, elastic, decentralized peer-to-peer network of Akka.NET applications with no single point of failure or bottleneck. • Fault-tolerant: clusters recover from failures (especially network partitions) elegantly. • Elastic: clusters are inherently elastic, and can scale up/down as needed. • Decentralized: it's possible to have multiple equal replicas of a given microservice or piece of application state running simultaneously throughout a cluster • Peer-to-peer: New nodes can contact existing peers, be notified about other peers, and fully integrate themselves into the network without any configuration changes. • No single point of failure/bottleneck: multiple nodes are able to service requests, increasing throughput and fault-tolerance.
