Project Orleans - Oredev 2014

This talk will do a deep dive into Project Orleans, a runtime and programming model for building distributed systems, based on the actor model. This session will go over the basics of the actor model, and the Orleans implementation of it. It will include an overview of the programming model, and patterns and best practices on how to architect distributed state-full systems using Orleans.

3. Orleans “Orleans is a runtime and programming model for building distributed systems, based on the actor model”
4. Overview • The Actor Model • Orleans Core Concepts • Build A System
5. The Actor Model A framework & basis for reasoning about concurrency A Universal Modular Actor Formalism for Artificial Intelligence ! Carl Hewitt, Peter Bishop, Richard Steiger (1973)
6. “An actor is an entity that encapsulates data & computation”
9. Orleans Actors
10. Single Threaded Code Execution
11. Virtual Actors “An Orleans actor always exists, virtually. It cannot be explicitly created or destroyed”
12. Virtual Actors • Perpetual Existence • Automatic Instantiation • Location Transparency • Automatic Scale out
14. Orleans Runtime • Messaging • Hosting • Execution
15. Reliability “Orleans manages all aspects of reliability automatically”
